Executive summary
Background and research objectives
Melbourne Water’s values – Care, Integrity and Courage – and its vision of “Enhancing Life and Liveability” provide a profound imperative for the organisation to put Melburnians’ wellbeing at the centre of its work – and to engage them in an open and transparent process about current and future developments.
The 2021 price submission will help set Melbourne Water up to lead the supply of essential services that deliver enormous value to customers. Melbourne Water’s internal experts have identified a range of innovations in service delivery that offer enormous potential for the organisation to better meet its vision. However, these innovations require investment from the community, and their willingness to engage with and invest in Melbourne Water’s vision will be a critical factor in its long-term success.
To this end, Melbourne Water engaged Whereto to conduct community research with a representative cross-section of Melburnians. Following on from a qualitative phase comprising 12, 3-hour focus groups and an online discussion board in late 2019, a large scale (n=2,549) representative online survey of Melburnians was conducted over January 2020.
Focus group and survey participants were provided stimulus material, including text, images and audio describing the need for each of the initiatives, as well as a range of potential options for additional investment around:
Bill certainty
Biosolids re-use
Water recycling
Stormwater harvesting
Access to open space and recreation
Sewerage
Carbon offsets
Managing runoff from hard surfaces
Ecotourism development at WTP
Educating Melburnians
The research was designed to elicit bill payers’ willingness-to-pay for a range of different initiatives, including a simultaneous trade-off analysis that pitted each of the initiatives against the estimated increase in their yearly bill.
Summary of findings: Key themes
Water security and a high functioning sewerage system are essential investments
Melburnians support decisive action to ensure our city’s water security and a high functioning sewerage systems in the face of population growth and climate change. They believe greater investment in water security and sewerage system resilience is essential to Melbourne’s future as a liveable, prosperous city. Some can name cautionary examples overseas where environmental context and poor planning has led to almost apocalyptic water security outcomes (e.g. Johannesburg), and compromised conditions more locally (e.g. in western NSW) – for participants across our groups, it is unthinkable that this could or would be allowed to happen to Melbourne.
“If we haven’t got water security, we’re in trouble – look at Flint Michigan – it’s a huge issue even in first world countries, sewerage and water delivery is vital, or it affects everyone in our community and our wellbeing.” Male, 60+ Located within South East Water’s region
page 5
Melburnians are looking for evidence that Melbourne Water is a responsible actor
How investments to ensure water security and a high functioning system are made will determine perceptions of Melbourne Water as a good manager, and whether people are willing to give their support to those investments. Melburnians have decisive opinions on:
the benefits of acting now vs later,
the extent to which the full potential of investments are realised through a systems approach,
whether Melbourne Water should act outside/beyond what they understand to be its core business of water security/sewerage, and
whether Melbourne Water’s actions should benefit a subset of people or the whole community.
In more detail, the community want to see:
Evidence of strong forward planning and considered action... While people are appreciative that
Melbourne Water has taken the time to ask them about water security, sewerage system resilience and
other important issues, they are also concerned that these issues are being addressed in a reactive fashion.
They can easily list off numerous other examples where Melbourne’s infrastructure isn’t keeping up with
population growth – roads, schools, transport, housing, etc. – and are looking for evidence that Melbourne
Water is doing responsible forward planning.
Acting in advance is not only seen as being a cheaper option for infrastructure investment, it is also
considered essential to Melbourne Water being seen as a wise, shrewd and sensible actor. Melburnians
want to feel that they are receiving the best value for money, that actions are assessed in terms of short and
longer term implications, opportunity cost, financial viability, potential benefit, the broader environmental
impact and whether they can eventually become self-funding or can feed revenue back into the system.
“What I really appreciated about the information was seeing how proactive Melbourne Water are being about so many things... I commented on the homework that our Federal Government could take a few leaves out of their book! I think it's very smart to be thinking ahead about infrastructure and impact on the environment. I think being ready for things before you have no choice and have to make a contingency plan is really important, across the board!” Female, 35-59, chronic Illness, Located within Yarra Valley Water’ region
Holistic system integration for long-term sustainability… That a growing population increases pressure on
existing systems was readily understood, accepted and set a compelling framework to consider the mix of
initiatives – despite some misgivings around the costs and benefits of population growth. Melburnians are
reassured that a comprehensive range of initiatives for their city’s long-term future are being considered
and pursued. They appreciate that Melbourne Water is taking a holistic, future focused approach and
attributed benefits both to the specific initiatives but also to their combination.
In particular, people wanted to see evidence that Melbourne Water’s initiatives reflect wise and
interconnected use of the system as a whole. There is greater support, for instance, for recycling, or
optimising existing resources (e.g. through bioenergy or solar panels on treatment plants) than for new,
standalone initiatives. Related to this, people are much more accepting of initiatives that involved
‘prevention rather than cure’ – for example, emissions reduction rather than carbon offsets.
“Melbourne Water seems to be thinking well ahead about challenges we might face in the not-too-distant future, and I think this is the smart way to go. I think it's wise to be concerned about water security generally, so knowing that Melbourne Water is looking to mitigate any issues early is reassuring.” Female, 35-59, chronic illness, Located within Yarra Valley Water’s region
A focus on Melbourne Water’s core business… The scope and importance of Melbourne Water’s work is
unarguable. However, Melburnians are divided on initiatives outside Melbourne Water’s core business of
page 6
delivering water and sewerage services – for example, providing tourism infrastructure. They are quick to
point to local and state governments having greater responsibility in those areas.
“It’s vital, the work [Melbourne Water] do, without it, none of us would be here – they keep us and the environment healthy” Male 60+, Located within South East Water’s region
Benefits that flow equally to all Melburnians… In discussion groups, there was lower levels of support for
investments that only benefit a subset of Melburnians – for example, pipe track parks that were perceived
to only benefit people living in particular Melbourne areas, or odour management strategies that only
benefit those who have bought houses near treatment plants or exhaust stacks. Even where a project may
only add a few cents to an average water bill, in discussions people typically rejected these projects based
on the principle of universality – that the benefits of Melbourne Water investments really do need to be for
all Melburnians. Where citizens could envisage the broader social benefit of these initiatives, they could be
more supportive
Burden on business vs community … There was some resentment in group discussions that the burden of
water infrastructure was being talked about solely in terms of household, rather than business
responsibility.
“One thing I noticed was that this is all about what households have to do. That’s not fair… what about business, they use more!” Female, 60+ years, Located within City West Water’s region
“This all needs to be done as efficiently as possible, and I don’t see why we should have to be charged more – it should be part of an efficiency dividend.” Located within Male 60+ Yarra Valley Water’s region
Involving the community and explaining the issues further
This analysis also suggests that it is not enough for Melbourne Water to act in people’s best interests and in a responsible manner – people also need to know that it is acting. There was, in addition, a near universal desire among Melburnians to personally contribute to water security, and to further understand the issues. In more detail:
Melburnians want to play a part… Melburnians want to know how they can contribute to our water
security. Those who recall it are nostalgic about the Millennium Drought water restrictions, and younger
people are highly concerned about climate change. They would be happy to take more personal
responsibility in relation to reducing household’s water use.
Melburnians are also surprisingly eager to make a contribution (through their water bills) to water infrastructure. The exception is people who argued strenuously that system improvements should be funded through Melbourne Water’s dividend to Government, or via efficiencies across the system.
“I just want to know what else we can all do to help – we can all use water better and save the need for some of these things.” Male 25-35, Located within South East Water’s region
More communication about water issues / solutions welcomed… Participants in every group initially
expressed sense of surprise at the scope and breadth of Melbourne Water’s work and its importance to our
city. Few without direct involvement in Melbourne Water or its predecessors had any understanding about
what Melbourne Water did, or the complexity of the systems that it manages. This included most of the
issues and innovations covered in the document shared with participants prior to their sessions.
Melburnians are typically interested in learning more about the water issues facing our city; and how
Melbourne Water is planning to tackle these.
page 7
“I didn’t know Melbourne Water was into desalination and recycling, and carbon and offsets so this was something new to me and I wanted to know more about Melbourne Water and what they do.” Female, CALD, 25-35, Located within City West Water’s region
“I was very happy to hear they were into things like clean energy and renewables – I didn’t know they were into it so much.” Female 25-35, Located within South East Water’ region
While most participants could accept an increase in bills, this was not without a desire for greater accountability – Melburnians expected that Melbourne Water would and should share its progress on any new initiatives. Most assumed this could be communicated on their bills – with simple visuals or statements on what the initiatives are and progress made. Some expected that Melbourne Water should invest in local signage and advertising that also showcases how water is being used – and how the system is being managed - responsibly.
Assumptions about the nature of water retailers and Melbourne Water need to be addressed… Many
across our groups – especially those in younger generations – indicated a belief that Melbourne’s Water
retailers are private, profit-making companies, rather than state-owned enterprises returning a dividend to
the government. This stems partly from their being referenced to as ‘retailers’, and the nature of other
utilities services in Victoria. In other words, participants expectations were set by the context of other
essential services, for example electricity and gas in Victoria, where the retail, customer-facing billing
agencies are not usually government owned, but are private companies.
“I didn’t know that Melbourne Water was a Victorian Government body – that surprised me from the reading pack.” Male, 25-35. Located within South East Water’s region
In the absence of being told otherwise, it is natural for many Melburnians in our discussion groups to have
thought that water runs on a similar model. This does have a significant impact on perceptions – especially
when asking people to pay increases to fund community initiatives, and should be addressed.
Summary of findings: Response to specific initiatives proposed
Across the discussion groups and the online survey, Melburnians revealed strong levels of support for a majority of the initiatives proposed, and a willingness to invest alongside Melbourne Water to see them borne out. To illustrate, across the groups, people were willing to pay an additional $60-$80 per annum to help fund their choice of initiatives, and in the quantitative survey, Melburnians indicated an average willingness to pay for their choice of initiatives of $18.88. The difference between these figures can be mostly ascribed to the different cost bases presented in the different streams of research.
“So what’s that $70 – so $1.50 a week and we get all that – I wouldn’t have a problem with that.” Male, 25-35, South East Water
The quantitative survey showed that more than half of Melburnian water bill payers were willing to pay for more than the minimum investment for every initiative, with exception of ecotourism facilities at WTP (44%). Only one in ten (11%) bill payers were not willing to pay more than the minimum across any of the areas included - a clear majority (89%) are willing to pay for greater investment in one or more of the initiatives detailed in the survey.
The most favoured initiatives presented to participants were (in order):
Stormwater harvesting… Melburnians across all group discussions were strong supporters of increased investment and focus on stormwater recovery and recycling. Many felt this was a priority area for investment – that letting stormwater go into the bays is wasteful, and that we should be collecting and re-using more of it throughout the year.
In the quantitative survey, increasing the amount of stormwater harvesting was the most strongly supported option overall, with three-quarters (75%) of Melburnians willing to pay for additional investment.
page 8
Sewerage system resilience… Participants across our group discussions were strongly and nearly ubiquitously supportive of greater investment in ensuring our sewerage system is resilient and ready for the future challenges of population growth and climate change. The risk of a leaky or unsound sewerage system is not a risk that Melburnians are willing to take.
In the quantitative survey, investing in sewerage system resilience had very strong support (72%), almost all Melburnians (87%) agree it’s important to ensure the sewerage system is fit for future generations and our growing population, to ensure a healthy environment for all Melburnians and avoid the risk of issues emerging later.
Carbon offsets…Carbon offsets are not necessarily a well understood topic – some people required a great deal of explanation in addition to the reading pack to digest the information and consider the options - carbon offsets are confusing for many, and have some level of distrust in the community. In addition, the idea of carbon offsets can be contentious. Age divides on this issue, with many of those in older groups more distrustful of offsets, and less likely to favour rapid offsets, if at all. Younger groups were much more supportive.
The quantitative survey reinforced these findings the options presented were highly polarising – with roughly a third (37%) opting for the cheapest possible, and a third opting for high value local versions at the highest cost (34%). However, overall, 69% supported faster abatement or higher quality, Australian based carbon offsets than the minimum required by the government.
Pipetrack access and amenity… While few in discussion groups had any objections to the idea of opening up pipe tracks – and most felt that it is an idea with merit – almost everyone across the group discussions felt that those more likely to use these areas (that is, those who live nearby) should cover any costs required to do so.
In the quantitative survey, the low costs ($0.04) involved meant that improving pipetrack access and amenity was strongly supported (69%) – clearly seen as low-cost, good value improvements to create green corridors and for urban cooling and air quality – it added a total of $0.17 to the average increase.
Access to open space and recreation…In focus groups, many showed support for a range of recreational uses around the “downstream” reservoirs, as is already the case. Some can imagine an argument for opening up the reservoirs further, including allowing people to recreate in the water. However, in tension with this, people are concerned about water contamination, increased fire risk or even acts of deliberate terrorism becoming more likely if our pristine catchments and reservoirs are opened further to the public. People were also much more comfortable with the idea of expanded recreation being funded by general tax revenues than via their water bill.
In the quantitative survey, a majority (62%) of Melburnians are willing to contribute to opening up reservoirs to make better use of our beautiful natural spaces for the benefit of the community. Very few do not support Melbourne water providing access to land and reservoirs (11%).
Recycled water…Broadly, the idea that Melbourne could and should be recycling much more water found very strong levels of support across the group discussions, with most reframing it as a responsible waste use and a water security issue. In the quantitative survey, greater levels of water recycling was supported by a little over half (56%), but accounted for the second largest proportion of the average total increase in water bills ($3.07). Bill payers identified reducing effluent into the bays and putting our waste to good use as the key benefits.
Education and awareness… Melburnians are highly supportive of greater investment in water education. After considering the pre-reading pack and discussing Melbourne’s water supply and management options, virtually all participants felt there was a need for ongoing communications informing Melburnians about the water system, Melbourne Water’s work, and how individuals can help by being better users of our water resources. Slightly more than half (56%) in the quantitative survey supported more than the current level of investment in education via digital education programs and interactive facilities. The key benefits noted were improving water use behaviours, and increased awareness about Melbourne’s water, and where it comes from.
Biosolids re-use... Few Melburnians are aware that biosolids are created from our sewage stream, or that there is currently a stockpile of around 20 years’ worth of biosolids. Across discussions, people were shocked (if not
page 9
horrified) that such a large amount of biosolid could be amassed without them hearing about it, and were surprised that they weren’t re-used as a standard practice for managing the sewage waste stream. But there were tensions around the requirement for additional investment. In the quantitative survey, biosolid re-use options were among the least supported (54%), but contributed $0.98 to the average total bill increase. Putting our waste to good use, fully treating and re-using waste, and helping farmers were identified as the key benefits.
Bill certainty… Perceptions of the desalination plant have been shaped by (tabloid) rumour and (mis)information – and many came to the groups with negative views, including a widespread lack of real knowledge. Despite this, many feel that desalination should be used more extensively, to provide Melbourne with greater water security, and as a buffer against drought, growth and climate change. Although the second-least favoured proposal in the quantitative survey, with only half (52%) favouring a shift from the current arrangement, the price attached to the options meant that this accounted for the highest proportion of the total average bill increase. Bill payers felt the most important benefits were stable predictable bills and water security.
Ecotourism at WTP…Ecotourism was the least supported option, only 44% in the quantitative survey opted for more than maintaining current approach. Better facilities for schools and improved water and sewerage literacy were seen as the main benefits of increased investment.
Impervious surfaces… Melburnians have not heard about – or considered –the issues with increasing impervious surface area and development across the city. However, the issue makes intuitive sense once people have read or heard about it – few need further convincing of the challenges. Nearly everyone across the more extended and in-depth analysis of focus groups felt the flat charge for impervious surfaces to be unfair. However, in the quantitative survey, with the pros and cons of each approach clearly spelled out, over half (56%) supported no change to the current approach to the impervious surface area charge.
The cost attached to each of the initiatives is also an important variable that needs to be incorporated, because each of the options had very different costs attached the bill payer’s estimated increase. The initiatives with that added, on average the highest amounts to the average water bill were:
Bill certainty ($10.08, from options of $0, $16 and $32 per annum) Water recycling ($3.07 from options of $0 and $5.49) Stormwater harvesting ($2.06, from options of $0, $2 and $4) Access to open space and recreation ($1.19, from four options ranging from $0 to $5) Biosolids re-use ($0.98, from options of $0.62 and $1.42)
The contrast between these two analyses highlights an important overarching theme from the research: the community broadly supports low incremental cost, high value initiatives (like stormwater harvesting, sewerage system upgrades, better carbon dioxide offsets and pipetrack access and amenity).
But there is also a substantial proportion who see Melbourne Water as trusted experts, who support all of Melbourne Water’s recommendations to enhance life and liveability – and who are willing to bear the cost.

