Water Conservation in Galway City & Waternomics

  1. 1. } Galway City Council Water Supply Background } Water Conservation Challenges } Leakage Reduction Activities } Galway City Council Activities } Waternomics and GCC Interface } Customer Engagement } European Green Leaf 2017 } Slow the Flow Campaign } Benefits of Water Conservation
  2. 2. • Galway City Water supply is served via Terryland Water Treatment Plant and treated imported water from Galway County Council. • Currently supplying 43,000m3 of water per day to 4 no. zones – Tonabrocky, Clifton Hill, Coolagh and Briar Hill. • Distribution Network consists of 460km of Pipework. • Since 1st January 2014, GCC work in partnership with Irish Water which is now the National Water Services Authority under the terms of a Service Level Agreement to provide Water Services. Galway City Water Background
  3. 3. Water Conservation Challenges High Leakage Levels Critical Headroom Issues Higher Operating Costs 50% DMA Operability Lack of Accurate Data Varying Leakage Estimates Low Pressure Issues Unplanned Interruptions to Supply Inconsistent Customer Service Levels 4
  4. 4. Leakage Reduction Activities 5 District Metering Programme Standardise Leakage Data and Water Management Systems Active Leakage Control: finding and fixing leaks Pressure Management Mains Replacement Customers Advice and Information
  5. 5. GCC Leakage Reduction Activities • Galway City Council has for many years been working in these keys areas of water conservation • Installing and maintaining DMA’s • Developing Leakage Detection and Repair capabilities • Replacing oldest and poorly performing watermains 6
  6. 6. } established 82 District Meter Areas installation of 300 sluice valves } 76 flowmeters. } Telemetry Logging and Water Management System has been established to relay data from the flowmeters back to the Water Conservation Team. } Hydraulic Model for the city Geographical Information System and includes asset data and comprehensive maps of the network.

  8. 8. • Analysis of the flow and pressure data gathered for each DMA • Identify and prioritise areas for Active Leakage Control • GCC have a dedicated Leak Detection crew and Repair crew .
  9. 9. } Only so much Finding and Fixing can be done before it becomes more economical to rehabilitate/replace the main. } Currently we have a project to rehabilitate almost 20km of prioritised watermain in various locations throughout the city. This project is being progressed with Irish Water at a cost of approximately €7.2 million.
  10. 10. } Presently we are finalising contract documents with Irish Water for procurement of a contractor } Due to commence on site in August 2017 } Expected Completion date February 2019
  11. 11. } Reduce existing levels of Unaccounted for Water (currently 53% to 49% upon completion of the Rehab which equates to a possible saving in operating costs of approximately €1million per year) } Improve hydraulic capacity & performance of the distribution network } Improve Security of Supply
  12. 12. } Water Conservation is NOT a project. } MUST be a consistent part of Water Operations } MUST maintain our DMA’s and Water Management Systems } MUST continually Find & Fix Leaks } MUST prioritise areas of watermain in need of Rehabilitation/Replacement.
  13. 13. } Waternomics Definition: A blend of Water and Economics: Branch of knowledge concerned with the REDUCTION in production, consumption and transfer of water. } Need to make people aware of preserving our resource. } To do this people must be aware of their usage at home, at work, at school. } Waternomics is a platform for doing this. } Raising awareness amongst consumers is recognized as essential to demand management.
  14. 14. } Assist with collection of water data } GCC can aid in identifying Usage Cases as well as possible pilot cases. } Engaging with Stakeholders } Promote the use of the Waternomics Apps, Dashboards and Fault Detection and Diagnosis } Promote Waternomics in our Domestic Customer Engagement Campaigns
  15. 15. } Be water smart } Think Before You Flush Campaign } Irish Water and Green-Schools Partnership } Report a Leak } From Cloud to Glass } From Drain to Sea } Slow the Flow
  16. 16. } The European Green Leaf is a new competition launched by the European Commission aimed at cities and towns, with between 20,000 and 100,000 inhabitants, that recognizes a commitment to better environmental outcomes. } On 22nd June 2016, Galway City was awarded the designation of European Green Leaf 2017. It is the first Irish city to be awarded this designation
  17. 17. } The objectives are threefold: } Environment Education and Awareness } To encourage public participation and citizen engagement } "green ambassador“ to encourage sustainability
  18. 18. } The Themes are: } Climate Change and Energy Performance } Mobility } Biodiversity and land use } Air quality and acoustic environment } Water and Wastewater management
  19. 19. } ‘Slow the Flow’ is a water conservation campaign initiated by Galway City Council. } It concerns reducing our daily use of treated water at home, at work and at school to an amount that is sufficient for our needs. } Your role in slowing the flow of water is very important for Galway. } Each person uses approximately 150 litres of water per day of which only about 3% is consumed as drinking water. } Conserving water is very easy to do and new habits adopted by you to avoid wasting water can become a routine part of daily life. }
  20. 20. } Saves money } Protects drinking water resources } Minimizes water pollution and health risks } Reduces the need for costly water supply and new wastewater treatment facilities } Maintains the health of aquatic environments } Saves energy used to pump, heat, and treat water and wastewater } Reduces the volume of wastewater generated for treatment
  21. 21. 840km of watermains replaced to date 70 Million Litres/Day saved to date 77% DMA Operability Leakage & Asset Data Improving Positive Customer Experience
  22. 22. } Water Conservation Infrastructure is only half the equation. } Water Conservation Infrastructure + demand management via awareness= Sustainable Use of water resources } This takes the commitment and participation of all the community } Every drop counts, every contribution matters, no matter how big or small } Make Water Conservation a Way of Life.
