1. Introduction

1.1 Introduction Council is a registered Water Service Provider (WSP) under the Water Supply (Safety and Reliability) Act 2008 (the Act) and one of its legislative obligations is to provide an annual performance report on prescribed indicators nominated by the Department of Natural Resources, Mines and Energy (DNRME), (previously the Department of Energy and Water Supply (DEWS)) in its role as the Queensland Water Supply Regulator (the Regulator). The data required by the Regulator covers details such as connected populations, asset information, water treatment and sewerage treatment volumes, staff information, system performance, customer service and financials. The water and sewerage data required by the Regulator was loaded into the Statewide Water Information Management (SWIM) portal to meet the 7 October 2019, lodgement date. In addition to the lodgement of data into the SWIM system, Council must also publicly publish its performance with commentary on key indicators.

This report satisfies Council's requirements under Section 142A of the Water Supply (Safety and Reliability) Act 2008 ("the act"), to prepare a performance report on water and sewerage services for the 2018-2019 financial year.

The report is structured to give an overview of the extent of Council's water and sewerage schemes followed by discussion on results of some of the key performance indicators (KPI's) for water services and sewerage services lodged in the SWIM system. The data lodged in the SWIM system is included in Appendix A.

This report also includes an overview of the Cassowary Coast Regional Council's adopted Customer Service Standards and the performance against these standards.

A major component of this report documents the performance of Council's drinking water service with respect to water quality and performance in implementing the actions detailed in the drinking water quality management plan (DWQMP) as required under the Water Supply (Safety and Reliability) Act 2008..

The report assists the Regulator to determine whether the approved DWQMP and any approval conditions have been complied with and provides a mechanism for providers to report publicly on their performance in managing drinking water quality.

2. Background of Cassowary Coast Regional Council's Water and Sewerage Operations

2.1 What we do Cassowary Coast Regional Council is the water service provider responsible for delivering drinking water to a connected population over 24,852 water customers in a region between Cardwell and Innisfail and sewerage services to a connected population of 15500 in the towns of Tully, Mission Beach and Innisfail.

Since August 2018 Cassowary Coast Regional Council has also been responsible for the operation and maintenance of the Port Hinchinbrook sewerage system, located south of Cardwell on behalf of the Queensland Government.

To support these services Council undertakes the following functions:

2.1.1 Provision of water distribution, sewage transportation and treatment including: • Demand forecasting and management • Asset planning • Asset management • Operational and maintenance activities associated with the running of 6 water supply intakes,

1 water treatment plant, 9 water supply chlorination stations, 30 water reservoirs, 14 water pump stations, 814 km of water mains, 2 sewage treatment plants, 58 sewerage pumping stations, 229km of gravity sewerage and 64 km of sewer rising mains (excludes Port Hinchinbrook assets).

• Capital works to replace aging assets or upgrades to suit system growth • Trade waste management

2.1.2 Customer interface and service provision relating to: • Water meter management and data • Residential billing and customer management • Infrastructure search requests • Development assessment • Trade waste oversight

2.1.3 Enabling functions for business sustainability including: 1. Strategy development 2. Financial and people management 3. Community and stakeholder engagement 4. Regulatory and legislative compliance 5. Information, communication and technology 6. Procurement and contract management

6

2.2 Our Operating Environment - Water Supply Cassowary Coast Regional Council is regulated to ensure that safe drinking water is provided to the community through a number of Acts of legislation including:

• Water Supply (Safety and Reliability) Act • Water Act • Public Health Act • Local Government Act • Environmental Protection Act

The Department of Natural Resources, Mines and Energy (DNRME) is responsible for managing water supply allocations that are available from the creek and river systems that Council uses as source water for its water supply system.

DNRME (through the Regulator) is responsible for managing compliance with Water Supply (Safety and Reliability) Act to ensure water service providers such as CCRC provide a water supply to consumers that meets Australian Drinking Water Guidelines and is safe for consumers to drink.

Queensland Health also have responsibilities under the Public Health Act to ensure water supplies are safe for the community. The interaction and distinctions in regulatory authority between DNRME and Queensland Health is particularly evident for CCRC when boil water events are declared as the notifications of water quality incidents is provided to DNRME but approval to lift a boil water alert is issued by Queensland Health.

CCRC water supply services are managed in accordance with the CCRC Drinking Water Quality Management Plan (DWQMP) to ensure water supply to customers meets Australian Drinking Water Guidelines.

Key features of the DWQMP include descriptions of each treatment and distribution scheme; raw water quality parameters, water testing history, risk assessments, improvement plans, sampling procedural manuals and critical control procedures. The DWQMP must be able to satisfy the requirements of section 95 of the Water Supply (Safety and Reliability) Act 2008. The objective of the DWQMP is to establish a risk based management system that the Service Provider follows to ensure the provision of drinking water to a high quality that protects public health.

Council's DWQMP was initially approved by DEWS in October 2013. In May 2017, Council received DNRME formal approval of a revised DWQMP.

2.3 Our Operating Environment - Sewerage Services The key regulatory framework for Council's sewerage services is provided by:

• Water Supply (Safety and Reliability) Act • Public Health Act • Local Government Act • Environmental Protection Act

Council's environmental sewage treatment facilities (Innisfail and Tully) are licenced under the Environmental Protection Act (EPA). The regulatory authority for activities licenced under the EPA is the Department of Environment and Science (DES). Key conditions of Council's licences relate to discharge limits, testing requirements to ensure process control, receiving waters monitoring, reporting requirements and approved discharge and overflow locations.

7

Pollution events such as exceedances of discharge limits or dry weather spills must be reported to DES within prescribed time frames. Noncompliance with licence conditions can result in infringement notices with fines or more serious legal action.

2.4 Key Achievements in 2018-19 Our key achievements for 2018-19 included the following:

Water

• Supplied 6,086 million litres of drinking water to an estimated connected population of 24,852 • In both Innisfail and Tully, Council continued with the water main asset renewal program. The

renewal program has been focusing on the replacement of the 1930’s and 1940’s unlined cast iron water mains which suffer from extensive internal ferric corrosion and the replacement of aging asbestos cement mains with a history of failures.

• Replaced and upgraded approximately 6km of aging cast iron (CI) water mains and asbestos cement (AC) mains in the Innisfail and Tully water scheme regions.

• Completed the construction of new inline filters and new chlorine dosing facilities at Nyleta Hill reservoir site.

• Completed the deployment of smart metering to the Kurramine Beach, Silkwood and El Arish areas. • Operated the new bore facility at Cardwell to supplement supply during turbidity events in Meunga

Ck. This project was awarded best public works engineering project under $1 million in Queensland for 2018-19 by the Institute of Public Works Engineering Queensland (IPWEAQ)

• Completed the program of deployment of SCADA to all key water infrastructure including all reservoirs, pump stations, flow meters and control valves.

• Completed construction of an extension of the existing Innisfail Water Office. • Commenced construction of the 4.6 ML Wheatleys Hill reservoir and associated civil works. • Formalised the application process for a lease from the Tully Gorge National Park for the proposed

Bulgun Creek intake reservoir. A contract has been awarded for the supply of the prefabricated glass coated steel reservoir. Tenders were called for the civil works and erection of the intake reservoir.

• Awarded a contract for the supply and erection of a lightweight aluminium domed roof for the Stoters Hill reservoir in Innisfail to replace a degraded vinyl floating roof.

• Water Asset Management Plan adopted by Council.

Sewerage

• Treated4,228 ML of sewage at the Innisfail and Tully Sewage Treatment Plants (STP). • Constructed two flow meter pits at sewage pump stations SPS8 and SPS12 to enable better

monitoring of flows into the network. • Relined 6.0 km of sewer reticulation network in Innisfail and Tully. • Implemented a magnesium hydroxide dosing system to the Mission Beach system that controls the

release of hydrogen sulphide mitigating odour issues and slowing the impact of corrosion on the 22km DICL rising main from Mission Beach to the Tully STP as well as the impact of corrosion to pump station assets.

• Initiated a magnesium hydroxide dosing trial in the Innisfail sewerage network. • Completed construction of a new control building at the Tully STP • Awarded a design and construct contract for the construction of the new inlet works and grit

chamber at the Tully STP. • Sewerage Asset Management Plan adopted by Council. • Review of the requirement for a second secondary clarifier at the Tully STP.

2.5 Water Supply and Sewerage Services - Background Cassowary Coast Regional Council operates and maintains four water supply schemes and three sewerage schemes, providing safe drinking water and sanitation services to the majority of the region. Currently Council is also responsible for maintaining and operating the Port Hinchinbrook sewage system on behalf of the Queensland State Development Agency.

2.5.1 Water Supply Scheme Overview The four (4) water supply schemes include:

• Innisfail • Nyleta • Tully • Cardwell

The Innisfail Scheme is the largest water supply scheme and is the only scheme with a designated tertiary water treatment plant. Water is extracted from the Johnstone River and is treated at the Innisfail Water Treatment Plant before being distributed through a water reticulation network. The water treatment plant (WTP) has a maximum capacity of 18.2 ML/day. Treated water is pumped from the WTP to the Stoters Hill reservoir before gravity feeding to the customers via a series of reservoirs and pump stations. The Innisfail reticulation network includes Innisfail, Daradgee, Wangan, Flying Fish Point, Mourilyan, Mourilyan Harbour, South Johnstone, and Mena Creek. The Innisfail Scheme has a water storage capacity of 27.1 ML spread across ten (10) reservoirs.