Background and methodology
Background
Melbourne Water plays a variety of essential roles in our community
Melbourne Water is an increasingly customer-focused organisation, focussed on providing ever better value and service to the people of Victoria. Customer-centricity in utilities providers usually requires an absolute dedication to uninterrupted service delivery at minimum cost. However, Melbourne Water delivers services far beyond that of an average utilities service provider or water retailer. With services covering reservoirs and catchments, sewerage, the management of high-quality waterways, drainage and flood systems, Melbourne Water takes the lion’s share of responsibility for the healthy environment and essential living standards that all Melburnians rely on and enjoy.
Melbourne Water also manages large tracts of land – over 33,000 hectares – that provide local amenity and recreation opportunities, and supports local communities to help them make the most of these amenities.
Melbourne Water’s vision is “Enhancing Life and Liveability”, which is supported by three pillars: Healthy People, Healthy Places and Healthy Environment. This vision underpins the delivery of all Melbourne Water services.
Balancing development with human safety and environmental health is a core organisational challenge. Ensuring that our city remains the world’s most liveable, in a future where our population will reach over 8 million residents, relies on strong community collaboration and engagement. Melbourne Water’s values – Care, Integrity and Courage – articulate the imperative for the organisation to put Melburnians’ wellbeing at the centre of its innovation program – and to engage them in an open and transparent process about future developments.
Innovating service delivery
The 2021 price submission will help set up Melbourne Water to lead the delivery of essential services that provide enormous value to customers. Melbourne Water’s internal experts have identified a range of innovations in service delivery that offer enormous potential for the organisation to better meet its vision.
However, each of these require investment from the community, and community willingness to engage and invest with the organisation in meeting its vision will be a critical factor in long-term success.
The potential evolution of Melbourne Water’s services include:
1) Alternative base water service and investment scenarios — covering changes in catchment
management, including the opening of currently closed areas for recreation.
2) Upgrading long-term water security — normalising use and augmentation of the desalination plant,
potential for a second plant, potential alternative sources — including recycling — as well as
technology and research investment.
3) Recycling water from sewerage —introduction of new water recycling plant and processes to
enhance long-term water security and resilience.
4) Integrated water management — a range of integrated water management projects and scenarios,
including many with additional community benefits.
5) Base sewerage service — scenarios covering research and technology, education and system
resilience.
6) Bio-solids – scenarios regarding bio-solid re-use, including rate of meeting re-use targets and
investment in technology to explore alternative re-use options.
7) Carbon offsets – carbon neutrality through investment in carbon credits including potential for
sourcing credits both locally and overseas.
page 11
8) Liveability initiatives – relating to water and sewerage services – investing in liveability outcomes
associated with water and sewerage services.
9) Impervious surface area charging – potential for charging based on the impervious area of residential
and non-residential properties, potential offset options for reducing the charge.
Melbourne Water is focussed on delivering a sustainable and best-practice service that is in line with community expectations. As part of its engagement program for the 2021 Pricing Submission, Melbourne Water has drawn on the insights of a representative panel to co-design a community vision for the Price Submission.
“In 2026, Melbourne Water is ensuring the environment is central to all it does. Its sustainable and innovative approach to service delivery provides reliable, efficient and secure outcomes for everyone
and everything. Melbourne’s water is for us and for you.”
This vision is supported by six priority values, including
Environment and sustainability,
Reliability,
Forward thinking,
For everyone,
Innovation, and
Efficiency.
These six priorities are supported by another six values including: honesty and integrity, education, quality,
transparency, system-wide collaboration and value for money. This vision and these values underpin the
approach to community engagement around any potential evolution of Melbourne Water’s services — and in
exploring the community’s willingness to invest alongside Melbourne Water.
Need for community research
As Melbourne Water develops its 2021 pricing submission, it is important to provide ongoing evidence around the community’s perceptions of the value of Melbourne Water’s services. This project will realise parts of Stage 2 of Melbourne Water’s Community Engagement program, which aims to collaborate with the community to understand their preferences around and willingness to pay for services. The community’s response to the Engagement Program will help to inform and define the priorities of the Price Submission.
The objectives of this research are therefore to:
Explore the community’s attitudes and willingness to engage across each potential evolution of Melbourne
Water’s services
Assess, via a robust, population-representative sample within Melbourne Water’s area of service delivery,
the preferences and willingness to pay for potential innovations
Validate and deliberate — provide robust and well-considered direction for Melbourne Water, building on
and refining the options with the strongest community support and willingness to engage.
Methodology
This report summarises findings from the first (explore) and second (assess) phases of the research.
Explore: Qualitative research
The initial qualitative phase was designed to provide a detailed understanding of community perspectives on Melbourne Water’s proposed initiatives.
Melbourne Water | Pricing Submission 2021 Community Research | February 2020 page 16
Twelve, 3-hour discussion groups with pre-reading
Group discussions are an ideal way to understand the views and perspectives of a broadly representative and inclusive group of Melburnians; a well-run group discussion allows discussion and debate — and a full exploration of people’s reactions to stimulus.
In this case, we were interested in how the issues may play out in the community once people understand and have considered them. These are long-term investments that must be properly considered for their costs, benefits and risks. To this end, we ensured that participants came to discussions well prepared, having familiarised themselves with the concepts via both printed and audio stimulus designed to inform about the key issues in a neutral way. A copy of the printed stimulus can be found at Appendix 1.
Sample
Effective qualitative sampling builds on the well-established principle that groups run best and provide the most accurate perspective when they are based around relatively homogenous demographic groupings. For this reason groups were separated based on:
Gender – Women and men talk differently about the issues, and gender-specific groups encourage
participants to more freely express their feelings and opinions.
Age – Different generational cohorts have different levels of experience with Melbourne Water’s services
and talk about their needs and express themselves in different ways.
Level of education / SES – Level of education is an important predictor for the interpretation of complex new
ideas. For the purposes of qualitative samples, level of education is an excellent proxy for both level of
literacy and socio-economic status, and this makes it an important variable to control.
Location — Location within Melbourne dictates which water retailer participants rely on, the Melbourne
Water services they receive or have regular exposure to, and a host of cultural differences. Groups in South
Melbourne included South East Water and City West Water; those in Hampton included South East Water
customers only; those in Ringwood and Healesville included Yarra Valley Water customers only; and those
in Coburg included City West Water customers only.
Other demographic characteristics — such as household size and land ownership, lifestyle, life stage, cultural and linguistic diversity (CALD) and work status — were carefully controlled within each group to ensure broad representation. All participants were water bill payers.

