Basis of Submission
Inadequately maintained, unable to
meet peak demand, and requiring significant
investment

Water – A Key National Resource
• Drinking Water:– Essential “Food” Product– On Tap 24/7– Meet New Development Needs
• Water:– Industrial Processes– Raw Material– Fire Fighting Resource
• Waste Water Services:– Public Health– Environmental Protection– Storm Water Drainage

EFFICIENT INFRASTRUCTURE
![Page 10: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/10.jpg)
Efficient Infrastructure – Where are we now?
• Major Victorian Age Water/Wastewater Services remain critical to our towns and cities
• Investment for last 50 years had 2 main priorities
- Meeting capacity for new development - Meeting new EU standards of treatment
• Key Legacy Issues - High leakage and failure risk - Poor quality of much developer-led works - Limited security and flexibility for future - Ongoing environment challenges
![Page 11: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/11.jpg)
Efficient Infrastructure – Strategy to Deliver
Asset Management Planning Approach: Regional Strategic Plans (5-6 years) and long term view Whole Life Cost (Integral Capital and Operating Budgets) Computer based records and performance models
Regional Management Approach (Economic Scale): Integrated teams and larger Schemes Common systems, management and procurement Maintain professional water services staff and skills
Adequate Budget Through User Based Charging: Revenues must cover operating and capital needs Water Metering introduced in a cost effective way Focus on encouraging demand management
![Page 12: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/12.jpg)
Efficient Infrastructure and Treatment Plants:
Modern Treatment Plants• Recent water services investment has left us with a
portfolio of new treatment plants;• Plants must have strategic capacity for future; • Maintain capital replacement funds.
Well Operated Treatment Plants• DBO contracts on treatment plants run to a
Performance Management System;• Operator and Technology Risks with the Contractor;• New standards require advanced technology and
operation.
![Page 13: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/13.jpg)
Efficient Infrastructure - Operation:
Economic Level of Leakage• Accelerate Investment in District Metering and Active
Leakage Control;• Address Customer-side Leakage as well as public mains
repairs and replacements;• Apply computer model-based asset management approach to
networks.
Energy Efficiency• Water services account for half the energy budget of most
local authorities;• Opportunities exist to use renewable energy sources and
drive energy efficiency;• Recover energy from wastewater treatment processes.

ALTERNATIVE SOURCES & STORAGE
![Page 16: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/16.jpg)
Alternative Sources/Storage – Needs for Water
• Water demands mirrors economic growth (1-2% / year)• Future Estimates – assumes leakage to below 20% and that
universal metering will apply• Rainwater/Greywater use requires bylaws and economic
incentives (low impact in medium term on existing properties)
• Must provide headroom for peak demand and risks to supply
• Ireland must use its sustainable resources to exploit worldwide water stress – key economic advantage
![Page 17: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/17.jpg)
Alternative Sources/Storage – Key Issues
• Balanced Environmental considerations – (Ecology, Amenity, Community, Climate)
• Local Catchment needs to be prioritised– Finance catchment management through abstraction charges
• Raw Water Storage – useful to avoid dry summer extractions (balancing storage)
• Desalination – High Cost / Energy – leading to significant increases in cost of water (e.g. Australia)
• Ireland must manage its water sources to achieve economic advantage
![Page 18: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/18.jpg)
Alternative Sources/Storage – Dublin & Mid East
Recommended Solution (subject to Planning)
• Lough Derg (Shannon) and large Midlands raw-water storage
• ESB balances flows at Ardnacrusha – no change in Lake levels
• Midlands Storage meets supply needs during low flow periods
• No Impact in Shannon Catchment
• Secure long-term supply will sustain vital economic growth (20/30 years and beyond)

Alternative Discharges
1.Receiving Waters dictate the discharge standards and hence costs
2.Coastal discharges offer greater capacity for large catchments
3.River / Estuarine discharges require limits on Ammonia, Phosphorus, Nitrates, Bacteria, hence higher costs
4.Treatment Plant Locations must satisfy aesthetic, odour, noise and other environmental impacts
5.Transmission networks can determine costs (Sewers, Tunnels, Pumping Systems, Urban Development)

Irish Water
“We believe that Irish Water should ultimately be a dedicated water utility company operating within a regulated
environment and with effective ownership of the assets.”
“The responsibilities of Irish Water should encompass both water and
wastewater services from abstraction of raw water through all stages of the process to the eventual discharge of
treated wastewater.”

Administration and Cost – International Water Pricing
2010 Tariffs Overview (Global Cities)
(Ref. September Issue of Water Australia)
German Cities 3.60 – 5.90 €/m3
Australian Cities 2.65 – 3.70 €/m3
Paris 2.90 €/m3
Glasgow 4.33 €/m3
US Cities 2.0 – 2.10 €/m3
Key Cost Issues:• Investing in Water Security is driving up prices, especially for Desalination• Elements of Public subsidy many apply outside EU• “Free Water” referenced in Dublin, Belfast and Ashgabat (Turkmenistan)• Current Irish consolidated charge approximately €2.30/m3
![Page 29: October 2011. Presentation Team Jerry Grant Managing Director Chartered Engineer RPS Consulting Engineers Kevin Murray Chartered Engineer Independent.](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517b2025503460e6e8b6278/html5/thumbnails/29.jpg)
Administration and Cost Model
Funding Model Required to be:
• Self Sustaining for both Capital and Operational Cost
• Raise finance backed by Regulated Asset Value
• Have transition funding for Capital needs
• Provide for legacy needs, especially leakage reduction
• Commence fixed charge and transition to metered basis in affordable
manner prioritising high leakage properties
• Social Welfare Code to provide funding for disadvantaged category

Conclusions
Ireland requires a 21st Century Water Service to further socio-economic growth
Key requirements are:
•A fit for purpose organisation to deliver, subject to policy and regulation
•Sustainable funding to meet whole life cost needs (including deficit)
•Must deliver secure high quality services with appropriate security and strategic capacity to promote growth and jobs