The Nyleta, Tully and Cardwell schemes are supplied by run of creek offtakes. These offtakes gravity feed into the reticulation network. The Nyleta Scheme is also supplemented by a bore located at Jurs Creek.

The Nyleta intake is located on Nyleta Creek (a tributary of Liverpool Creek) and has a maximum daily allocation limit of 3.6 ML/day. Water is filtered, disinfected and then distributed through a water reticulation network. The Nyleta Scheme supplies the communities of Silkwood, El Arish, Kurrimine Beach, Bingil Bay, and Mission Beach. Reservoirs are located near key communities and provide both daily but also emergency storage in the advent of a pipeline failure or boil water event. There are seven storages capable of storing 9.5 ML throughout the network. The Jurs Ck bore is the other existing water source for the Nyleta Scheme. The bore delivers approximately 0.7 ML/day to the Fenby's Gap reservoirs, which supply part of Mission Beach.

The South Liverpool Ck sub bed filtered intake has a maximum daily water allocation of 10ML/day. Combined with the allocation of Nyleta Ck , there is ample “theoretical” allocation available for long term population projections for the Nyleta scheme.

The South Liverpool intake and adjoining 3.3 ML Nyleta Hill reservoir are key initiatives to improve water quality in the Nyleta scheme area. Automation and SCADA of turbidity sensing, control valves and pumps allow the intake on Nyleta Ck to be closed during periods of high turbidity in the creek following heavy rain. During extended periods of turbidity in Nyleta Ck, the pumps connected to the new subbed filtered intake on South Liverpool Ck can be started and used to recharge the reservoir. Typically for smaller periods of turbidity spikes in Nyleta Ck, the clear water storage in the reservoir is ample but, during sustained periods of elevated turbidity it is also necessary to utilise the new sub-bed intake to top up the reservoir. CCRC has observed that the new sub-bed intake can draw water from the filters in South Liverpool Ck at below 5NTU (turbidity units) even though South Liverpool Ck is flowing with very high turbidity (levels of 40NTU). One of the other functions of the sub bed intake is that it can draw sub bed creek flows in periods of dry weather when Nyleta Ck flows cannot meet demand. As the South Liverpool Ck intake system is pumped, Council utilises the gravity Nyleta Ck intake as much as

10

possible and currently runs the South Liverpool system only when Nyleta Ck is very low, or impacted by turbidity.

Fifty micron in-line filters at Nyleta reservoir remove any of the larger material that passes the 200 micron inlet screens before the water discharges into the reservoir.

The Tully Scheme is supplied by separate intakes at Boulder Creek and Bulgun Creek, which have daily maximum allocation limits of 4.55 ML/d and 6.4 ML/d respectively. The annual allocation available to Council at Bulgun Ck is 1200ML and Boulder Ck is 1564ML. These intakes service the Tully, Mission Beach, Tully Heads, Hull Heads and rural areas surrounding Tully and Mission Beach. Overall there is a total storage combination of 4.2 ML within the Tully Scheme. Major increases in available water storage have been planned for the Tully scheme to better manage long term demand and to assist with clean water supply during periods of turbidity in either Bulgun Ck or Boulder Ck. Construction is well advanced with a new 4.6 ML reservoir at Wheatleys Hill to supplement the existing 0.7ML storage. This new reservoir will supply the communities of Wongaling, South Mission Beach, East Feluga and Carmoo and is due to be completed in November 2019. Council is also moving forward with the construction of a new 4.5ML reservoir near the Bulgun Ck intake. A lease is being negotiated to allow construction of the reservoir within the Tully Gorge National Park. Contracts are in place for the supply of the reservoir (glass coated steel) and the earthworks and erection. It is anticipated civil works will commence in December 2019 and it is anticipated the new Bulgun intake reservoir should be completed by May 2020. A system of turbidity analysers will be installed at both the Boulder Ck and Bulgun Ck intakes. When the flow at either or both sources becomes turbid and above 5NTU, a system of valves at the intakes will automatically close and water will be supplied from the clean water storage in the reservoirs. The inlet valving will reopen automatically when the turbidity drops below 5NTU. This system of controlling has now been well proven at both Nyleta intakes and at Cardwell.

The Cardwell Scheme is supplied from an intake located on Meunga Creek and has a daily maximum allocation limit of 5.6 ML/d. Water is gravity fed to the Cardwell reservoirs for storage and distribution. A pump station and reservoir at Stony Creek supplies the southern part of Cardwell. Total storage capacity in the Cardwell network is 2.8 ML. A bore on Ellerbeck Rd near the Kennedy School also supplies water to the Cardwell Scheme. During periods of high turbidity in Meunga Ck, the intake can be isolated and the Cardwell community can be supplied by clear water storage in the reservoirs supplemented by the bore. The closure of intake valves and the start-up of the bore is a fully automated system. Major rainfall events that trigger high turbidity in Meunga Ck are mitigated, by switching supply to the bore. Using the bore, Council has avoided a number of potential boil water alerts. This project was selected by the Institute of Public Works Engineering Queensland as the best public works project under $1 million in Queensland.

2.5.2 Sewerage Schemes Overview The three (3) sewerage schemes include:

• Innisfail • Mission Beach • Tully

Sewage treatment plants (STP) are located at Innisfail and Tully. The Innisfail Sewage Treatment Plant has capacity of 40 ML/day (Peak Wet Weather Flow). The Tully Sewage Treatment Plant has a capacity of 12.5 ML/day (Peak Wet Weather Flow).

The Innisfail sewerage network is restricted to the Innisfail residential footprint and the Belvedere subdivision. Thirty-one (31) pump stations collect and transfer sewage to the Innisfail STP. Treated effluent from the Innisfail STP is discharged to Ninds Creek.

The sewerage network in Mission Beach collects sewerage from Mission Beach, Wongaling Beach and South Mission Beach and pumps it to the Tully STP via the Mission Beach Main Transfer Station and 22 km of 300mm diameter sewer rising main.

The Tully sewerage network collects sewage from the residential and industrial areas surrounding Tully prior to pumping to the Tully STP. Treated effluent from the Tully STP is discharged to Banyan Creek.

Figure 4: Aerial image of the Innisfail STP

CCRC are also currently operating and maintaining the Port Hinchinbrook sewerage scheme on behalf of the Queensland Government State Development Agency. This is being operated by staff from the Tully treatment team. The Port Hinchinbrook system consists of 10 sewage pump stations and a treatment plant. The pumping and treatment infrastructure at Port Hinchinbrook was in a poor condition when Council commenced the operation of this facility. With the funding assistance of the

14

State Government, Council has undertaken a number of minor improvements to ensure the system operates more effectively.

2.6 Our People Cassowary Coast Regional Council Water total workforce is 54 FTE (full time employees). The workforce is spread over a range of disciplines including treatment, reticulation, trade waste, maintenance, supervision and management.

The Council operates three (3) water depots with the majority of the workforce based in Innisfail. The gender profile of our workforce is majority male. A significant portion of the workforce is 50 years or older. Council recognises this is an issue and is actively engaging in an apprentice employment and skills training program. Council currently employs 5 apprentices spread across two disciplines; plumbing a mechanical trades.

Council staff from the Innisfail, Tully and Cardwell areas are being utilised to maintain and operate the Port Hinchinbrook sewer network and treatment facility. This puts an additional demand on staff and resources as there has been no increase in staffing to maintain and operate this deteriorated asset.

16

2.7 Our Catchments Rainfall across the Cassowary Coast catchments for 2018-19 was in line with the long term averages for Innisfail and Tully and above average for Cardwell, mainly as a result of rain received in December 2018 and January 2019. Rainfall was below average for the first 5 months of the financial year to end of November 2018. Rainfall in December and January was well above average with in excess of 1,500mm received in Innisfail and Tully and 1,200mm in Cardwell. The months February to June received below average rainfall in Innisfail and Tully. Tully received the most rainfall with 3,8627mm. Cardwell was again the driest area with 3,031 mm of rain for 2018-19..

17

Total streamflows of 2,200 GL were recorded in the North Johnstone River during 2018/19, with 409 GL recorded in January 2019. All other intakes are upstream of the gauging stations, therefore it is difficult to get an accurate representation of the streamflow past the intake.

Our Emissions Overall Council produced 5410 t of CO2 in the provision of water and sewage services to the community. This is equivalent to 1,149 passenger vehicles driven for one year1.

Of the 5410 tonnes produced, over 3900 tonnes were produced through the consumption of electricity for the collection and treatment of sewage.

Council has commenced a significant program in the deployment of solar power systems around its facilities to offset costs of energy and reduce CO2 emissions. As part of this program, major solar facilities will be erected at the Innisfail STP and the Innisfail WTP in 2020. A small scale 26KW solar power system has been erected as part of the new Tully STP control building.