Groups were audio and/or video recorded at all locations.
Online discussion board: people with disability and chronic illness
An online discussion board was used to facilitate the inclusion of those with chronic illness and physical disability who might otherwise find it difficult to participate. People with chronic illness and disability that limit their ability to participate in group discussions make up between 10% - 20% of the population. That their voices are often under-heard in our community because of their different ability to get to central locations for group discussions makes them an important group to include in a project designed to be representative of all people’s needs.
participants were required to engage over on separate days – examining different scenarios each day. This was conduced over the course of a week. The online discussion board was actively moderated by our team, offering expert questioning/probing approaches that ensure high levels of participant engagement.
The online panel discussion included 16-20 individuals, selected to offer a representative range of disability and mobility-limiting chronic illness.
Assess: Population representative survey
This phase of the community research comprised a large-scale online survey of n=2549 Melburnians. The survey took an average of 29 minutes to complete, and included detailed descriptions of the different initiatives being proposed by Melbourne Water for the next pricing submission period (2021-2025). The questionnaire, including the descriptions of the initiatives proposed is provided in the appendix.
The method was designed to provide participants with a realistic, digestible overview of the subjects, and asks them to prioritise either lower bills (e.g. by choosing the options with the lowest bill impact – usually $0) or greater investment in our water and sewerage infrastructure.
The survey focussed on water bill payers’ willingness to pay for the range of initiatives presented. The costs of each option were provided throughout the survey, and again through a SIMALTO experiment, where participants traded off all the initiatives simultaneously against a hypothetical increase in their total annual bill.
Melbourne Water | Pricing Submission 2021 Community Research | February 2020 page 18
Notably, to keep the survey under 30 minutes, participants were randomised such that while all completed the choice of options after going through the stimulus, only half completed the follow-up questions for each initiative. The order of sections presented to participants was also randomised to minimise order effects.
Sample:
The sample was designed to be representative of a range of demographic indicators and water retailer locations – achieved sample details are set out below; a sample of n=385 small and medium business owners / managers was also included (Table 1).

Audio versions of the descriptions were made available via the survey to encourage those for whom reading is more difficult and enable them to thoroughly review the material. The survey was presented in a fully accessible format, suitable for those using screen readers.
YourSay
This survey was also made available to members of the community via Melbourne Water’s YourSay page. A total of n=32 community members completed the survey from this link. These respondents were found to be atypical compared to recruited members of the general population, showing greater acquiescence to increased billing and awareness of issues faced my Melbourne Water - for example, 69% of those accessing the survey via the YourSay page were aware that impervious surface area growth is major and growing challenge for waterways and bays, compared to just 21% of those from the recruited general population sample.
Because these respondents were not representative of the broader population, they have been excluded from analysis discussed in the main body of this report. We do however note that these community members represent a highly engaged segment who are more likely to pay more than the minimum on all initiatives.

Participant feedback:
The online survey required participants to read large amounts of information and was therefore longer than normally recommended to maintain engagement. Several strategies were used to maintain participant engagement, including providing participants the option of listening to audio recordings of information and providing supporting images to ‘break up’ large amounts of text.
These strategies appear to have been successful, with many participants providing positive feedback in a final, optional, open-ended question. Key themes expressed by participants include the survey itself being engaging and interesting, interest in the topics raised in the survey and being thankful for an opportunity to express and share their views. However, a few participants still felt the survey took too long to complete.
“Very involving and well written/detailed survey. Also, great use of images to paint a more relevant picture.”
“Interesting topic. I feel better informed now.”
“Very interesting and informative and thanks for allowing my views to be part of the future planning.”
“I am really thankful for the experience while doing this survey, I learnt a lot about Melbourne Water, it’s current issues and future goals and ambitions. It is amazing.”
“Excellent survey about a very relevant topic, our water supply. Without water the human race would become extinct.”
“I really enjoyed this! It was very interesting and had thought provoking questions - I especially liked the final personal tally of proposed cost, as it really puts your money where your morals are. This is also the first survey I've done offering an audio version for the graphics and I just thought it was awesome to see that option included! Thanks.”
“This has been one of the most interesting surveys to date and it has opened my eyes to so much more about Melbourne water!”
“Pleased to hear that Melbourne Water is looking to the future and thinking about ways to make the best use of precious resources.”
“Very long survey but good with the audio.”

Findings in detail
Comparison of options
At an overall level, the highest proportion of Melburnians were willing to pay for additional investments in stormwater harvesting, sewerage system upgrades, better quality or faster offsetting of CO2 than required, and opening up access to pipetracks (Figure 1).
Over half of Melburnians were willing to pay for every initiative tested (with the exception of ecotourism at the WTP), and nine in ten (89%) were willing to pay for at least one of the initiatives.
Figure 1: Comparison of preferences – simultaneous trade-off with bill yearly increase
However, overlaying the costs of each option tells a different story. While only half (52%) were willing to pay for bill certainty, the weighted average increase in bills as revealed in the SIMALTO – which is influenced by the price of the options- shows that those who choose this option are responsible for over half the average total increase in water bills.
By this measure, water recycling ($3.07), stormwater harvesting ($2.06) and access to open space and recreation ($1.19) were the most strongly supported after bill certainty ($10.08) (Figure 2).
Bill payers were, prepared to pay, on average $18.88 additional for the options they selected in the survey.

The small-medium business owner sample revealed very similar priorities throughout the survey to the broader
population.
On average, this group appeared to be slightly more willing to pay overall, and slightly more willing to pay for the more expensive options, but these differences
were not generally substantial.

Figure 2: Average contribution to total bill increase
The contrast between these two analyses highlights an important overarching theme from the research: the community broadly supports low incremental cost, high value initiatives (like stormwater harvesting, sewerage system upgrades, better offsets and pipetrack access and amenity), but there is a substantial proportion who support all of Melbourne Water’s proposals – and are willing to bear the cost.
The following sections provide more detailed analysis of responses to each of the initiatives.
Bill certainty and water security
The desalination plant is strongly relied on as a water ‘safety net’ for Melbourne - the community firmly believes that if other water supply options fail then we can rely on the desalination plant.
However, beyond this, perceptions of the desalination plant are shaped by (tabloid) rumour and (mis)information. For many, the last information they had heard about the issue was many years ago. In groups, people raised ideas relating to:
cost blowouts and inefficiencies involved in construction
the notion that the desalination plant is inefficient because we have to operate it whether we need the
water from it or not
the notion that the desalination plant is not operating
the feeling that it was a wasteful investment because the drought broke as soon as building finished and the
project was therefore unnecessary
“I wasn’t aware we were using the desal plant” Male, 25-35, located within South East Water’s region
“I don’t understand why we aren’t using the desal plant?” Male, 35-59, located within Yarra Valley Water’ region
“I didn’t know the desal plant had been turned on – I thought it was just mothballed and a massive waste of money” Male 60+, located within Yarra Valley Water’s region
Despite a lack of good information now, Melburnians are highly supportive of desalination playing a greater role in securing Melbourne’s water security. Many feel that desalination should be used more extensively, to provide Melbourne with greater water security, and to provide a buffer against drought, growth and climate change.

However, there was concern about desalination being the ’primary’ or only water source, because:
it doesn’t seem as sustainable as using storm or recycled water. For example, younger participants had
concerns about the energy required (most weren’t aware that the Wonthaggi plant uses 100% renewable
energy for its operations)
“I’d want to see it using a lot more renewable energy.” Female, 25-35, located within City West Water’s region.
“For me, the fact that our desalination plant uses so much energy stood out. I think this definitely should be of concern. Although it is good we're able to use the desalination plant when needed, should we be looking at more eco-friendly sources?” Female, 25-34, located within City West Water’s region
“I’m a bit uncomfortable about the idea that we can just engineer our way out of any situation. I’d rather just do the right thing in the first place.” Male, 25-35, located within City West Water’s region
those few who understand desalination well know it be an expensive option and question its value.
There is no sense that a second desalination plant might be required – the ground will need to be very carefully laid if there is to be community support for this option.
It’s important to note that the options presented in qualitative groups (Figure 3) were actually not about actual production of water, but providing bill certainty – adding a charge for anticipated normal production, smoothing out bill fluctuations and ensuring any surprises were minimal. In relation to this, some had a preference for support in managing their finances; others were more independently minded. The more astute noted that bill smoothing is not fail-safe, and that if extra water is required, then unanticipated bill increases would still occur.
Figure 3: Desalinated water order options provided in group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
However, people’s instinctive tendency was to interpret this option as being about paying for greater production: producing water from the desalination plant regardless of whether it is needed, providing a larger buffer against times of drought and hence more water security. Their choice of options should be framed through this lens, as much as choice of bill certainty.
Between the three options provided to them, a larger proportion of participants (in some groups it was everyone, in others it was only half) were happy with paying for the higher ”assumed amount” levels, which they felt guaranteed more water into the system. Older groups (50+) were much better informed about Melbourne Water’s activities, and they tended to be shrewder with their investment decisions, and argue against Melbourne Water’s narrative and the options presented to them. However, even these groups, when

forced to decide about funding for desalination, mostly chose a perceived investment in line with the average presented below; only a few wanted to maintain the status quo of a $0 increase.
This meant, on average, groups were prepared to pay $15-25 additional per year to provide the comfortable feeling of water abundance – a city and a broader environment with more than enough water.
“We’ve got it there, we’re already paying the capital costs, we should be using it.” Male, 60+, located within South East Water’s region
“I'm in favour of additional desalination plants being brought online as the need arises. If rainfall and other means of supply are restricted, we need a plentiful supply from somewhere and the oceans seem the logical option. My only concerns would be the cost, which I assume could come down with newer technologies; and the time lag to bring them online to meet population needs.” Male, 60+, disability, located within Yarra Valley Water’s region
“I remember the last drought very clearly and how we had to cut back showers, use bath water to water gardens, if it's yellow let it mellow and so on. It was an uncertain time and a bit scary. Water security is very important so it doesn't happen again. Things like desalination and stormwater catching really stood out to me. Desalination being something that excited me as we have a vast ocean which can also be a wonderful source.” 35-59, Female, Chronic illness, located within Yarra Valley Water’s region
Water security is dominant frame that strongly impacts the way Melburnians think about water.
The quantitative survey took a different approach to examining preferences for planned water orders, de-emphasising water security, and focussing participants on bill certainty. This was done deliberately as the qualitative groups had shown people were strongly influenced by the pre-reading material that stated facts about the frequency of droughts, and highlighted the pressures of a growing population and climate change, rather than strictly a greater desire for bill certainty. A majority of the difference in response – where the qualitative phase suggested most would be interested in higher planned water orders, the quantitative phase revealed only half were willing to pay for anything above the current status quo – can be put down to this difference in framing between the phases.
A key lesson for Melbourne Water and regulators is that the of framing issues around water security, or an environment where water security issues are more salient (e.g.: a drought) is likely to strongly influence the level of support for water saving and production initiatives, including desalination, but also stormwater and recycled water.
In the quantitative survey, participants were provided with information about the uncertainty of the impact of desalinated water orders – which are made by the Minister each year on advice about their necessity - on household water bills (Figure 4).
Three options to smooth the costs of desalinated water orders were proposed to participants:
1. Maintain current billing arrangements (No change to water bill) 2. Increase annual water bill to include a planned amount of $16 3. Increase annual water bill to include a planned amount of $34
Quantitative results showed that half of Melburnians (48 - 51%) would prefer to maintain current billing arrangements for desalinated water orders, while the other half would prefer to include planned amounts.
One in three (37 - 41%) preferred the smaller water order ($16/year) while one in ten (11-12%) preferred the larger order ($32/year).

