} Benefits of Water Conservation

• Galway City Water supply is served via TerrylandWater 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.

• 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

} 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.

} 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

} 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

} 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.

} 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.

} 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

} 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

} 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

} The objectives are threefold:

} Environment Education and Awareness

} To encourage public participation and citizen engagement

} "green ambassador“ to encourage sustainability

} The Themes are:

} Climate Change and Energy Performance

} Mobility

} Biodiversity and land use

} Air quality and acoustic environment

} Water and Wastewater management

} ‘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.

} 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

Experience

} 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.