3.1.3 Capital Works Projects 2018-2019 Water Pipeline Upgrades During 2018-19 Council continued with its renewal programme of water mains. The value of water main renewal works undertaken was approximately $3.2M. Typically the existing 100mm mains in the CBD areas of Tully and Innisfail are being upgraded to 150mm diameter to allow for long term growth and to improve fire-fighting provision. Water main renewals in 2018-19 were:

• Innisfail o Rankin Street CI WM Renewal (Emily to Alice – 150mm Diameter) o Alice St CI WM Renewal (Owen to Fitzgerald – 150mm Diameter) o Fitzgerald Esp CI WM Renewal – (Alice to Grace St WM-150mm Diameter) o Glady Street CI WM Renewal (Lily Street - Edith Street – 150mm Diameter) o Bruce Hwy CI WM Renewal (Blackwood to Pine-100mm Diameter) o Owen Street CI WM Renewal (Grace Street to Alice Street- 150mm Diameter)

• Tully o Andersen St – (Bruce Highway - Tully Depot- 200mm Diameter) o Wheatleys Hill Reservoir – (Inlet and Outlet Pipework- 300 and 375mm Diameter) o Brosnan Street Tully CI Main Renewal (150mm Dia). Works were also commenced on

Trower St, King St and a section of Murray St. • Nyleta

o Wilson Street El Arish AC Main Replacement- (100mm Diameter) o King Road to Daveson Road -Replace the class 10 GRP- (300mm Diameter) o Porters Promenade (Seaview St to Council caravan park -200mm Diameter and 90mm

Diameter service mains) To replace failing AC and improve system capacity to commercial area of Mission Beach.

• Cardwell o Balliol St AC Mains Replace (100mm diameter) o St Albans St New Water Main (100mm Diameter). Improve firefighting and system

redundancy to commercial strip. o Brasenose St New Water Main (100mm Diameter) To improve firefighting and system

redundancy to commercial strip. o Bowen Street AC Mains Replacement – (Part of a running program – 150mm Diameter)

The replacement of old 1930’s and 1940’s unlined cast iron water mains will continue to be the major focus of the programme in Innisfail and Tully. The replacement of asbestos cement mains in all regions is based on age, service priority and particularly failure history. In rural areas, small scale renewals are also being undertaken of AC mains with failure history by inserting a smaller polyethylene main inside the original 100m host pipe. Typically the polyethylene insertion main is either a 63mm or 80mm outside diameter. This is significantly less expensive than new construction. Fire hydrants cannot be provided on these mains so there is some reduction in fire-fighting standard of service where Council is undertaking this form of renewal.

20

Wheatleys Hill Reservoir During the 2018-19 financial year, Council began the construction of the Wheatley’s Hill reservoir. This reservoir when finished will have a capacity of 4.6 ML and serve the zone east of the Bruce Highway which includes east Feluga, Carmoo, South Mission and Wongaling Beach. It is anticipated that this reservoir will be completed in November 2019.

The construction of Wheatley’s Hill Reservoir is a part of Council's Sustainable Water Quality Plan and is an integral part of its plan to reduce turbidity in the water supplied to the Mission Beach area during major rain events. The reservoir will also provide Council with the storage capacity required for predicted population growth and to deal with maintenance issues.

Smart Metering During 2018-19 Council continued the replacement of meter and services in the Kurramine Beach, El Arish, Silkwood and Tully areas.

The consumption data from the smart metering is nearly real time and is now being used by Council to identify and notify residents of water leaks. Council also uses the data for billing purposes.

Council now has approximately 3500 smart metering devices deployed and Council has committed to continue the installation of smart metering across all parts of the region.

SCADA SCADA technology continues to be deployed to water infrastructure across the region. SCADA allows Council to remotely monitor conditions and operating parameters of its treatment systems, pumps, reservoirs, bulk water meters, disinfection systems and key control valves. The technology allows changes to systems to be undertaken remotely and data is also able to be collected and analysed on all components. For example, during turbidity events Council receives alerts when the intake sources are becoming turbid. Disinfection systems are automatically adjusted to increase disinfection dosing rates and the SCADA allows critical valves at the intakes to be automatically closed to isolate the intakes and supply from our clear water storages.

Planning and Design Activities In November 2018, Council endorsed the planning report Tully Water Supply Scheme – Review 2018 This report on the Tully Water Supply Scheme identified deficiencies in the network storage capacity and outlined reservoir storage proposals to meet current and future population growth and deficiencies in the number of barriers employed to provide treatment to the water source.

An integrated system of water storage reservoirs in the network has been proposed to reduce the risk of loss of supply to the entire network allowing each reservoir to serve a defined geographical zone and population. As full treatment of either the Bulgun and Boulder Intakes systems is unlikely in the foreseeable future (due to cost constraints), the focus of the planning report is the provision of a robust system of storages and inlet controls that allow the inlet systems to be isolated when turbid and rely on the clear water reservoir storages. To achieve this goal, three new reservoirs would be required, Bulgun Ck intake reservoir (operational May 2020), Hyatt St high level reservoir (due 2026) and the Wheatleys Hill reservoir (operational November 2019), along with modifications to the operation of the existing network. This report also flagged the need for a detailed investigation of options to improve water security for the Tully Scheme. Further water security planning will commence in 2020.

In the Cardwell scheme, considerable planning has been undertaken to identify a suitable site for an intake reservoir. Applications have been lodged with the relevant statutory bodies to secure a lease

21

area from the National Park near the Meunga Ck intake. It is envisaged the outcome of these negotiations will be resolved by mid 2020. The construction of the Cardwell intake reservoir is currently programmed for commencement in 2021/22.

The pending introduction of Health Based Targets (HBT) by the Water Regulator in Queensland Water Supplies will also drive further improvements to the all water supply systems. Council worked with the regulator in having an audit undertaken by Viridis Consultants of the Nyleta supply scheme to gain an appreciation of the likely works that may be required to meet HBT for the Nyleta Ck and Liverpook Ck sources and the Jurs Ck bore supply systems. It is anticipated some of the recommendations are transferrable to Council’s other supply schemes. Major improvements that have been identified as being necessary with the creek systems include the installation of UV disinfection systems to supplement the existing chlorination systems. The range of issues identified by Viridis need to be transferred to Councils DWQMP Improvement Plan. The 10 year budget plan does include substantial future funds for UV systems in all supply schemes.

During 2018/19, Water Section worked with the Manager Asset Engineering to develop asset management plans for water and sewerage. The Water AMP identified a shortfall of renewals expenditure of $53.3M over 10 years (based on current renewals budgets). Future renewal budgets will need to increase to better balance this shortfall but planning work also needs to be done to optimise the renewals program. It is recognised that much of the rural network is not economically viable in that the income stream from water charges does not offset depreciation and operational costs for the asset. Further work needs to be done to rationalise these uneconomical assets. This may include options to downsize mains or to decommission mains. It will take considerably more investigation to develop policy documents to support the decommissioning of mains. Where mains are requiring urgent renewal and downsizing is practical, Water Section is using polyethylene pipe pulled through the existing host pipe to achieve a more economical renewal.

3.1.4 Our Customers There has been a slight increase in the equivalent population receiving water supply services over 2017-18 equivalent population levels. It is estimated that Cassowary Coast Regional Council supplies over 24,852 people with safe drinking water distributed as shown below.

3.1.5 Our Supplies Of the 5,743 ML supplied during 2018-19, 37% was used for residential purposes, 18% was used by commercial purposes (including businesses such as backpacker accommodation, sugar mills, hotels/motels, laundries and cafes) and 45% was unbilled (other factors) . Water referred as "other" is non-revenue water and includes losses from leaks/mains bursts and metered water used for mains flushing and auto-scours, and water from overflowing reservoirs.

Figure 2 Break down of drinking water supplied to customers

The breakdown of non-revenue water for each scheme is shown in the Table below. The largest component of non-revenue water is “unaccounted for”, being losses from a combination of leaks, faulty meters, illegal connections, illegal standpipe use, or overflowing reservoirs.

Scheme Innisfail Tully Nyleta Cardwell

% of Non-Revenue Water per Scheme

48.1% 43.8% 43.2% 31.6%

The scale of “unaccounted water” is unacceptable. A strategic planning document is being prepared to outline the strategies, program and costs to reduce the unaccounted for water to reasonable levels. Some strategies to address this issue are well underway including the replacement of the aging meter fleet, smart metering, and some in system trunk metering. These works will continue over the next few years but other matters will also be addressed in the strategy including increased levels of pressure zone management additional network flow monitoring and leak detection surveys.

The volume of water supplied per residential connection utilises metered consumption data and highlights the residential consumption trends in each of the supply areas. Cardwell Scheme residents consume the most water with an average of 221.8kL per connection (608 L /day), although this has reduced from 271.8kL per connection in 2017-18. Nyleta Scheme residents consume the least at an average of 209.3kL per connection (573 L/day).

Figure 3 Annual residential water supplied to customers per scheme

3.1.6 Our Demand The maximum daily demand for the 2018/2019 year was 9.6 ML in Innisfail, 7.4 ML in Tully, 1.9 ML in Cardwell and 3.1 ML in Nyleta. Maximum daily demand increased in Tully and reduced in Innisfail, Nyleta and Tully when compared to 2017/18.

Figure 4 Maximum daily demand per scheme

The maximum daily demands as indicated above represent: • 53% of the maximum Innisfail WTP capacity; • 68% of the Tully maximum daily allocation limit from Boulder Creek and Bulgun Creek; • 34% of the Cardwell (Meunga Creek) maximum daily allocation limit; and • 22% of the combined Nyleta Creek, South Liverpool Creek maximum daily allocation limit plus the

capacity of the Jurs Creek bore.