Figure 4: Desalinated water order – Melburnians’ willingness to pay
Bill payers more likely to wish that the status quo be maintained include:
Males (54% compared to 49% of females), and Those aged 55+ (58% compared to 54% aged 35-54 and 41% aged 18-34)
Billy payers with an annual household pre-tax income greater than $99,999 were less likely to desire the status quo be maintained (46% compared to 52% of those with an annual pre-tax income less than $100,000)
The shift between the earlier asking of the question (51% status quo) and the later SIMALTO stage (48%) was minimal but shows that in the context of the average annual bill and the costs of the other initiatives proposed, a few (3%) shifted from the status quo to preferring a planned amount – prioritising bill certainty in the big picture. Interestingly, this was the only shift in this direction observed between the individual and simultaneous testing of initiatives – every other initiative lost support in the simultaneous stage.
Two thirds of Melburnians (66%) agree that the desalination plant will be increasingly necessary in the future, while nearly half believe we should run the plant year-round to top up the dams and keep our water storages high. But there is a tension here – 43% also agree we should use the desalinated plant only when necessary (Figure 5).
Figure 5: Opinions on desalination
Bill payers aged 18-34 are more likely to prefer a more predictable bill even if it’s a little more expensive (55% compared to 41% over 34), while bill payers in high SES areas are less likely to agree that the desalination plant should be run year round (41% compared to 52% of other bill payers).

Figure 6: Perceived benefits from including a planned amount of desalination
The survey showed that stable predictable bills (selected by 45%) and water security (41%) were the main benefits that Melburnians felt would flow from including a planned amount of desalinated water in their bill (Figure 6). A quarter (28%) felt that more water for the environment and more water for us all to use (26%) were important benefits. Bill payers aged 18-34 were more likely to identity more water for the environment (36% compared to 24% of bill payers aged 35+) and it being the responsible thing to do (28% compared to 17% of older bill payers) as benefits.
In the qualitative focus groups, participants had indicated they felt – given Melbourne’s water security issues – that the water, if paid for up front, should be produced regardless of whether it was actually required or not.
When asked in the quantitative survey – more focussed on bill certainty than water security, there was a clear preference for reducing the following bills where the water was not required (Figure 7), however bill payers aged 18-34 were more likely to expect water to be produced even if it wasn’t needed (32% compared to 23% of older bill payers).

Resource recovery
Recycled water
Waste and recycling / re-use are currently having a “moment” in Australia – it’s not surprising that this topic was of strong interest across the sample; and that Melburnians are shocked to learn that we aren’t recycling more.
Broadly, the idea that Melbourne could and should be recycling much more water found very strong levels of support across the group discussions, with most reframing it as both a responsible waste use and a water security issue. Melburnians are surprised that more water isn’t being recycled – and they wondered why, and whether, in a dry continent like Australia, we can afford to let water that could be re-used go to waste when it could be safely used for non-drinking purposes.
Inevitably, some in each group brought up using recycled water for drinking, noting that it is done in other countries. This tended to have a more polarised reaction – it was usually only one or two in each group who were strongly supportive of recycled water being used for drinking purposes (noting that this was not brought up in the pre-reading pack) and most were ambivalent or strongly opposed to the notion.
“And I thought it [recycled water] would be used for drinking.” Male, 25-35, located within South East Water’s region
“But haven’t we got the best water in the world – why would you want to drink recycled water?” Male, 60+, located within South East Water’s region
“My concern is whether having dual systems is efficient. While it is wasteful to use drinking water to flush toilets, would that be an issue if we recycled water to a point where it was drinkable? Male, 60+, disability, located within Yarra Valley Water’s region
When the relative expense of recycled water was brought up (that is, the fact that recycled water is more expensive than desalinated water), our relatively low levels of recycling made more sense to participants. However, even when this greater cost is considered, most across our groups felt we should be recycling more.
People who frame water recycling as the natural endpoint or optimal way to manage human waste are most convinced of the worthiness of paying for water recycling. For these people, water recycling is emotive, it’s about ‘doing the right thing’ with our waste, cleaning up after ourselves properly.
When presented with options for increasing investment in recycled water, many people across the groups were willing to pay to see a doubling in the level of water recycling – which was how they interpreted the option presented to them (i.e. from 8% to 20% of our water recycled). However, the range they were willing to pay varied widely, ranging from $5-25 annually.

“So where does all that water go then?” Male, 25-35, located within South East Water’s region
In the online survey, participants were presented information about Melbourne’s current level of water recycling, and the costs and benefits of recycled water - including that it does not operate on a cost-recovery basis, but is instead subsidised through the sewerage charge.
Despite this clearly spelled-out cost disadvantage, a slim majority of Melburnians (56-59%) would be willing to pay an additional $5.49 per year to fund the construction of new recycled water systems from the Eastern Treatment Plant to supply an additional 5 billion litres of water.
Figure 9: Recycled water options presented in quantitative survey
Not surprisingly, the survey found very strong levels of agreement (74% net agree) that we should recycle as much water as possible from our sewerage system. Fewer (52%) are happy to pay more to ensure our waste is fully recycled, but bill payers aged 18-34 were more likely to agree with this (61% compared to 47% of those aged 35-54 and 49% aged 55+). Very few (13%) agree that our treated waste should not be recycled and should continue to be released into the bays.

willing to wear costs associated with greater water recycling – 61% of those aged 18-34 agree that they’re happy to pay more to ensure waste is full recycled, compared to 47% of those aged 35-54 and 49% of those aged 55+.
These finding echoe qualitative groups with older Melburnians (50+), which tended to focus more on the idea that recycled water should pay for itself (costs paid by users, such as councils who purchase water for sports ground watering). Participants argued rationally - and were largely convinced - that if recycled water costs more to produce than users are willing to pay, then Melbourne Water should not pursue greater levels of water recycling. Younger groups (Under 35) framed it with a waste reduction and climate change adaptation lens, and more clearly articulated it as an investment in their future, and the responsible thing to do.
The quantitative data shows the most widely perceived benefits from increased investment in water recycling are that (Figure 11):
It means our waste is fully treated, reducing effluent into the bays (38%) It puts our waste to good use (34%) It would help conserve the existing drinking water reserve (33%)
In line with findings outlined above, younger bill payers (18-34) are also more likely to see helping to manage the impacts of climate change as a benefit (33% compared to 23% of those aged 35-54 and 14% of those aged 55). Those aged 55+ were more likely to list:

aged 18-34) Not using valuable drinking water for parks, sports grounds, etc. (40% compared to 25% aged 18-54)
Highlighting a key difference in the way the benefits are framed, males are more likely to nominate improved water security as a benefit of increasing investment in water recycling (27% compared to 15% of females), while females are more likely to identify helping to manage the impacts of climate change (27% compared to 19%).

Stormwater harvesting
Melburnians across all group discussions were strong supporters of increased investment and focus on stormwater recovery and recycling. Many felt this was a priority area for investment – that letting stormwater go into the bays (and using potable water for watering ovals, etc.) is wasteful, and that we should be collecting and using more stormwater throughout the year. These sentiments were particularly strong among those who witness flooding of streets due to what they consider to be inadequate systems. The visibility of the ”water waste” made this option particularly compelling.
The idea that it could be used directly on sporting grounds and gardens found strong and intuitive support throughout the groups, participants appreciated the difference water can make to their local environments – providing better liveability across the city.
“I was surprised they weren’t doing a lot of those things already – like the stormwater thing, especially,” Female, 25-35, located within South East Water’s region
“I had no idea the runoff from hard surface – the impervious surfaces was such a problem – not something I was aware of!” Male, 25-35, located within South East Water’s region
Although not specifically presented in the options pack for group discussions, the idea of using more stormwater was broadly seen as one of the best options for increasing Melbourne’s water security and ensuring that our open spaces remain green and lush throughout summer without impinging on potable water supplies.
In the quantitative phase, survey participants were presented with Melbourne Water’s current level of stormwater harvesting (2.7 billion litres) along with a short blurb describing the benefits in terms of conserving drinking water, and allowing us to keep parks and gardens green over summer.
Three options were proposed to participants: maintaining the current approach ($0), compared with increases in the investment into stormwater harvesting at price points of $2 and $4 per year as detailed in Figure 12.
Figure 12: Stormwater harvesting options presented in quantitative survey
Increasing the amount of stormwater harvesting was the most positively received and strongly supported of all the initiatives included in the survey – only a quarter (24%-25%) opted for maintaining the current arrangements, while three-quarters opted for additional investment. Those more willing to pay for greater stormwater harvesting including:

Bill payers in high SES areas (79%, compared to 74% in medium SES areas and 72% in low SES areas)
Bill payers in higher income households (82% of those with an annual pre-tax household income greater than $149,999 compared to 76% of those with an annual pre-tax household income less than $150,000).
Notably, the proportion who selected the highest investment option ($4 per year) reduced significantly when all survey options were tested simultaneously, but the proportion supporting no change barely shifted.
In accordance with this result, Melburnians almost ubiquitously (85%) agree we should be harvesting as much stormwater as possible (this was higher among bill payers aged 55+, at 92%), and nearly two-thirds (62%) agree they are happy to pay more to allow greater harvesting of stormwater - implying that 13% who would pay for it, aren’t happy about it! Those aged 35-54 were the least likely to agree that they’re happy to pay more to allow greater harvesting of stormwater (53% compared to 68% aged 18-34 and 66% aged 55+).
Fewer (46%) could agree (and only one in eight (12% could strongly agree) they were previously aware that stormwater is captured and re-used – highlighting an important knowledge gap on a strongly supported activity.
Figure 13: Opinions on stormwater harvesting
The benefit from stormwater harvesting most likely to be selected by Melburnians was the conservation of existing drinking water supplies (52%). Reducing stormwater runoff into the bays (40%) and the improved water security (36%) that would allow us to keep parks and gardens greener during dry times (35%) were also more likely to be seen as important benefits.
Those aged 18-34 were more likely to nominate managing climate change as a benefit (40% compared to 30% aged 35-54 and 20% aged 55+), while those aged 55+ were more likely to list:

Biosolids re-use
Few Melburnians in group discussions were aware that biosolids are created from our sewage stream, or that there is currently a stockpile of around 20 years’ worth of biosolids. Across our discussions, people were shocked (if not horrified) that such a large amount of biosolid could be amassed without them hearing about it, and were surprised that these weren’t re-used as a standard practice for managing the sewage waste stream.
“I did wonder why we’ve got 1.6 million tonnes stockpiled – why isn’t it used every year?” Female, 25-35, located within City West Water’s region
While for some, discussion around biosolids could create an instinctive reaction of disgust, most across our groups clearly indicated that they supported the wider re-use of biosolids, and wondered why they weren’t being used more. All were confident that Melbourne Water would undertake rigorous testing to ensure there was no risk with the use of this waste product.
“I’m going to stop flushing my cat’s poo down the toilet now.” Female, 35-59, located within Yarra Valley Water’s region
When the costs of re-use were raised in explanation, some across all groups (but especially Melburnians 50+) tended to make the argument that their bio-solid re-use should pay for itself, and found it hard to believe that it wouldn’t currently do so. People instinctively felt that commercial solutions – including using bio-solids for power generation and direct on-land application could easily be found (and assumed that this is already happening in more progressive/innovative countries overseas). They imagined their waste was valuable, and that this value should at least offset the costs to extract it.
“I’d really like to see it used, but I feel like it should be the end-users who pay for it – can like Coles or whoever’s buying it off the farmers pay for it? I know we’ll pay for it the end, but I feel like it should be more direct.” Female, 25-35, located within City West Water’s region
This again demonstrates the principle of universality – people don’t want to see individuals benefitting (for e.g. a farmer, or land developer) at their expense.
When presented with options for greater biosolid re-use (Figure 15), groups were divided – many wanted increased use, but the amount of re-use they were willing to pay for was contentious.
Figure 15: Biosolids re-use options provided in group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
However, when pushed to accept that commercially viable solutions to bio-solid re-use were not currently available, and that re-use would require additional investment on their behalf – both to find and test alternative solutions, and to develop existing approaches such as direct land application – most asserted that they were willing to pay between $3-5 to ensure their waste was fully re-used and recycled, and wasn’t creating an ongoing issue.