The available spare maximum daily allocation for the Tully Schemes is a long term issue that needs further investigation. To some extent, the spare capacity in the Nyleta scheme can supplement the overall Mission Beach regional demand by drawing water from Nyleta into the Tully Scheme through

24

the 250mm diameter inter-connection of the Tully and Nyleta scheme near Mission Circle off Tully-Mission Beach Rd.

A larger issue across the region is the lack of water security during periods of sustained drought. The flow in all of Council’s creek and river supplies are highly susceptible to sustained dry weather. Water restrictions are required in all schemes in the months prior to the commencement of the monsoonal system. It is not uncommon for level 3 restrictions to be required. Water security planning will be a major strategic focus in 2020/21. Initiatives undertaken to date include:

• Council applied to DNRM to obtain an increase to the allocation limits for the creek systems of the Tully Scheme. Total annual allocations for both creeks combined has been increased from 1764ML to 2764ML. No increases have been provided for maximum day demand which remain at 10.95ML/day combined for both creeks.

• The maximum daily allocation limit granted by DNRME for South Liverpool Creek is 10ML/day. This new allocation significantly improves the water security for both the Nyleta and Tully Schemes. The inter-connection of the Nyleta and Tully Schemes includes a new 250mm diameter water main along Tully-Mission Beach Rd, between Mission Circle and Stephens St and was completed in 2015-16. This allows flow to be directed from the Nyleta Scheme (including South Liverpool Creek) into the Tully Scheme and vice versa.

• Demand management is another issue that Council is currently undertaking. The introduction of smart metering has commenced with the roll out complete in Mission Beach, Kurrimine Beach, El Arish and Silkwood. It is currently ongoing in the Tully region. .

• System leakage is being addressed through the installation of District Meters (DM). Leak detection programs are being implemented particularly in the Innisfail and Tully schemes.

3.1.7 Asset Performance - Water Length of Mains Of the 814 km of water mains in the Cassowary Coast Regional Council area, the Tully Scheme has the highest representation followed closely by the Innisfail Scheme. The Cardwell Scheme has the smallest length of water main.

25

Network Density Proportionally the density of population supported by the water reticulation network is quite sparse. As can be seen from the water reticulation network maps, all schemes have extensive networks servicing rural areas with very low levels of population. By contrast, most other large water authorities in Queensland have network densities of over 100 people per km of water main.

Water Main Breaks Water main breaks per 100 km of water main are an indication of how reliable a water service is. Main breaks burst due to a variety of reasons. The biggest cause of main breaks within Cassowary Coast is the material type of the water mains, operating pressures, the soils they are laid in and the height of the groundwater table.

26

Class 12 white pvc had been used quite extensively in region between 1990 and 2000. System pressures in the southern region can exceed 100m without pressure regulation and it is believed that many of the failures of the "white" pvc pipe result from accelerated fatigue of the pipe material due to high pressures. Pressure regulating valves are now installed in most high pressure zones but most of the damage is believed to have accumulated prior to the installation of the pressure regulation.

Other problems that are causing problems with the network are the standard of bedding and backfill that was used in many installations. During repair activities, it is commonly noted that the existing pipes were not bedded in sand and hence are susceptible to damage and failure from external abrasion damage or point loadings.

High water tables have also been observed to be impacting the condition of asbestos cement pipes. The ground water in much of the region is very soft and continued exposure weakens the cement matrix of the pipes. This softening of the pipe combined with high pressures has been observed to be a cause for a number of failures of asbestos cement pipes.

The Tully Scheme had the highest number of breaks per 100 km of water mains followed by Nyleta. Both of these schemes have a large amount of pipeline installed in rural areas where there is greater evidence of poor installation practices and where the pipes were operating for many years under high pressures. In the Tully Scheme, of the 300 km of pipe, approximately 50% is class 12 pvc and approximately 20% is asbestos cement. The former pipe material has issues with fatigue failures and the latter has issues with softening due to high ground water levels.

There were 89 mains breaks in the Tully Scheme area (29.84 breaks per 100km of pipe) and our records show that 50% of all breaks occurred on rural mains with low numbers of serviced properties and with very poor rates of return. There did appear to be a surge in breaks in Tully last year compared to other years. This could in part be attributed to the especially dry season last year and the impact such dry conditions have on soil movements.

In the Nyleta Scheme with 15.85 breaks per 100km of pipe, 7 of the recorded 21 breaks occurred on rural mains with low numbers of serviced properties and with very poor rates of return.

Water Losses Real water loss is the difference between the water supplied and water accounted for. Water lost includes leakage from mains and burst mains, water used in fire fighting, illegal use of non Council standpipes and errors with water meters (reading low). Water used in flushing programs is not included as "lost water" as it is accounted for with metered standpipes. In terms of losses, the Innisfail Scheme is subject to the highest water loss per km of water main. Cardwell has the lowest real water losses per km of water main.

The volumes of unaccounted water are a significant concern and substantial effort and funding will be directed to improving this outcome.

The loss in the Innisfail Scheme is a particular concern as all reticulated water in this scheme is fully treated and pumped on multiple occasions.

Strategies for improvements in demand management and reduction in system losses are funded in the 10 year plan including:

• Introduction of a main leakage detection program • Continued deployment of smart metering and more in system metering to be able to locate

leaks in the system faster; • Accelerated replacement of aging meter fleet; • Replacement of commercial meters with combined fire/domestic uses; • Pressure management of high pressure zones; • Increased funding for replacement program of aging or problem mains • SCADA communications and data management systems which enable real time monitoring of

flow rates and pressures in the network.

A strategic planning document is being prepared that outlines a number of capital and operational programs that need to be implemented over the coming years to provide significant and permanent reductions in the proportion of unaccounted for water.

3.1.8 Financial Performance - Water Operating Costs Operating costs for water have reduced slightly in comparison to 2017-18 with decreases in Cardwell and Innisfail. Depreciation costs have increased since 2017-18 with further increases likely in 2019-20 as major capital items such as Wheatleys Hill and Bulgun reservoirs are capitalised. The operating costs figures below are inclusive of operational and maintenance expenses, rates, insurance and internal charges for IT and other section support to the Water Section.

Capital Works Excluding carryover funds, new capital funding in 2018-19 increased from $6.1M to $9.6M. Significant elements in the 2018-19 capital funding program included:

• Funding of $3.11M for replacement of aging mains in each of the schemes • Funding of $0.4M for upgrade to Tully Showgrounds water main • Funding of $2.1M for construction of the new reservoir at Wheatley’s Hill • Funding of $2.0M for construction of the new reservoir at Bulgun Creek • Funding of $0.87M for SMART meter rollout. • Funding of $0.16M for Water Meter & Service renewal • Funding of $0.54M for installation of network water meters to allow improved monitoring of

water consumption and losses in the network

Written Down Asset Replacement Cost Taking into account depreciation to date, the estimated written down value (WDV) of all assets on a scheme basis is summarised below:

Water Scheme

Overall Cardwell Innisfail Nyleta Tully

WDV 2018-19 $142.7M $17.8M $52.8M $30.0M $42.1M

WDV 2017-18 $136.2M $16.4M $50.8M $28.7M $40.3M

Revenue (All Sources) Revenue for each of the schemes is outlined below:

29

Water Scheme

Overall Cardwell Innisfail Nyleta Tully

Revenue 2018-19 $10.57M $0.95M $4.74M $1.66M $3.22M

Revenue 2017-18 $10.59M $0.97M $4.64M $1.72M $3.25M

Total revenue is steady compared to 2017-18 with an increase in Innisfail of 2.2% offsetting decreased revenue in all other schemes. The largest decrease in revenue was 3.5% in Nyleta. Tully and Cardwell were steady compared to 2017-18. Average residential consumption has decreased in all scheme areas which is impacting revenue. This has been partly offset by the increase in charges.

Financial Sustainability The overall financial performance of each water supply scheme is represented by the calculation of the economic rate of return (ERR) for each scheme as summarised below:

Water Scheme

Overall Cardwell Water

Innisfail Water

Nyleta Water Tully Water

ERR 2018-19 1.04 0.93 1.12 0.10 1.67

ERR 2017-18 1.06 0.85 0.86 0.33 1.91

Note: Where ERR = Revenue from water business operations less operating expenses (operation, maintenance and administration expenses (OMA) + current cost depreciation) for the water business divided by written down replacement cost (WDRC) of operational assets for the water business.

The rate of return has decreased slightly across all schemes, with increases in Cardwell and Innisfail offsetting decreases in Nyleta and Tully. The Innisfail scheme has benefited from an increase in revenue in addition to reduced depreciation expense. Nyleta has been impacted with increased depreciation expenditure and reduced revenue partially offset by reduced operational expenditure. Tully also had increased depreciation and operational expenditure, with revenue remaining steady compared to the previous year. The rate of return of Tully will continue to reduce once the new reservoirs at Wheatleys Hill and Bulgun Ck intake are completed. Council has a sound strategy to incrementally increase water charges for all schemes but particularly the southern schemes once water quality infrastructure measures are implemented that eliminate boil water events. This is necessary given the forecast for declining rates of return.

Council should also give consideration to the options to improve the rate of return from parts of the rural networks. In many instances Council is paying substantial depreciation and maintenance costs for water main assets with few connected properties. Records are being gathered of uneconomical service areas and it is anticipated this issue will be elevated to Council for further consideration in 2020. Options could include higher charges regimes in some areas, changes to renewal strategies (insertion of polyethylene mains inside the host pipe) or possibly changing the water serviced area (no provision of water to some customers in uneconomic areas). For this latter option, some compensation would be payable to allow the consumers to install alternative supply systems such as rainwater tanks. Potentially this compensation could be $10,000 to $15,000 per connection. Budgets would need to be developed for this strategy.

30

Funding for Water Assets In June 2019, Council adopted the Water Asset Management Plan (AMP) which outlined the funding requirements of the next ten years to meet the pending renewal of water assets that are reaching their theoretical asset life. The age profile of water assets is shown below. Aside from the Innisfail treatment plant and network reservoirs, the major cost elements of these asset values are water mains.

The majority of water mains before mid 1950’s were predominantly cast iron (CI). Many of these CI assets were unlined (without a cement lining). The CI mains in Innisfail were predominantly installed in the 1930’s. The CI mains in Tully were mainly installed in the 1940’s. Unlined CI suffers from extensive internal ferric corrosion which causes pitting to the iron and the ferric nodules can seriously impact the flow capacity of the pipe. Council has adopted a useful life of 80 years for it’s cast iron water mains so much of the CI network has already exceeded the theoretical useful life and these assets are no longer being depreciated. A renewal program is underway in Innisfail and Tully to replace these unlined CI mains.

From the mid 1950’s to the early 1980’s the predominant pipe material was asbestos cement. The life expectancy of asbestos cement is highly variable and is dependent on the water table depth, water alkalinity and pH, pressure conditions and installation practices. Council has adopted an asset life for AC pipes of 60 years so the large sections of the AC network installed in the 1950’s and 60’s are now nearing the end of their useful life. A portion of the current water mains renewal budget is being allocated to replace aging AC mains but particularly the mains with a history of failures.

The majority of pipes installed in the 1990’s were class 12 “white” pvc. Unfortunately this type of pipe has shown to be particularly susceptible to fatigue failure from pressure pulses and these sections of pipe must be carefully pressure regulated otherwise they fail well before the end of their useful life. The white pvc Mission beach trunk supply main on Tully Mission Beach Rd was replaced in 2013 because of repeated occurrences of this failure mechanism. White pvc has been given a recommended useful life of 50 years which should see the majority of these assets renewed in about 30 years.

31

Since about the year 2000, Council has been using either ductile iron cement lined pipes or class 16 modified PVC (Mpvc). These assets have a recommended useful life of 80 years.

The AMP contains an overview of renewal funding going forward until 2039. Refer graph below. The renewal funding requirements in the next 20 years are largely related to water main renewals as these assets reach the end of their nominal useful life. Separate work on water main renewals has identified that theoretically Council has a water mains renewal funding requirement of $77 million between 2019 and 2032. This would require a smoothed renewal funding commitment of a minimum of $5.5 million per year. In 2019/20 Council committed $2.95M for water main renewals and in 2020/21, it is anticipated Council will commit about $2.8million. This relatively low level of funding is being constrained by the need to fund major capital works such as the reservoirs at Wheatleys Hill, Bulgun Intake, Cardwell Intake and Hyatt St over the next 5 years.

The ongoing and growing requirement for water mains renewal funding will be a challenge for budgets going forward and Council will need to be innovative with renewal technology and construction methods to minimise the renewal expense. Council will also need to increase its focus on measures such as pressure management to increase the working life of its assets.

3.1.9 Customer Service Performance - Water General Council has a customer request (CR) system where customers notify Council of specific issues such as faulty meters, leaking water services, leaking water mains, water quality issues (turbidity or taste), lack of pressure, lack of flow and other miscellaneous matters. Upon notification of the issue, Council staff respond to the issue and either rectify the problem immediately or in other cases, program for planned work. Details of all responses to customer requests are compiled by the responding officer within Council's Technology One Data base system.

32

A summary of complaints gathered in all scheme areas is provided in Appendix B. The type of complaints and numbers of complainants is summarised below.

Water quality complaints Water Scheme


Number of water quality complaints 11 22 3 13

Quality complaints per 1000 connections

9.9 3.6 1.4 3.5

Many of the water quality complaints in Innisfail relate to dirty water following mains breaks, dislodgement of materials from cast iron pipes or lack of flushing from end of mains.

Many of the water quality complaints in Tully mainly relate to turbidity spikes following rainfall events, a lack of flushing of mains or dirty water following mains breaks. Although the Tully system has a number of turbidity related dirty water incidents in the year, the numbers of water quality complaints indicates people are not complaining about these issues.

Water service complaints Water Scheme Cardwell Innisfail Nyleta Tully Number of water service complaints 3 40 28 69

Water service complaints per 1000 connections

2.7 6.5 12.7 18.8

The Tully Scheme is more highly represented in this data. A number of factors are involved:

• The system pressures in the Tully Scheme are typically higher than other schemes resulting in more leakage at service connections.

• There is more problem pipe material (class 12 pvc) in the Tully Scheme than other schemes. • The average age of meters in the Tully Scheme is higher than other schemes.

The meter replacement programme and associated renewal work on service connections being undertaken in the Tully township as well as the role out of the smart metering program should eventually see a reduction in water service complaints.

There is still an issue with the time recording of staff when they attend to water incidents. An investigation of the response time statistics indicate the averages are being skewed by outliers where the CR has not been closed out until some time (the next day) after the action was completed.

4.1.3 Capital Works Projects 2018-19 Sewer Relining Program During 2018-19 Council continued its substantial investment in the relining of its old gravity sewers in Innisfail and Tully. The older sewers have major issues with displaced joints and other failures that allow ground water infiltration into our systems. This infiltration of ground water has a major cost implication as all infiltration is pumped with sewage to the treatment plants and then passes through the full treatment systems. Any reduction in infiltration that can be achieved through relining works has tangible cost benefits in pumping and treatment costs. The relining process involves forming a new pvc sewer pipe inside the original pipe. The as-new pipe is structurally rigid and involves minimal disturbance to properties.

SPS 06 The previous SPS 06 pump station in Jodrell St, Innisfail was a fibreglass pump well. Settlement of soft strata under the pump well has caused the well to settle unevenly and rotate causing the fibreglass walls of the well to crack. The damage was irreparable

A new 1.8 m diameter well was located immediately adjacent to the existing pump well. The scope of works for the SPS6 replacement included a new switchboard in a purpose built structure above flood level.

36

Tully Sewage Treatment Plant Control Building Work commenced on a new control building at the Tully Sewage Treatment Plant. The building will replace the existing control building that is not suitable to occupy any more. Initial earthworks were finalised in March 2019 with construction commencing in April 2019.

The new control building consists of two laboratories, a data room, kitchenette and control room and will meet the needs of the water and sewage treatment team in Tully. The existing control building will be removed from site.

Tully Sewage Treatment Plant Inlet Works In June 2019 the contract for the design and construction of a new inlet works and grit chamber was awarded. The new inlet works will replace the existing inlet works and provide a greater level of redundancy to the treatment plant. The grit chamber will capture grit that is carried in the sewage and improve the treatment efficiency of the plant.

The inlet works will be completed in March 2020.

37

Figure 5 Representation of the new inlet works at the Tully STP

Planning and Design Activities During 2018/19, Water Section worked with the Manager Asset Engineering to develop asset management plans for water and sewerage. The Sewerage AMP identified that budgets are keeping pace with renewal requirements. In part this is due to the effectiveness of the sewer relining strategy which has been a very cost efficient method to re-life our gravity sewer systems.

A review of the requirement for a second secondary clarifier was also undertaken for the Tully STP. This review focused on what would be the key drivers for the construction of a second secondary clarifier. The outcome of this review identified that based on current flows and the projected population growth rate that the existing clarifier has a biological capacity until at least 2036. However duplication of the existing clarifier would facilitate extended maintenance periods during the dry reducing the operational risk of only having a single clarifier.

Initial planning for the upgrade to the Tully STP Motor and Control Centre also began in this financial year. This planning involved an assessment of whether the current MCC can be modified to house a larger switchboard. The outcome of this assessment determined that it was not feasible to modify the existing building and instead a new building with new switchboards would be more cost effective.

38

4.1.4 Our customers The majority of customers are serviced by the Innisfail sewerage scheme followed by Mission Beach and Tully. Overall Cassowary Coast Regional Council supplies 15,000 customers with sewerage services.

Residential properties make up the majority of the customers with 90% of the overall properties serviced. Commercial properties are significantly smaller representing 10% of the properties serviced.

4.1.5 Our treatment Cassowary Coast Regional Council treats 100% of the sewage received at the Sewage Treatment Plants (STP) to a tertiary level. All sewage treated is discharged to either Ninds Creek in Innisfail or Banyan Creek in Tully.

The Innisfail STP treats significantly more sewage than the Tully STP. Not only is this due to the higher population but Innisfail also suffers greater problems with ground water infiltration into its network.

39

For the year 2018-19 Innisfail STP treated over 3,232 ML of sewage, while Tully STP treated 997 ML of sewage. In total 4,228 ML was treated for the financial year.

There is still a direct correlation between extreme rainfall and the treated flows of the treatment plants. Very high rainfall in the Tully and Innisfail systems causes significant surface water infiltration through overflow relief gullies and manholes. Ground water infiltration is gradually being improved through the relining programs in Tully and Innisfail. Ground water infiltration from private house drainage lines will continue to be an ongoing issue. At some point in the future, Council may have to dedicate special operational funding to repairing failing private sewers where the owners are not taking action to repair known faults.