“We have to do something about it, it can’t just keep piling up there, and somebody’s gonna have to pay for it and I guess it’s gonna be us.” Female, 25-35, located within South East Water’s region
Similarly to recycled water, when framed more as being the natural endpoint of the sewage treatment process – that is, when re-using biosolids is seen as part of the whole process rather than something that happens after sewage treatment – people across the sample were more supportive of paying to move biosolids off the stockpile.
“Yeah I feel better about when you say you get charged for sewerage treatment anyway.” Female, 25-35, located within City West Water’s region
In the Assess Phase, online survey participants were presented with the current biosolids situation – the rate of production, the size of the stockpile and current re-use activity. Results from the survey suggest that a majority (54-64%) of Melburnian bill payers are in favour of greater re-use of our biosolids (Figure 16).
Figure 16: Biosolid re-use options presented in quantitative survey
Notably, there was a significant difference when this was tested (and the cumulative impact on bills noted) simultaneously, with the proportion opting to meet the minimum EPA requirements increasingly substantially (from 36% to 46%) in the later SIMALTO test. The proportion opting for the greatest investment level also dropped significantly (from 40% to 27%). This pattern suggests, that while quite strongly supported, biosolids re-use is seen as a lower order priority when compared with the other initiatives.
Bill payers aged 18-34 are more likely support greater re-use of biosolids (72% compared to 56% aged 35-54 and 64% aged 55+, when tested alone).
Attitudinally, bill payers are strongly supportive (80% agree) of research into biosolids re-use, as well as re-using and recycling as much as possible (74%). In line with the willingness to pay observed above, just over half (52% agree) are happy to pay more to facilitate increased use of biosolids; just under half (49%) are happy to pay more to facilitate research into biosolids re-use. A third (34%) feel that sewage customers should not pay for research into re-use of their biosolids (Figure 17). Bill payers aged 55+ are more likely to agree that we should be researching how bio-solids could be re-used (86% compared to 76% aged 18-34 and 77% aged 35-54).

Notably on these willingness-to-pay questions there is a large neutral segment (28-30%) – who aren’t sure and probably would not be strongly opposed to additional costs, while a smaller proportion (20%) would definitely not be happy to pay more.
Putting our waste to good use (57%), ensuring it’s fully treated and re-used (51%) and the benefits to famers (48%) were the strongest perceived benefits from greater investment into re-use opportunities (Figure 18).

Access to open space and recreation
Melburnians clearly value our city’s beautiful and expansive gardens and outdoor spaces. Open spaces are one of the defining features of our city, and an aspect that clearly sets it apart. However, it was clear from the discussion groups that Melburnians do not necessarily believe that Melbourne Water has a large role to play in developing these, and on balance, if it means they will see a significant increase in their water bills, they would prefer Melbourne Water remains focused on priority areas that align with its core business.
Reservoirs
Many across our groups support a range of recreational uses around the “downstream” reservoirs as is already the case. Some can imagine a case for opening up the reservoirs further, including allowing people to recreate in the water. They imagine themselves using the areas for camping, fishing and kayaking, and that having access to previously inaccessible, pristine natural environments could only be a good thing – both for themselves and for any other Melburnians who would like to visit.
“Why not open them up, let people use them, if it’s just a little bit of work needs to be done – it’s not just walking tracks, it’s kayaking, it’s multi-use, for everyone.” Female, 25-35, located within City West Water’s region
But, in tension with this, people are concerned about water contamination, increased fire risk or even acts of deliberate terrorism becoming more likely if our pristine catchments and reservoirs are opened further to the public. For these people, the risks outweigh the benefits. They reason being that if Melburnians have done without access to these areas so far, then few would mind if access continues to be restricted.
“We already have enough open spaces for people to use – why would you risk potentially contaminating [the water supply].” Female, 25-35, located within South East Water’s region
As with other qualitative options, the costs attached to each option were not provided, and participants were asked to nominate what they felt
Figure 19: Recreation and open space options provided in group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
When the conversations turned towards what people were willing to pay for the necessary upgrades to allow safe opening of the reservoirs (options presented in Figure 19), only a minority were willing to contribute via their water bill.

“I think it should be encouraged, bushwalking, fishing and other things – it’s all good, but as long as there’s no impact on my bill.” Female, CALD, 25-35, located within City West Water’s region
“They should stick to their core business.” Male, 60+, located within Yarra Valley Water’s region
People were much more comfortable with such an initiative being paid for out of general tax revenues. This is an interesting tension: while the overlap between taxpayers and water-bill payers is undoubtedly high, on balance people felt it was fairer if the costs involved in opening up catchments were borne by the former rather than the latter.
For the online survey, the stimulus for this section outlined the commitment of the Victorian government to enhancing the recreational values of water, including increasing recreation on some of the state’s water storages - opening up two reservoirs for additional recreation activities.
Bill payers were presented with five options of additional funding for open space and recreation in the initial set and four in the SIMALTO to help explore the broader level of support and opposition – and the relationship to cost (Figure 20).
Figure 20: Open space and recreation options presented in quantitative survey
Results suggest that bill payers are broadly supportive of investment in increased recreation, with six in ten (62%) willing to bear some additional cost – although more than half of these supporters (35%) selected the minimum level of additional investment ($0.75 per year). Bill payers aged 18-34 are more likely to support paying for this option via their water bill (61% compared to 52% of those aged 35-54 and 53% of those aged 55+).
Interestingly, not all those who previously said they supported the option but didn’t want to pay selected the ‘don’t support’ option in the SIMALTO. Some decided, looking at the whole annual bill, that they would be prepared to bear a small cost – and the overall proportion not prepared to pay decreased.
Melburnian bill payers broadly recognise (62%) the community benefits of recreation in and around Melbourne’s reservoirs, even if they are less likely to make use of the increased recreational opportunities in and around reservoirs themselves (41%, 49% for those aged 18-34 ) and be happy to pay for it (39%) (Figure 21). That Melburnians are less ‘happy to pay’ for increased access to open spaces than recycled water (52%), biosolid re-use (49%) and stormwater(62%) harvesting supports the notion that they are more likely to see this as outside their responsibility as water bill payers.
A substantial minority (29%) don’t like the idea of increased community recreation in water reservoirs (such as fishing, boating, kayaking), and a similar proportion (26%) are opposed to increased recreation around reservoirs, like picnics and bushwalking.

Figure 21: Opinions on open space and recreation
For those opposed to increased investment in open space and recreation, the potential for contamination to our water supply was the most commonly selected reason for their opposition (41%), with the cost not seeming worth it, and the potential for harm to existing ecosystems also key issues.

Pipetracks
While few had any objections to the idea of opening up pipe tracks – and most felt that it is an idea with merit – almost everyone across the group discussions felt that those more likely to use these areas are those who live nearby, and that they should shoulder any costs required to do so. They felt that local councils should take responsibility for the land in their areas, including making it suitable for recreation and commuter use.
This means that from a willingness-to-pay perspective, pipe tracks within Melbourne were much less polarising: few were willing to pay for these. Part of this response may be about the visibility of pipe tracks – there weren’t many across our sample who aware of any such land near to their homes or workplaces, and this lack of awareness underpinned their lack of support for such opening up of the land – the options presented to them (Figure 24) did not appeal strongly.

If the use of pipe track development would create bike paths that were more than just recreational (i.e. worked in with the public transport system, or allowed for easier riding to work, etc.) then the perceived value of this initiative increased. For some, the potential additional cost of 4 cents was so low that the topic become redundant, with many declaring it should just be done and not even discussed.
“Just do it and don’t tell anyone.” Female, 60+, Ringwood, located within Yarra Valley Water’s region
Building from the group discussions, quantitative stimulus for investment in pipetrack shown to survey participants provided an overview of the opportunity pipetracks offer to connect open spaces with linear green corridors, and the fact that the improvements would occur in several locations across Melbourne.
Three options were presented to participants, outlining different co-investment approaches to opening up pipetracks, including Melbourne Water providing land only ($0), and options for 6.5km and 12km of improvements costing $0.04 and $0.50 per annum (Figure 25).
Although bill payers revealed the strongest preference towards pipetrack investment of any of the initiatives initially, when considered amongst other options simultaneously, their enthusiasm waned. When tested individually, more than three in four (78%) bill payers were in favour of contributing at least an extra $0.04 per year on their water bill. When this option was considered amongst other initiatives, the proportion who supported no capital funding increased ten percentage points; indicating that that a substantial proportion balked at the (very small) additional cost when looking at their overall total, and trading-off against other initiatives. Despite this dynamic, pipetrack investment has very strong levels of support overall.
Figure 25: Pipetrack options presented in quantitative survey
Around seven in ten (69%) Melburnians support the notion that Melbourne Water should make as much land as possible available for recreation, and half (55%) are happy to pay for it. (Figure 26). However, bill payers are split on who should bear the costs of pipetracks investment – 31% think that not only local residents who benefit from this land should pay (33% are neutral, and 36% agree) – echoing a sentiment which was more commonly expressed in group discussions.

Sewerage system
Resilience
Although sewerage is clearly something most Melburnians take for granted as an almost invisible component of their day to day life, they also clearly recognise its fundamental importance, and do not like the idea of a degraded or inferior system incapable of handling Melbourne’s growth and development. A leaky or unsound sewerage system is not a risk that Melburnians are willing to take, and when it is explained that the sewerage system has infrastructural elements that are hundreds of years old, most participants agreed that were willing to invest in its ongoing function and longevity.

Participants across our group discussions were strongly supportive of the options provided for greater investment in ensuring our sewerage system is resilient and ready for the future challenges of population growth and climate change (Figure 28).
Figure 28: Sewerage system resilience options presented to group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
A few participants questioned why they were being asked to invest further now, at this particular moment, wondering why the level of investment and the costs they incur on their water bills to cover sewerage disposal and treatment aren’t enough to cover proper management of the sewerage system. They reasoned that Melbourne Water should have been including the full costs of maintenance in the sewerage charge over time, rather than needing to ask for additional funding now. Some deemed the request for additional funding an apparent failure of effective planning and foresight.
However, regardless of whether they viewed the needs for greater investment as a failure or just a fact of life, virtually all in group discussions were prepared to pay in the order of $10-20 to ensure Melbourne’s sewerage system remains robust and resilient to future needs.
Survey participants were presented stimulus about the sewerage system, detailing its importance, its age, and the notion that if not upgraded, pressures imposed by population growth and climate change could risk spillage into the environment.
Bill payers were shown three options for increasing sewerage system resilience – maintaining the current approach ($0) compared to Melbourne Water investing an additional 1% or 2% of total sewerage system capital costs ($0.31 and $0.60 per annum added to their bills respectively) (Figure 29).
Overall results suggest that Melburnians see strong value in the options to improve the current sewerage system – three quarters (72-76%) were willing to pay additional costs on top of their water bill, while the remaining quarter (24-28%) opted to maintain minimum renewals and upgrades. Notably, in the final simultaneous trade-off, sewerage upgrades found the second-highest levels of support for additional investment, behind only stormwater harvesting. This flags sewerage resilience as a priority issue for bill payers.
When this topic was tested alone, bill payers aged 35-54 were less likely to support more than the minimum investment (71% compared to 77% of those aged 28-34 and 79% of those aged 55+).

The majority of bill payers are in support of ensuring that the sewerage system is fit for future generations (87% agree), prepared to cope with a growing population (87%), and that investments should be made for the long term (86%). While many agree that it is a good investment, bill payers are hesitant to pay out of their own pockets for future repairs and upgrades – around six in ten (59%) are happy to bear additional costs (Figure 30).