During 2018/19, the maximum inflow into the Innisfail STP was 24.95ML on the 16 December 2018. The minimum flow for the year was 2.08ML on the 10 November 2018. This represents a peaking of 12. At the Tully STP, the peak flow was 14.4ML on the 2 April 2019. The minimum flow was 1.1ML on 10 October 2018. This represents a wet weather peaking of up to 13.06. Considering Mission Beach does not have significant wet weather infiltration, the bulk of the Tully STP wet weather flows were originating from the Tully town reticulation.

For the period 9 November 2018 to 4 February 2019, the wet weather bypass of the oxidation ditch at the Innisfail STP was out of action due to a component failure. This may have contributed slightly to the above increase in flows through the Innisfail STP during 2018/19 but the more likely fact was probably the longer extent of wet weather in 2018/19.

Wet weather overflows have also now been completed for all the major Tully sewage pump stations so this should also reduce the treated volumes passing through the Tully STP during significant wet weather events.

The majority of sewage is residential and non trade waste. Trade waste, including septic, makes up a small portion of sewage but is higher strength than residential sewage. This requires higher operational monitoring to ensure that CCRC doesn’t breach its environmental licence conditions.

40

The Innisfail STP treated 388 kL per person in the 2018-19 financial year compared to the Tully STP of 149 kL per person. Groundwater infiltration is a significant factor in the treatment flows per person for the Innisfail Scheme. The Tully Scheme also suffers from significant infiltration but the overall average at the Tully STP is reduced as there is minimal ground water infiltration from the Mission Beach Scheme, which is connected to the Tully STP.

4.1.6 Asset Performance - Sewerage Length of Mains Of the 229 km of sewerage main throughout the Cassowary Coast Regional Council, 105.8 km is in Innisfail, 89 km is in Mission Beach and 34.2 km is in Tully2.

Note: These figures combine the lengths of rising mains and gravity sewer mains. Variances between Mission Beach and Tully reflect changes where assets were incorrectly posted in the asset register.

Mains Breaks or Chokes Sewer main breaks/chokes are caused by a number of things including poor maintenance, disposable wipes, fat and grease build up, age of the sewer pipe and tree root penetration to name a few. Tully has the highest number of chokes per 100 km of sewer main followed by Innisfail and Mission Beach. It is possible the reduction in chokes could be reflective of the extent of relining works completed in the Innisfail and Tully schemes. As part of the relining works, the sewers are cleaned and roots are removed.

Biosolids The current biosolids removal contractor for the Tully and Innisfail STP's is Arkwood. Approximately 2,000 tonnes of biosolids were exported from the both the Innisfail and Tully STPs in 2018-19. Depending on weather conditions, biosolids are used on agricultural properties for beneficial improvement of the soil.

4.1.7 Financial Performance - Sewerage Operating Costs Operating costs for sewerage reduced slightly from $8.36M in 2017-18 to $8.23M in 2018-19.. Overall, there is a decrease in expenditure for the Sewerage Program of $0.13M. This is mainly as a result of increase in operating costs and a reduction in depreciation. Operating costs are inclusive of operational and maintenance expenses, rates, insurance and internal charges for IT and other section support to Water Section.

Capital Works Excluding carryover funds, new capital funding in 2018-19 was $3.3M. Significant elements in the 2018-19 capital funding program included:

$849K for relining of gravity sewers in Innisfail, Tully and Mission Beach; $250K for renewal of section of rising mains or sewers that cannot be repaired by relining; $240K for SCADA; $630K for Sewer Pump Stations;

$1,060K for upgrade to Tully STP.

Written Down Value of Assets Taking into account depreciation to date, the estimated written down value (WDV) of all assets on a scheme basis is summarised below:

Financial Sustainability The overall financial performance of each sewerage scheme is represented by the calculation of the economic rate of return for each scheme as summarised below:

Sewerage Scheme

Overall Innisfail Mission Beach

Tully

ERR 2018-19 1.45 2.06 -0.01 3.07

ERR 2017-18 1.20 1.66 0.10 2.27

Note: Where ERR= Revenue from water business operations less operating expenses (operation, maintenance and administration expenses (OMA) + current cost depreciation) for the sewerage business divided by written down replacement cost (WDRC) of operational assets for the sewerage business.

In simple terms, the ERR is a percentage return on the written down replacement costs of the assets. A zero ERR is break even.

These calculations show that the revenue stream from sewerage charges is just sufficient to ensure a positive rate of return on the value of the assets.

Overall, the ERR for Cassowary Coast has increased from 2016-17 due to an increase in revenue which offsets the operating expenditure increase. A reduction in depreciation expenditure has also contributed to the improved result. Mission Beach continues to be impacted by high depreciation expense.

Each of these treatment plants and the reticulation system at Mission Beach has capacity for populations well in excess of current connections and the depreciation and borrowings costs of these facilities is currently being borne by a comparatively small population. (It should be noted that interest payments are excluded in the ERR calculation.)

Strategies (with associated capital funding) have been developed, which will have some moderate impact on the operational cost of the sewerage schemes. Relevant strategies include the relining program to reduce ground water infiltration and the improvement of overflow facilities at key pump stations. These works will reduce pumping costs and treatment costs which will have some modest impact on operational expenses for electricity and chemical consumption.

A review of benchmark data of the sewerage charges of other authorities indicates that CCRC sewerage charges are some of the highest in the State. Sewerage charges are unlikely to fall in the near future without significant increases in the population base.

45

Funding for Sewerage Assets In June 2019, Council adopted the Sewerage Asset Management Plan (AMP) which outlined the funding requirements of the next ten years to meet the pending renewal of sewerage assets that are reaching their theoretical asset life. The age profile of sewerage assets is shown below.

The major cost components in the 1970’s relate to the installation of the reticulation network in Innisfail and Tully. The treatment plants originally constructed at that time have since been replaced and are reflected by costs in 2007/8 and 2015.

The major cost component in 2004 to 2006 relates to the sewerage work for Mission Beach.

The gravity sewer lines installed in the 1970’s through to the 1980’s were either vitreous clay (VC) or asbestos cement (AC). Due to failing joints and extensive ground water infiltration Council has invested significant funds to reline these gravity sewer assets, even though the assets had not reached the end of their useful lives. It is envisaged all VC and AC gravity sewers will be relined by about 2022. The relining uses a structural pvc lining so the asset life can be reset for another 80 years. A revaluation of water and sewerage assets is to be undertaken in the 19/20 year and one of the issues it will need to address is the appropriate methodology and costs for depreciation of the relined sewers.

The anticipated accumulated renewal budget for the next 10 years is $19.2 (or smoothed, $1.9million per year). Council is currently committing sufficient funds to meet this renewal cost requirement. The graph below shows the forecast funding requirements until 2039.

47

4.1.8 Customer Service Performance - Sewerage General Council has a customer request (CR) system where customers notify Council of specific issues such as odours, blockages, sewerage overflows. Upon notification of the issue, Council staff respond to the issue and either rectify the problem immediately or in other cases, programme for planned work. Details of all responses to customer requests are compiled by the responding officer on a water activity form and details are input into Council's Technology One Data base system.

Sewerage staff based in Tully are responsible for responding to all incidents in the Tully and Mission Beach Schemes in addition to their normal daily functions associated with maintenance of the sewerage network. Response times for all areas are commendable. The Mission Beach response time is not included as one of the incidents was a low priority and action was not undertaken to resolve the matter until some 6 days after notification. Hence for this reason the average response time for Mission Beach s deemed invalid.

5. OUR CUSTOMER SERVICE STANDARDS

5.1 Delivering against our Customer Service Standards Council has endorsed a Customer Service Charter that outlines Council's agreed obligations for water and sewerage services to its customers. The Customer Charter documents customer service standards, the process for service connections, billing, metering, accounting, customer consultation, complaints and dispute resolution. The Charter also includes obligations of customers when they agree to take our services.

Commentary on the performance against the target CSS is included in the notes below and the discussion above.

The Customer Service Standards require some revisions to reflect changes to the key performance indicator reporting requirements of the Regulator. Also response time indicators need to better reflect the agreed outcomes from the Customer First project. Revisions to the Customer Service standards require formal advertising and the requesting of submissions on the proposed changes before they can be adopted. This work will need to be done in 2020.

Notes:

1. As in previous years, the Tully Scheme suffers the largest numbers of mains breaks. The Tully area has high operating pressures, significant class 12 pvc and evidence of historically poor installation practices.

2. This indicator is calculated by dividing the total number of mains breaks/leaks per 1000 connections. This is no longer a KPI of the Regulator.

3. Average response times for mains breaks has improved and is typically significantly less than 5 hours. As mains breaks are treated as a priority, the response times are short. Data for response times on water service issues (often a much lower priority if no loss of water) is still being corrupted by poor data entry. A phone call by a Supervisor to a customer is the first response but this is not always captured and if the Supervisor ascertains the issue is minor or there are other more urgent priorities, the field work could be delayed. This would impact the data recorded on the logging sheet.