Agreement with the above statements varied across age group. For example, younger bill payers were more likely to agree that upgrading Melbourne’s sewerage system is a waste of money (16% of those aged 18-34 agreed, compared to 12% of those aged 35-54 and 3% of those aged 55+). This may be the result of older Melburnians being more aware (via stories passed from older generations) of the city’s struggle with odour before being connected to a sewerage system in the late 1800s – an issues which earnt Melbourne the dubious

Feeling that it’s worthwhile paying extra to ensure there are no problems with the sewerage system (78% high SES compared to 65% low SES and 72% medium SES).
Health related benefits and long-term planning and use were perceived to be the most important benefits of increasing investment into Melbourne’s sewerage system (Figure 31).

Odour management
The issue of odour was contentious. Not all were willing to accept that odour is an issue – and some argued vigorously that there aren’t really additional odours associated with the treatment plant. In addition, for many across our groups, odour issues are not a personal problem, but an issue strictly for those who live in affected areas.
Groups consistently brought up the argument that if people had bought houses near treatment plants or sewer vents then they would have “known what they were getting themselves into”, and potentially would’ve paid a lower property price than if the area wasn’t subject to the odour. Those who saw it this way felt that where the need for odour management arose from a pre-existing plant and equipment, then they would not be prepared to pay for that.
“I know it sounds savage, but if they bought into that area [with an odour] then that’s on them, they probably bought in cheaper because of it.” Female, 25-35, located within South East Water’s region
Some framed the issue with a broader perspective – bringing up the importance of citizen and city-wide health, the need to ensure a high degree of sanitation, and the value of providing a good quality of life across the full community.
Options provided to participants in group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
There was some consideration that with Melbourne’s continued growth odour may not remain restricted to outer areas and could easily become their problem in the future. Others imagined what it would be like for workers and tourists if the CBD started to smell like a sewer. For these citizens, poor odour was associated with developing world cities and something to be avoided. When these perspectives were raised, there was a far greater willingness to invest in effective odour prevention.

No questions pertaining to odour management were included in the online survey.
Carbon offsets
Carbon offsets are not necessarily a well understood topic – some people required a great deal of explanation in addition to the reading pack to digest the information and consider the options (Figure 32).
“To be honest, I’m not really sure what a carbon offset is.” Male, 35-59, located within Yarra Valley Water’s region
Figure 32: Carbon offsets options presented to group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
In addition, the idea of carbon offsets can be contentious. Age divides the community on this topic, with many of those in older groups more distrustful of offsets, and less likely to favour rapid offsets if at all.
Those in younger (25-35) groups, mostly settled on the most rapid carbon abatement offered in the selection
(100% by 2021), willing to incur the additional costs. They fully accepted the need to offset CO2 production.
They indicated that offsetting was the responsible thing to do while working towards zero-carbon
operations, and the additional cost of high-benefit local offsets seemed reasonable to them. For these
groups, an additional $7-10 per year, starting in 2021 to 100% offset the carbon dioxide equivalents

do.
“Look, I don’t think we can do enough on climate change. I’d be happy to pay the top rate.” Male, 25-39, located within City West Water ‘s region
Older (50+) groups debated the overall need for abatement. But despite their hostility towards offsets, only
a minority believe Melbourne Water has no responsibility to manage its greenhouse gas emissions; and a
majority were supportive of investing in plant and technology that helps achieve this. For these groups, the
minimum approach to offsets found more favour – they were less willing to speed up the offsetting of carbon
dioxide ahead, or in excess of, the government’s targets. These groups also included a few climate-change
deniers, or those who do not believe that humans can do anything about global warming - for those
participants, any level of offset that meant they incurred additional costs were outright rejected. This meant
that the average willingness to pay among these groups was considerably lower.
Among both younger and older groups, there was a preference that Melbourne Water become more energy efficient, rather than needing to buy offsets.
This sentiment was echoed in the quantitative research - more than half (57%) of bill payers prefer that Melbourne Water reduce its emissions rather than utilise carbon offsets (Figure 33). However, Melburnians clearly lack a detailed understanding of carbon offsets with half (52%) of bill payers not sure whether carbon offsets are a good way to reach net zero. A third (33%) agree that they don’t really trust offsets, but half (51%) aren’t sure whether they trust them or not.
This poor understanding leads people to be suspicious of offsets and carbon accounting. Group discussion participants felt that offsets could seem like a sleight of hand, and there was nothing offered in the information pack to suggest that accounting standards are robust or monitored. The most suspicious were far less supportive of offsetting any faster than was necessary, based partly on this distrust – especially in relation to overseas initiatives.
“I’d like to see them not just looking at carbon offsets but at mitigating in the first place. Looking at where they can add renewables into their business. Otherwise they don’t have any incentive to change their behaviour. They’ll just keep to the status quo.” Male, 25-39, located within City West Water’s region

For example, bill payers aged 18-34 were more likely to agree that they’re not really sure how carbon offsets work (55% agreed compared to 46% aged 35-54 and 44% aged 55+). Interestingly, this poorer understanding did not translate to a decreased desire to see Melbourne Water utilize carbon emission – 43% of bill payers aged 18-34 agreed that carbon offsets are a good way to reach net zero in the short term (compared to 37% aged 35-54 and 24% aged 55+). Those in this age group were also more likely to agree that they would support Melbourne Water to reach net zero emissions earlier than 2030, even if it cost them more (58% agree compared to 51% aged 35-54 and 38% aged 55+).
Other key demographics are detailed below:
Those aged 55+ were more likely to agree that they don’t trust carbon offsets (40% agree compared to 28% aged 18-34 and 30% aged 35-54)
Bill payers in lower income household were more likely to agree they’re not really sure how carbon offsets work (54% with an annual pre-tax household income up to $60,000 agreed, compared to 43% of other bill payers)
Billy payers from higher income household were more likely to support Melbourne Water to reach net zero emissions earlier than 2030, even if it cost them more (62% with an annual pre-tax household income greater than $149,999 agreed, compared to 47% of other bill payers)
Bill payers within South East Water’s region are less likely to support Melbourne Water to reach net zero emissions earlier than 2030, even if it cost them more (43% compared to 52% of bill payers in other regions)
Online survey participants were shown stimulus about Melbourne Water’s goal to halve greenhouse gas emissions by 2025 and given a description of the benefits of carbon offsets. They were also shown options to reduce emissions by 50% by 2025 or by 2021, and fell under the categories of ‘Basic global’, ‘High benefit global’, ‘Basic local’, and ‘High benefit local’ (Figure 34).
Carbon offsets were probably the most polarising items included in this survey – Melburnians tended to select either the highest cost, ‘high benefit local’ (34%) or lowest cost ‘basic global’ (37%) options.

Males were more likely to prefer basic global offsets than females (33% vs to 27%), while females were more likely than males to prefer high benefit local offsets (44% vs to 34%)
Bill payers aged 18-34 were more likely to prefer
Those located further than 10km from the city were more likely to preference basic global offsets (32% compared to 25% of those living within 10kms of the city)
Bill payers living in low SES areas were less likely to prefer high benefit local offsets (32% compared to 41% of bill payers in medium or high SES areas)
In line with a higher endorsement for high benefit local carbon offsets, Melburnians are in strong disagreement (43%) that Melbourne Water should prioritise international benefits over local benefits (Figure 35). Additionally, around three in ten (32%) bill payers remain neutral regarding choosing between international and local benefits, possibly highlighting a lack of understanding around carbon offsets.
Figure 35: Opinions on carbon offsets
Males were more likely to preference international over local benefits (29% agree compared to 22% of females), while females were more likely to prefer pursuing carbon offsets that offer the greatest additional social or environmental benefits (67% compared to 59% of males).
The perceived benefits of purchasing carbon offsets most likely to be selected by Melburnians was to minimise harmful impacts on the environment (43%) as well as to provide one of many avenues to tackle the issues of climate change (36%) (Figure 36). Compared to most of the other options, a larger proportion of Melburnians are likely to not view any benefits of carbon offsets (15%).

Managing runoff from surfaces
Melburnians have not heard about – or considered – the issues with increasing impervious surface area and development across the city – just one in five (21%) bill payers were that impervious surface area growth is major and growing challenge for waterways and bays. However, the issue makes intuitive sense to them once they have read or heard about it – few needed further convincing of the challenges.
Figure 37: Impervious surface area options presented in group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
For many, this initiative was considered a “surprising fact”, compelling them to reflect on their own environments. One woman noted that she would have chosen a different driveway design if she had been made aware of the implications. Another noted that she no longer resented the small patch of lawn that she has to manage and had been considering removing, now she understood its value. Some were aggrieved by the fact that they had little control over the extent of impervious surface in their home – they felt that if they were more aware of the problem, they could contribute in other ways.
“I’d never heard about it. This was the most interesting thing I learnt.” Female, 60+, located within City West Water’s region
Across our sample, many felt that the flat charge for impervious surfaces was unfair. The sense of unfairness stems from the fact that larger and smaller properties, as well as properties with entirely impermeable surfaces and those with entirely permeable surfaces, are all charged at the same rate. People reasoned that those with larger impervious surface areas are more likely to be bigger businesses. Across groups, the notion of a small local retailer or office paying the same rate as a large suburban shopping centre or supermarket with acres of carpark seemed ridiculous. Hence, the proposed flat charge appears to penalise smaller property owners and benefit those with larger land area – with the outtake that those who are worse off pay relatively more (a regressive tax).
“So you’ve got small households like me and small businesses like the fruit shop over there and we’re paying virtually the same as Chadstone. How does that even make sense?” Female, 60+, located within Yarra Valley Water’s region
People also felt that the flat impervious surface charge is likely to be ineffective at reducing impervious surfaces across our city. The flat charge approach, we were consistently told, does not provide an incentive to do the

right thing and won’t encourage businesses to minimise runoff from their properties. They rejected the idea that the flat charge is a tool to ‘manage the growth of impervious surface area’ as presented in the options pack.
“It just doesn’t make sense! A flat charge isn’t going to encourage people to change behaviour. I think they must have got it the wrong way round.” Male, 25-39, located within City West Water’s region
Overall, people felt that businesses with larger properties and more impervious surface areas should pay more. They recognised the challenges (and administrative cost) involved in calculating charges based on impervious surface area, however they reasoned that rates charges based on land area and this would be an acceptable substitute on which to calculate an impervious surface change.
Further, there was strong sentiment that developers – those who have relatively more control over the growth of impervious surface area – should be made more accountable for their decisions in this regard (even if any charges made on developers would inevitably be passed on to the buyers). Others discussed alternative solutions to a charge, including more effective regulation – ensuring development is responsible, for example, and that developers use materials and designs that minimise the problems.
In the quantitative survey, participants were presented information about the current costs for both residential housing and businesses in managing stormwater runoff. Participants were shown two payment options – the current fixed flat charge model and an alternative ‘user pay’ approach.
In contrast to the group discussions, more than half (56%) indicated a preference for Melbourne Water to continue with the current flat charging model for impervious surface area, while 44% support the proposal to investigate moving to a ‘paying for your impact’ charging model (Figure 38).
Figure 38: Waterways and drainage service options presented in quantitative survey
This apparent contradiction with the discussion group findings could be explained by the differences in information presented to participants – those completing the survey saw a balanced list of pros and cons for the initiative that stated there would be little difference in most cases, and that there would be some costs associated with the change. But it could also be explained by the more detailed examination of the issue in the focus groups, and the invocation of ‘fairness’ in discussions of the ‘pay for your impact’ model and social desirability bias.
Those more likely to be in favour of moving to a ‘paying your impact’ model include:
Bill payers living in the inner city, but not the CBD itself, (53%, compared to 44% living in the CBD and 42% living greater than 10km from the city)
Bill payers living in high SES areas (49% compared to 41% in low SES areas and 42% in medium SES areas)
Educating Melburnians
Melburnians are highly supportive of greater investment in water education. After absorbing the pre-reading pack and discussing Melbourne’s water supply and management options, virtually all participants felt there was a need for ongoing communications informing Melburnians about the water system, Melbourne Water’s work, and how they can help by being better citizen-users of our water resources. They also felt that Melbourne Water

should be informing Melburnians about any of the initiatives they were exposed to through the research process – like for example water recycling, stormwater reuse and biosolids.
“I think the education should be done over many mediums. Things like social media, tv, radio, newspapers, website's, etc. Making it jump out at people.” Female, 35-59, disability, located within South East Water’s region
“Once you know more you can be a bit more mindful. It’s important.” Male, 25-39, located within City West Water’s region
“To be honest, I’m not going to become any more water saving if they don’t give me a good nudge.” Male, 35-59, located within Yarra Valley Water’s region
“I personally feel that it's really important for Melburnians to know more about what Melbourne Water does and how, and how they can play a part. I kinda feel as though living in the city can mean we take water for granted, and don't pay much mind to how the water coming out of our taps actually gets there. I think an awareness of HOW it all happens could help people to better appreciate the process.” Female, 35-39, chronic Illness, located within Yarra Valley Water’s region
Participant preferences were to have this awareness built into public education through schools, but many felt this was, in and of itself, not enough. They reasoned that many older adult Melburnians would not have been exposed to any education on the water system in a long time, and that as one of the fastest growing cities in Australia, they felt that recent migrants from both other countries and other states of Australia may not know about the particulars of Melbourne’s world-class water system.
Hence, many felt that an ongoing, low-level campaign – via bills, highly targeted digital advertising, or project-specific outdoor signage – would be a useful way to build awareness of the scope of Melbourne Water’s activity.
“You don’t want them to spend a lot of money on advertising, but they should be keeping us in the loop. What they’re doing to keep the water supply up, what they are doing with the sewerage system.” Male, 35-59, located within Yarra Valley Water’s region
Western Treatment Plant access and ecotourism
Participants in group discussions were broadly supportive of the proposed improvements (Figure 39) to the visitor facilities at the Western Treatment Plant, and the relatively low costs involved when amortised across all Melburnians meant that only a few across the discussions were ultimately opposed.

Very few previously knew that the Western Treatment Plant was open for public access, or that it is a specialist bird watching area. However, with the exception of a few committed birders, there was a notable lack of enthusiasm about the idea and few could imagine themselves paying the centre a visit – it emerged as a lower order priority. Even the bird watchers in the sample were cautious about innovations that might encourage more people to visit the Plant. They imagined that people who weren’t as passionate as they were about bird watching might behave inappropriately – with the noise of increased crowds scaring away the birdlife that the area is prized for.
“You’d think I’d like it being a bird watcher. But more people aren’t necessarily a great thing. I know some people who would be really against.” Female, 60+, located within City West Water’s region
“I think an actual physical visit would perhaps have more impact, but if that wasn't always doable, a virtual tour could be great! Better that than nothing at all, I think!’” Female, 35-59, chronic illness, located within Yarra Valley Water’s region
“Although it isn't a bad idea, I think money is better invested elsewhere than into the facilitating visitation to Western treatment plant. I don't think this initiative would be accessible (or even interesting) to a lot of people, and I feel this knowledge can still be taught in a school/workplace/community setting. Perhaps a virtual tour on a website instead? This means there would be no interruption to the wildlife/native flora either.” Female, 18-34, mental health, located within City West Water’s region
Quantitative participants were shown information about access to and ecotourism of the Western Treatment Plant, and the costs and benefits of investment into education materials and visitor facilities. They were presented with two options:
To maintain the current level of ecotourism facilities at the Western Treatment Plant ($0 per year) To invest in additional ecotourism facilities to increase visitor capacity and improve visitor experience
($0.47 per year).

Overall results indicate that just over half (55%) of Melburnians support the proposal to invest in additional visitor facilities at the Western Treatment Plant while 45% believe Melbourne Water should maintain the current level of visitor facilities (Figure 40). Bill payers aged 18-34 were more likely to support additional ecotourism investment (63% compared to 52% aged 35-54 and 51% aged 55+).
However, when the options were tested simultaneously, these positions reversed, with under half (44%) contributing when tested simultaneously alongside other initiatives – substantially fewer Melburnians were willing to pay when considering the combined impact of their choices on their potential bill.
Despite half of bill payers agreeing that improving visitor facilities would be a worthwhile investment, fewer than four in ten (37%) would consider visiting the Western Treatment Plant, while 45% believe better facilities would make no difference to them personally (Figure 41). Those within City West Water’s region are more likely to consider visiting the Western Treatment Plan (46% compared to 34% living in other areas).

Water cycle education and awareness
Participants in groups discussion felt that the development of a range of digital education resources would be useful in helping people learn more about Melbourne Water’s work, the water cycle, and what they can do to help. They envisaged these would be useful in school classrooms, as teaching aides, and for the general public.
Figure 43: Education options presented in group discussions
N.B. for materials provided to participants in the pre-reading pack, refer to appendix.
But many wondered whether and how they would come across these without being specifically prompted by social marketing materials, and they consistently raised the idea of an ongoing advertising or marketing campaign and its capacity to broaden awareness and drive people to access resources.

“Yeah – I’d like to see a digital campaign that would tell Melburnians about all this stuff – it’s really important, and none of us really know about it” Female, 18-34, located within South East Water’s region
The sense of community action and communal spirit in saving water that information, education and campaigns can help foster was also discussed in positive terms. Many felt that the millennium drought brought the community together around a common purpose - and ultimately reduced water use substantially - but this sense of collective stewardship of our water resources had since diminished.
This meant that, across the groups, people were willing to pay a few dollars – between around $1 and $3 – for Melbourne Water to better inform Melburnians about its work, including both the development of digital resources and other forms of advertising to build broader awareness.
Survey participants were presented information about the current level of understanding by the community about what happens to water that has been used in homes and businesses. They were also shown different investment options for developing digital education programs and the building of interactive facilities (Figure 44).
More than half (57%) are supportive of the plan to invest in better education programs and facilities with one in five (21%) bill payers likely to take up the maximum level of additional investment - $0.78 per year (Figure 44).
When tested simultaneously, a similar proportion of bill payers supported each investment option.

SECTION B: WATER SECURITY AND BILL CERTAINTY
RANDOMISE SECTION B: TO SECTION B:
ASK ALL Bill certainty: We have heard that people prefer more predictable bills. Desalinated water order costs can have a noticeable impact on the level of bills. Desalinated water from the plant is ordered each year based on storage levels and predicted rainfall and water use. The order can be zero. Each time we order water, the cost is currently passed directly on to customers as an additional cost in their water bill. To minimise annual bill variations, your water bill could include an annual amount to cover the cost of expected desalination orders. This would create more certainty in the costs on your bill each year, instead of having a single full charge passed on when a water order is made. However, there will still be an increase over this amount if the order is larger than allowed for.
In five years from 2021, what option to pay for desalinated water orders would you support?
Three options for how Melbourne Water could manage billing of desalinated water are provided below. Please read each of these carefully and select the billing structure you would prefer Melbourne Water adopt. (SINGLE RESPONSE)
B.1.a Maintain current billing
arrangements for desalinated
water orders, passing on the
costs when orders are made.
No change to water bill
B.1.b Increase annual water bill
to include a planned amount of
$16 per year to cover the cost of
desalination orders, instead of
increasing prices when orders are
made.
This option is equivalent to a normal desalinated water order of 50 billion litres each year. Where orders exceed this
amount then a “top up” amount
would be added to your quarterly
bill. If no water orders were made
your bill would reduce.
B.1.c Increase annual water bill
to include a planned amount up
to $34 per year to cover the cost
of desalination orders, instead of
increasing prices when orders are
made.
This option is equivalent to a normal desalinated water order of 100 billion litres each year. Where orders exceed this
amount then a “top up” amount
would be added to your quarterly
bill. If there were no water
orders, your bill would reduce.

SECTION C: RESOURCE RECOVERY ASK ALL Resource recovery: water recycling Melbourne’s growing population and the impacts of drought and climate change create greater stresses on our ability to deliver a reliable water supply. Recycled water from the Eastern Treatment Plant (ETP) and Western Treatment Plant (WTP) can ease pressure on drinking water supplies and other water resources such as groundwater and creeks/rivers, and provide water security for a range of non-drinking uses. Recycled water is currently used for farming and irrigation, industry, firefighting, watering parks and sportsgrounds, and in toilets, laundries and gardens in new housing suburbs via “dual pipe” distribution systems. Recycled water is partially paid for by those who use it, with the “gap” paid for by sewerage customers. This “gap” is because the cost of treating and distributing recycled water is often greater than what recycled water customers are willing or able to pay. Recycled water can be more expensive than other sources of water that may be available such as ground water and surface waters such as stormwater and creeks/rivers. Under current arrangements, on average end users (e.g. irrigators) pay approximately 33% of the cost with the remaining 67% paid by sewerage customers. Currently around 8.4% of treated sewage flows are recycled, the remainder (91.6%) goes into Port Phillip Bay (WTP) or the ocean (ETP). More could be recycled (particularly from the ETP where there is ample supply available) however we would need to invest in building distribution capacity, and partner with a water retailer to deliver recycled water to new customers.
In five years from 2021, which option for recycled water distribution for Melbourne Water would you
support?
(SINGLE RESPONSE)
C.1.a Maintain current level of recycling at around
8.4% (27 billion litres of water per year) or increase it
if new customers are willing to pay the full cost of
recycled water production and distribution.
No change to water bill $0
C.1.b Fund the construction of new recycled water
distribution systems from the Eastern Treatment Plant
to provide capacity to supply an additional 5 billion
litres of water per year to customers (a 19% increase
in recycling on current levels).
Cost $5.49 per year paid by sewerage customers as
part of their water bill.

ASK ALL Water security – stormwater harvesting Melbourne’s growing population and the impacts of drought and climate change creates greater stresses on our ability to deliver a reliable water supply. Stormwater harvesting involves collecting, treating, storing and using stormwater runoff from urban areas. If stormwater is captured it can be used for a range of purposes (like sportsgrounds and industry) as a substitute for our drinking water. Capturing stormwater before it enters waterways also helps keep our rivers and creeks healthy. Melbourne Water currently reuses some stormwater (approx. 2.7 Billion litres). Much more could be captured and used if there was greater investment in infrastructure to capture and treat, taking the pressure off drinking water supplies.
In five years from 2021, which option for recycled water distribution for Melbourne Water would you
support?
C.4.a Maintain the current level
of water planning, education and
investment in storm water
harvesting water programs.
No change to water bill $0
C.4.b Reduce pressure on our
drinking water supplies by investing

ASK ALL Resource recovery- Biosolids reuse: Biosolids are the solid, organic material left over after the sewage treatment process. As part of treating your sewage, large amounts of biosolids – approximately 70,000 tonnes - are produced every year, and there are legacy stockpiles of around 1.6 million tonnes. In recent years Melbourne Water has explored various opportunities to re-use biosolids. Options range from spreading biosolids onto land through to fuel for energy production. Currently land application is the only viable option available to Melbourne Water while other re-use options may take a few years to investigate and implement. Presently most of the cost associated with biosolids re-use is associated with the transportation for land application. Melbourne Water has committed to meet a new Environment Protection Agency requirement for biosolids from our Western Treatment Plant (WTP), that will require re-use of at least 40% (or 16,500 tonnes per year) by 2025/26, and 100% by 2030/31. Presently there is no EPA requirement for the Eastern Treatment Plant (ETP), due to a recent large land remediation project which reduced ETP’s legacy stockpiles by over 1 million tonnes. In addition to land application programs Melbourne Water will continue to investigate new technologies, which have the potential to recover energy and/or nutrients from biosolids, for future generations. Melbourne Water could meet the minimum EPA re-use requirement at the WTP. Or it could invest in a higher level of re-use, building on increasing interest from local farmers and seeking large one-off re-use opportunities such as land rehabilitation, from both treatment plants. (Q4)- In five years from 2021, what option for biosolids reuse for Melbourne Water do you support? (SINGLE RESPONSE)
C.6.a Meet the Environment
Protection Agency requirement to
achieve 40% reuse by year
2025/26, and be on track to
achieve 100% reuse by year
2030/31, at the WTP.
No allowance for reuse from the
ETP.
Total reuse of 16,500 tonnes per
year.
Cost $0.62 per year paid by
sewerage customers as part of
their water bill
C.6.b Meet the Environment
Protection Agency requirement for
WTP as from Option 1, plus:
Allow for re-use from the ETP as
well, achieving an average level of
40% re-use across both plants.
Total reuse of 28,000 tonnes/yr.
Cost $1.14 per year paid by
sewerage customers as part of their
water bill
C.6.c Meet the Environment
Protection Agency requirement for
WTP as from Option 1, plus:
Also allow for one-off large scale
(opportunistic) reuse opportunities
for both WTP and ETP (e.g. land fill
rehabilitation).
The exact amount reused would
depend on the nature and location
of the large scale reuse
opportunities, but the cost impact
would be roughly equivalent to
achieving an average level of 50%
reuse across both plants.
Equivalent total reuse of 37,000
tonnes/yr.