4. Restoration of service times has seen a good improvement in all areas.

5. The volume of water lost per connection per day is outside the target range for the Innisfail (490L/Conn/day), and Tully Schemes (518L/Conn/day

6. Numbers of water quality complaints were within targets for all regions. Highest complaints were in Cardwell with 9.9 complaints/1000 conn. Tully, recorded 3.5 quality complaints per 1000 connections. Considering the issues with turbidity after rain events impacting the Tully scheme, the numbers of quality complaints is very low.

7. For 2018-19 E.coli was detected in 5 samples. Refer DWQMP Report Water Quality Incidents. Detections were linked to extreme turbidity in the source waters following extreme rainfall. A boil water notice was in place on each instance that the E.coli was detected.

8. Numbers of sewerage chokes or breaks were well within targets.

9. Response times to sewerage incidents were generally well within targets with the exception of 1 non critical incident at Mission Beach which has skewed the overall result.

6. DWQMP Report - Review of Compliance with our DWQMP

6.1 DWQMP REPORT Pursuant to sections 141 and 142 of the Water Supply (Safety and Reliability), a DWQMP Report must be prepared for each financial year and must be given to the Regulator within 120 days after the end of the financial year to which it relates. The report assists the Regulator to determine whether the approved DWQMP and any approval conditions have been complied with and provides a mechanism for providers to report publicly on their performance in managing drinking water quality.

6.1.1 Background

One of the major water quality challenges facing Council is the management of turbidity with its run of the creek systems following periods of heavy rainfall. Each of the run of the creek intakes for the Nyleta, Tully and Cardwell Schemes are susceptible to these turbidity events. The DWQMP Improvement Plan includes a number of strategies to better manage the impact of turbidity. A copy of the DWQMP Improvement Plan with comments on the status of the improvements is included in Appendix D:

Key initiatives that are in the process of being implemented to better manage turbidity are outlined below:

Nyleta Scheme: Construction of a new 3.3ML reservoir and a new sub bed filtered intake on South Liverpool Ck were completed in late 2017. The reservoir has sufficient storage for a minimum of 24 hours without any inflow. This new intake will filter turbid source water and allow water to be drawn from South Liverpool Ck and pumped to the new reservoir. Works have proven highly effective at avoiding the need to implement boil water notices to the Nyleta Scheme.

Tully Scheme: Planning and design commenced for a new intake reservoir near the Bulgun Ck intake. This will allow the intake sources (Bulgun Ck and Boulder Ck) to be isolated during periods of turbidity. Contracts for the supply and construction of the new intake reservoir have been awarded. Construction is scheduled to commence in January 2020. This project has been delayed due to the lengthy process to secure a lease for the reservoir site in the Tully Gorge National Park.

Council has almost completed construction of additional network storage at the Wheatleys Hill site. Valving and procedures have been implemented to isolate the South Mission Beach area during periods of turbidity with this area relying on reservoir storage and supply from the Jurs Ck bore.

Cardwell Scheme: During periods of turbidity in Meunga Ck, the intake is isolated and the Cardwell region supplied by existing storage capacity in the reservoir supplemented with flow from the new bore. Works have proven highly effective at avoiding the need to implement boil water notices to the Cardwell Scheme. Planning has continued for a reservoir at the Cardwell intake and negotiations are well advanced to secure a lease from the National Park.

Concerns about chlorine dosing levels have been expressed by Queensland Health and DEWS, particularly in relation to these dirty water incidents when Council increases dosing levels to maintain disinfection. Whilst Council has no immediate plans to test for disinfection by-products, the turbidity control measures that Council is actively implementing will be a positive measure to improve the risks associated with liquid chlorine disinfection by-products.

39

HBT Assessment for Nyleta Scheme In early 2019, Viridis Consultants were engaged by DNRME to undertake a health based target assessment of the Nyleta Drinking Water Supply Scheme. Viridis completed their investigations in June 2109 and their final report entitled Nyleta Health - Based Targets Assessment Detailed Report was completed and provided to Council in August 2019. Key findings are:

• The source water from Nyleta Ck was categorised in the assessment as Category 2. No catchment improvements were identified. The source water from Liverpool Ck was identified as Category 4 and the report made recommendations to allow the source waters to be classified as Category 2. These works include temporary closure to the South Liverpool Ck swimming hole during times of extraction and improvements to the septic facility at an upstream scout hut. These matters have been presented to Council but as yet no works have been undertaken. Council continues to monitor both creeks for ecoli and large detections are not being observed.

• To meet HBT log reduction value requirements for Category 2 source water, ultra-violet light disinfection systems need to be implemented in addition to the systems for turbidity management and chlorination,. Funding has been allowed in the nominal 10 year budgets for these works.

• In relation to the Jurs Ck bore, the source water was identified as Category 1. Some process improvements were recommended including conductivity monitoring and on-line turbidity instruments. These recommendations have not as yet been implemented.

Viridis supplied an improvement plan as part of the report. This is attached in Appendix E. Further consideration is required on some of these recommended improvements before formally endorsing in Council’s DWQMP.

6.1.2 Water Quality Test Data During 2018-19, Council undertook an extensive amount of water quality testing on the raw water supply and in the network. The sampling and testing program was in accordance with the DWQMP Appendix E - Sampling Manual. The summary of the testing program results for 2018-19 are included in Appendix C. Comments are provided in the tabulated data for any exceedances of water quality parameters. The testing data in Appendix C demonstrates a high level of water quality is being maintained in all schemes notwithstanding that high rainfall events do trigger elevated turbidity in the reticulation networks of the run of the creek systems. Increased levels of water quality testing are initiated as part of the DWQMP Quality Control Plan procedures when a boil water alert is triggered. Boil water alerts are triggered when critical alert levels are reached for water quality parameters as outlined in the DWQMP Quality Control Plan. Turbidity levels above 5NTU for more than 4 hours is the primary factor resulting in the boil water alerts mainly issued for the Tully scheme. No boil water alerts were initiated for the Innisfail and Nyleta schemes. Cardwell only had one boil water alert due to alternative supply (Kennedy bore) generator failing and having to switch back over to the Cardwell Intake.

At this stage, Council is not testing for Cryptosporidium. The testing for this parasite is a high cost and complex and currently beyond the resources of Council. There is some risk that Cryptosporidium may exist in any of the untreated water supplies (Nyleta, Tully and Cardwell) but the risk is probably low given that the harmful form of Cryptosporidium is less likely to be present in the pristine upstream forested / wet tropics catchments.

38

6.1.3 Water Quality Incidents The table below summarises all incidents that were reported to the Water Regulator during the 2018-19 year. There were 11 incidents that resulted in the issue of a Boil Water Alert. Most of the boil water alerts impacted Tully. Cardwell had one boil water alert on January 2019. Measures are being implemented as part of the DWQMP Improvement Plan to eliminate the need for boil water alerts arising from turbidity spikes.

A discussion was held with SGS Laboratories on 12 October 2018 requesting that in future when there is an exceedance of trigger limits, the treatment plant operator needs to be notified immediately so action can be taken. A further response from SGS on October 17 stated that their IT section will be able to put something in place to give an immediate response when test results are outside of trigger limits.

After the incident on the 16 January 2019 a temporary cable was reconnected between the old switchboard and the new board to give indication of any faults. The connection was not completed by the afternoon of the 17th so the plant effluent was diverted to the storage lagoon overnight in case the fault were to happen again. The effluent from the lagoon was then be pumped back to the head of the plant over the following days. The alarm system was reconnected and tested on the 18th.

On the 13 December 2018 an overflow incident was recorded from SPS9 into the Johnstone River. This incident was due to a fault with the alarming system. No alarms were triggered after the pumps blocked from ragging. This appears to have been a random electrical equipment failure that could not have been predicted.

SPS 3 Rising Main Failures

The only other advices to DES through the pollution hotline system relate to failures of the 450mm diameter ductile iron cement lined sewer rising main from pump station 3 to pump station 1 in Innisfail. The pipe has been damaged by long term abrasion in the pipe invert. Five failures have occurred from November 2017. All failures have occurred during or immediately following periods of heavy rainfall when the pipeline is under increased pressure and the pumps are operating more frequently.

After the initial failure on 21 November 2017, Council was unclear on the extent of the abrasion damage so planning, design and construction was initiated to construct a bypass arrangement (near the upstream section of the main) with valving to divert the rising main into a gravity sewer in the pump station 1 catchment. This section of gravity sewerage is 450mm diameter and has a significant spare capacity. The diversion was completed on 13 December 2018. It was intended the bypass would allow Council to camera the line and determine the extent of the abrasive scour. Coincidently the next failure of the rising main in Martin St occurred on 13 December and we were able to use the bypass to relieve the system. Since that date, the bypass has been used to divert flow during the repair activity of subsequent failures in Wrights Park (3 to date) and has been a major factor in minimising the volume of each spill. Council has observed from the pipe failures and the condition of the pipe at the bypass cut-in that the abrasion scour is extensive and the full length of the pipe needs replacement or relining. Damage to the pipeline at the upstream end near the bypass point was not as extreme as the downstream sections in Wrights Park.

44

As of 17 July 2019, Council has converted to the bypass system on a full time basis until such time as the repair works are completed. The pumps at pump station 3 are set at 30Hz which can pump 155L/s. The pumps at pump station 1 have been ramped up to a minimum of 46Hz and will now pump 240-280L/s.

The pump flow rate for pump station 3 in bypass mode (155L/s at 30Hz) is approximately 8 times dry weather flow (8*18.6 L/s) and it is proposed that for inflows in excess of this coming into the pump station that the pump station goes into overflow. Such wet weather overflows will discharge to the river as per normal wet weather events. It is Council’s view that such wet weather overflows are still permitted under the terms of the Environmental Authority for the sewerage system. As the proposed renewal of the rising main will be undertaken during the dry season, it is unlikely there will be prolonged periods of high flows into pump station 3 and the likelihood of overflows is low.

Note: The flow rate for WWTP is the combined flow from MP01 and MP03 which is equivalent to the flow rate of the bypassed system that we have now set in place.

Since the conversion to the bypass, Council has been progressing planning, design and construction of a renewal of the SPS3 rising main. The renewal of rising main will utilise a new 450mm outside diameter polyethylene pipe by a combination of normal open trench construction (Council work-force) and by inserting/dragging the polyethylene pipe through the existing 450mm ductile iron pipeline (Contract works). The scope of the open trench works and the pipe dragging sections are shown on the attached plan.

The works to replace the sections of the rising main along the Corso and in Wrights Park are well advanced and are due for completion in mid-December.2019. The contract for the polyethylene insertion pipe has been awarded. It is expected works will be commencing on the section upstream of the bypass by early December 2019. The Contract works have been delayed and are unlikely to be completed before commencement of the wet season and the associated larger flow rates. If wet weather flow exceed the capacity of the bypass system it may be necessary to force a wet weather overflow from SPS3. This is still in accordance with DES licence provisions.

8. Conclusions

8.1 Conclusions 8.1.1 Water Operations

• This performance report outlines the data collected for the Statewide Water Information Management (SWIM) and provides commentary against many of the performance indicators in the SWIM data and Council’s adopted Standards of Service. Information is also presented that demonstrates Council’s activities comply with its approved Drinking Water Quality Management Plan.

• Performance against Standards of Service indicators suggests good outcomes in relation to response times and restoration of service times for water mains breaks/ loss of service. High levels of compliance are being achieved for water quality parameters. Total water mains breaks per 100km of main is much higher than the nominated indicator and reflects historically poor laying practices, deteriorated assets and high working pressures. Substantial improvement is needed to reduce water losses to the nominated Standard of Service indicator.

• Some of the performance indicators in Council’s current Standards of Service need to be amended to reflect changes to the reporting requirements in the SWIM data. This should be undertaken in 2020 along with minor changes to the Customer Charter to align the response times implemented in the Customer First project.

• Council is meeting its regulatory obligations as a water service provider.

• The network for each region is extensive and the network density (population served per km of main) is low compared to most other large water authorities. The rate of return of many rural mains is poor. Income from water charges in some rural areas does not adequately cover operational costs and depreciation. Further investigation is needed across all schemes to identify uneconomic mains and develop options to improve their rate of return. Options could include inserting a smaller polyethylene main through the existing mains when these mains reach the end of their serviceable life (this entails accepting a lower standard of fire-fighting standard of service); decommissioning some mains or creating a different charge system to better recover costs.

• Mains breakages are more common in the Tully and Nyleta Schemes, which have extensive rural distribution systems. Breakages can be correlated to poor installation practices, large schemes with high pressures and usage of class 12 pvc pipe.

• The asset management plan for water assets has identified a substantial increase is needed to fund the renewal program of cast iron and AC mains. Existing funding of approximately $2.9 million for renewals will need to increase to about $5.5million. This increase will be constrained by other significant capital requirements for reservoirs in the Tully and Cardwell. In Innisfail and Tully the water mains renewal program is focusing on the replacement of cast iron mains at the end of their asset life and which are suffering from internal ferric corrosion. Mains replacements are being prioritised based on the connection type, fire flow demand and function of the main.

• Water losses are high in all schemes. Water loss is the difference between the water volume that leaves the treatment plant / intake and the summation of all metered volumes from all consumers, metered standpipes and metered auto-scourers. Unmetered water is typically from main breakages, leaks, faulty property service meters and water theft. The water loss in Innisfail is a particular concern as the lost water is fully treated and pumped. A planning document for Water Loss Management is currently being prepared with a program of capital

39

and operational projects. Strategies being recommended include increased flow monitoring, field leak detection, and the creation of more pressure regulated zones. Funding for the recommended capital components of the Loss Management Strategy will be phased in over 4 years.

• The financial position of the water operations is fair and improving with the increase to water charges, particularly in the southern schemes. Council has undertaken substantive works to improve water quality for all its run of the creek water supply schemes. The elimination of the majority of boil water events due to the construction of turbidity monitoring, control systems and reservoir storages will assist the case for an increase in water charges to the southern regions.

• Staffing levels servicing the Tully Scheme need to be increased to improve the response times in that scheme, particularly in light of the poor condition of many of the assets.

• The new 4.6 ML Wheatleys Hill reservoir at South Mission Beach is due to be completed in November 2019.

• Contracts have been awarded for the supply and erection of a glass coated steel reservoir for the Bulgun Creek intake. Construction has been delayed pending resolution of a lease for the reservoir in the Tully Gorge National Park. Construction of the intake reservoir is scheduled to be completed in May 2020.

• Planning is continuing for an intake reservoir near Meunga Creek intake and applications have been lodged for a lease form the National Park for the reservoir.

• SCADA deployment is complete for all major water supply infrastructure and is having a significant effect on water quality control measures.

• Viridis Consultants undertook a health based target assessment of the Nyleta supply scheme (Nyleta Creek, South Liverpool Creek and the Jurs Creek bore) on behalf of DNRME. This assessment was formally completed in August 2019. A number of recommendations are included in the report which require actions by Council. A HBT improvement plan has been provided.

8.1.2 Sewerage Operations • Performance against Customer Service Standards indicate good outcomes with low numbers

of sewer breakages/blockages, generally acceptable response times to sewerage incidents and low numbers of odour complaints. The level of sewerage infiltration particularly for Innisfail and Tully town is still higher than desirable.

• Aging reticulation networks in Tully and Innisfail suffer extensive infiltration problems. Significant capital funding is being directed to sewer relining programs, which should in part address the infiltration problem. Peak wet weather flows into the treatment plants are still high (probably due to the influence of surface infiltration) but after the heavy rains cease, the sewage flows are reducing at a faster rate than previous suggesting the relining is having an impact on ground water infiltration.

• Response times to sewerage incidents in the Tully and Mission Beach Schemes are impacted by fewer operational staff in that area.

• Significant capital expenditure has been committed to upgrade facilities at the Tully Sewerage Treatment Plant. A new control building has been completed and new inlet works incorporating two screens and a grit chamber are under construction.

• The financial position of sewerage operations is fair to poor. Measures are in place to streamline some operational expenses but significant factors such as depreciation for the treatment plants (compounded by the small population base), will constrain any efforts to reduce sewerage charges. Rising electricity costs will also put strain on operational budgets.

40

The introduction of major solar facilities at the treatment plants should offset some of the cost increases from the network power supplier.

• DES have been advised of two breaches of licence conditions relating to treatment operations at the Tully Sewerage Treatment Plant and 4 breaches in relation to dry weather spills from the reticulation network. The major non-compliance issue relates to the continuing failures of the SPS3 rising main. Council has given DES undertakings to replace this asset as a matter of priority. Works are underway to replace the failing DICL main. It is hoped all replacement works will be completed by end of January 2020.

Council tests came back clean.

1 Number customer complaint was received from within the Innisfail Scheme on 15 November 2018 related to Customer reports that feet are 'sticky' after hosing under the house with water only, customer also reports that the water smells of chlorine. Customer advised that she moved into this house two weeks ago. Water tests were conducted and were well within ADWG E-Coli also collected. The chlorine smell was coming from the bathroom sink but no smell was present today. The smell is probably from it being the first tap turned on for the day and line just needs a quick flush. The stickiness seems to be from the size sticker on her thongs or residue from the brand new cheap hose. E-Coli sample from yesterday is all clear. 0 - coliforms, 0 - E-Coli. WT2018/1750.

1 Number customer complaint was received from within the Innisfail Scheme on 28 November 2018 related to Customer has phoned and has reported that the water at the mill is very dirty and staff are refusing to drink it.

WT2019/0095. **** from CCRC spoke with the Customer this morning with regards to the metallic taste and discolouration of her tiles and sink, the metallic taste has all but gone now that we are supplying water from the main intake once again, I said it is too late now to test the water but next time we switch over to the bore we will test in the area to try and pin point anything that may be out of the ordinary , The Customer was ok with that and said she just wanted to bring it to our attention and thanked council for returning her call.

1 Number customer complaint was received from within the Innisfail Scheme on 01 February 2019 related to Customer has found the water coming through the taps is cloudy and has an appearance of foam on top of the water whilst the tap is on. As noted to you my wife has concerns re the water and we are now currently boiling our water. Having said that my wife is still reluctant to drink the water even after it has been boiled. She is concerned the water is unsuitable to drink and is worried she may fall ill if she drinks the water straight from the tap. She believes it is a health issue that needs to be investigated. We can understand there may have been unclean water at the start but can’t understand why the water hasn’t come clear after a few days. We have not tasted the water from the tap because of the appearance of the water and the seemingly foamy residue that sits on the top. Can we ask you please to have the water checked to see what the water contains and inform us of same. WT2019/0184. CCRC Staff Scoured water main to remove air from system on 04/02/19 & 16/02/19.