SECTION D: ACCESS TO OPEN SPACE AND RECREATION ASK ALL Recreation & Open Space: Some of the land Melbourne Water manages is around water storage reservoirs. Recreation has been confined to reservoir parks down stream of the reservoir to prevent impacts on drinking water quality. The Victorian government is committed to enhancing recreational values of water, including increasing recreation on some of the state’s water storages.
To support that commitment, Melbourne Water have
investigated the costs and benefits of increasing
recreation activities at a number of reservoirs, and
identified two reservoirs where additional recreation
could potentially take place - if investments were
made in additional drinking water treatment and
other facilities needed to make them a nice, safe place
to visit.
These two sites, both within 110km of Melbourne
could provide the community with opportunities for
parklands, fishing, bushwalking, bike riding or
canoeing.

ASK ALL Recreation and open space Melbourne Water is the second largest landowner in Melbourne. There is increasing demand for public open space due to population growth. Melbourne’s transport network will need to cope with an extra 10.6 million trips a day by 2050 (almost double current). To accommodate this, the share of trips by public transport, walking and cycling must increase. Pipetracks – the land under which Melbourne Water’s pipes run - provide a linear corridor which often connect to surrounding open space. Before this land can be used by the community, it may need work to make it safe and protect the core services it supports – for example, fencing off valves and ensuring nothing is built on top of pipes. The land may also need improvement to make it an enjoyable community space, such as landscaping or installing educational signage. This type of work would be delivered in partnership with local councils and Parks Victoria. There is an opportunity to maximise these linear corridors as :
Linear parks for passive recreation
Active transport links
Green and shaded places for people and wildlife.
Places that improve the communities understanding of; MW’s role and history, local biodiversity
and cultural heritage values.
These pipetracks are all across our city and could benefit a wide range of Melburnians.

SECTION E: SEWERAGE ASK ALL Sewerage- Resilience: The Sewerage System has a key role in keeping Melburnians and the environment healthy through safe collection, transport and treatment of sewage across Melbourne. Our sewers need to be renewed and upgraded to prevent the otherwise high risk of sewage spilling into the environment. Some of our sewers are over 100 years old and many show considerable signs of corrosion. A warming climate and growing population will increase the impacts on our sewers. Going beyond just delivering minimum renewals and upgrades will help us to be prepared for the future and ensure that future generations have the same benefits from the sewerage system as we do. A sewerage system that can continue to provide a reliable service in the face of future challenges is the hallmark of a resilient system.
In five years from 2021, what option for increasing
sewerage system resilience do you support?
E.1.a Melbourne Water
continues to invest in minimum
renewals and upgrades to the
sewerage system which manages
risk to public health and the
environment but does not fully set
us up to meet future challenges.
E.1.b Melbourne Water invests
an additional 1% of the total
sewerage system capital costs in
greater than minimum renewals
and upgrades now to provide
greater flexibility to respond to
challenges such as population
growth and climate change in the

Melbourne Water | Pricing Submission 2021 Community Research | February 2020 page 76
Pt 1 As part of providing water and sewerage services to the residents and businesses in our city, Melbourne Water is one of the biggest emitters of greenhouse gases (including carbon dioxide) in Victoria. Most emissions come from two sources: the energy used to pump and treat sewage, and direct emissions from the sewage itself. Melbourne Water is required by the Victorian Government to halve emissions by 2025, and has a goal to achieve net zero by 2030. However, if customers are supportive, Melbourne Water could take additional action to reduce its emissions earlier than this. We will halve our energy-related emissions by improving energy efficiency and generating renewables. Reducing direct emissions from the sewage itself is more difficult, so in the short to medium term we will have to “offset” these emissions. In the long term we will need to make changes to our treatment infrastructure to reduce them.

Melbourne Water has pledged to halve greenhouse gas emissions by 2025 and aims to achieve net zero emissions by 2030. Like any product, not all carbon offsets are equal. Firstly, Carbon offsets can be purchased locally within Australia or internationally. Additional benefits of carbon offsets could also be realised with different approaches. This could include more trees for the forests and special landscapes in Australia - that also provides greater habitat for local threatened species - or local investments in renewable energy. Otherwise Melbourne Water could make these investments overseas in developing countries for example. To meet its obligations, Melbourne Water could purchase: • ‘basic’ offsets in cheaper overseas countries to meet its
targets,
• ‘basic’ offsets from Australian providers that meet
Australian standards
• ‘high value’ offsets that provide additional environmental and social benefits in other countries
• ‘high value’ offsets that provide additional environmental and social benefits in Australia
In the five years from 2021, what level of emission reduction do you support, and what type of
offsets should Melbourne Water purchase?
(SINGLE RESPONSE)
How quickly should we cut
emissions? Additional Benefits of Offsets
Purchase enough offsets to reduce direct emissions by 50% by 2025, as required by Government.

SECTION C: MANAGING RUNOFF FROM SURFACES ASK ALL
Impervious Surface Area: Part of the Waterways and Drainage charge on your bill covers management of stormwater runoff - which contributes to flooding and water quality issues in our waterways and bays. Urban Development (e.g. houses, buildings, roads and carparks) generates run-off from hard surfaces during storm and rainfall. We refer to these hard surfaces as impervious surface area. Property owners currently pay a flat charge which reflects the principle of shared benefit for services provided in the greater Melbourne region. Residential houses in Melbourne pay on average $100 per year. Businesses are moving towards a flat charge of approximately $150 per year. An alternative is to design the charge so that those with more impervious surface area pay more for their impact. Most residential properties are similar in size and have a similar amount of impervious surface area. Some businesses have larger impervious surface areas. The flat and ‘user pays’ approach are alternative ways of collecting the same amount of revenue. There are two option to consider
Option One: Retain current arrangements (everyone pays a fixed flat charge) An example of another fixed fee charge you may pay includes your car registration Benefits
Most customers would pay a similar amount
under either a flat charge or impervious surface area
charge
Predictable and steady bills for customers
Low administration costs for Melbourne
Water to administer
Disbenefits
Those who contribute more to the problem
do not pay more for their impact on stormwater
runoff.
Those who are contributing to the problem
may not be aware of actions they can undertake to
mitigate their impact.
Option Two: Investigate moving to a user pays (everyone pays by their impact) Examples of other ‘impact’ pays charges you may pay includes charges for additional rubbish bins provided by councils or when you pay to dispose of waste at your local tip. Benefits
Those contribute more to the problem pay
more for their impact on stormwater runoff
May encourage customers to reduce their
impact by doing works on their properties to reduce
stormwater runoff
Disbenefits For the majority of customers, the bill wouldn’t
change significantly. This would not provide enough
of a price signal to encourage action to reduce
impervious surface area.
Impervious surface area information would
need to be collected and maintained for every
property in Melbourne. This is costly, resource and
time consuming and does not pick up water tanks
and other infrastructure that property owners may
have already installed to reduce their runoff.
Pricing is more complex to develop,
implement and maintain.
(Q9) Over the next five years from 2021, what approach for charging businesses for waterways and
drainage services do you support?
Melbourne Water | Pricing Submission 2021 Community Research | February 2020 page 80
C.1.a I support Melbourne Water to continue with
current flat charging model for impervious surface area
C.1.b I support Melbourne Water to investigate
moving to a ‘paying for your impact’ charging model for
impervious surface area

SECTION B: EDUCATING MELBURNIANS
ASK ALL
Western Treatment Plant Access and Ecotourism The Western Treatment Plant (WTP) is an internationally significant site for migratory birds and is an important part of protecting the health of Port Phillip Bay. We want to ensure that the biodiversity and habitat at WTP is protected and valued and able to be enjoyed by everyone in Melbourne. Additional investment in education materials, programs and resources would benefit school groups, members of the community visiting the plant and the broader population. Ecotourism can help educate the community about this world-renowned site of environmental significance by facilitating visits for people who wouldn't otherwise be able to experience it. Investing in boardwalks would make the site more accessible, and huts for birdwatching would increase visitor capacity, improve their experience and minimise disruption to bird life We already provide some access to bird watchers but we could provide additional paths, boardwalks and bird hides so that people can safely access the key areas of the site and ensure that the biodiversity and habitat values are protected.
(Q10) In five years from 2021 which option for investment in ecotourism do you support?
B.1.a Melbourne Water to maintain current level
of ecotourism facilities at the Western Treatment
Plant
B.1.b Melbourne Water to invest in additional
ecotourism and visitor facilities at the Western
Treatment Plant to facilitate visits for people who
wouldn’t otherwise be able to experience it.
Paths, boardwalks and bird watching hides will make
the site more accessible, protect habitat and minimise
Melbourne Water | Pricing Submission 2021 Community Research | February 2020 page 81
disturbance to birds, increase visitor capacity and
improve visitor experiences.
An interpretive heritage walk will provide
opportunities for visitors to understand the site’s
history.
This will encourage additional visitors to the WTP and
learn about the site’s heritage (natural and built), the
water cycle and biodiversity.
Cost $0.47 per year paid by sewerage customers as

Water Cycle Education and Awareness Currently, what happens to the water that has been used in homes and business is not well understood by the community. Increased knowledge in the community about water as a precious resource allows people to make smarter water choices and minimise their impact on the environment. It also helps them have their say in discussions with Melbourne Water and others on how Melbourne’s water needs should be met in future. Working alongside the retail water companies, Melbourne Water currently runs education programs, but these could be expanded. For example, digital education programs for the whole community could be offered. Melbourne Water could partner with organisations such as universities and Museums Victoria to leverage funding and extend the reach of these programs. More facilities for visitors to the Western Treatment Plant and Eastern Treatment Plant could also be offered, including immersive experiences to educate visitors about the water cycle and innovative technologies that could be used in future.

SECTION C: SIMALTO EXPERIMENT We’ve talked a lot about the different things Melbourne water could do to balance affordability with preparing for future challenges like climate change and population growth – ensuring Melbourne remains healthy, green and prosperous for generations to come. We’d now like you to consider the options we’ve talked about, and select the ones you would like to see Melbourne water implement. Making these changes will cost money, and part of those costs will be passed on to consumers like yourself. These prices will be reflected in your bill from 2021, and will be a once-off increase to pay for all the actions you would like to see Melbourne Water invest in. You can use the table below to select different options that you believe Melbourne Water should choose, on behalf of Melburnians. As you select options, the box below will update to reflect the bill increase the average customer would expect to see. The average water bill is $1,000 per year and the increase per year is shown as a dollar amount. While making selections, please keep an eye on this amount – we want you to only select options that you’re willing and prepared to pay for. If you feel the number increases too much, you can change some of your selections.
