Crews replacing over 1300m of aged watermains in Killiney Heath

Securing the water supply in Dun Laoghaire-Rathdown remains a top priority for Uisce Éireann as the intensive campaign continues to drive down leakage and improve the water supply to homes and businesses.

These projects continue to be delivered as part of Uisce Éireann's national Leakage Reduction Programme which is delivering significant benefits to local communities across Ireland including improved water quality, a more secure water supply, and considerable water savings.

Working in partnership with Dun Laoghaire-Rathdown County Council, Uisce Éireann is replacing over 1300m of old and damaged cast iron water mains, in Killiney Heath with new, modern pipes. The section of works will begin next week from the junction of Killiney Avenue Road and Killiney Heath Road taking in the Killiney Heath residential area.

Aged cast iron pipes over time can significantly impact water quality, leakage levels, and pressure. Replacing these old, damaged pipes with new, modern pipework will greatly reduce the instances of bursts, outages, and low-pressure affecting customers.

Highlighting the importance of these upgrades, Matt Thomson, Leakage Reduction Programme Regional Lead with Uisce Éireann, said, "We are delighted to announce this significant investment for Killiney Heath. Replacing these old and damaged pipes is a first step in tackling water pressure and leakage issues which have been affecting homes and businesses. The works will not only reduce the amount of drinking water lost to leakage, but it will also deliver a much more reliable supply for generations to come."

"To minimise the impact on the local community, we are delivering these works on a phased basis with areas of work limited to short sections."

Matt added "On behalf of Uisce Éireann, I would like thank the local community in advance for their patience and cooperation as traffic management will be necessary as the project progresses, however, based on previous experiences, we know that the short-term inconvenience will be overshadowed by the long-term benefits."

The works also involve laying new water service connections from the public water main in the road to customers' property boundaries and connecting it to the customer's water supply. The works may involve some short-term supply interruptions which we understand may cause inconvenience, however, the project team will ensure that customers are given a minimum of 48 hours' notice prior to any planned water interruptions. The project is being delivered on behalf of Uisce Éireann by GMC Utilities Group and is expected to be completed in December 2022.  

Fixing leaks can be complicated but we are making progress. In 2018 the rate of leakage nationally was 46%, by the end of 2021 it was reduced to 38%.  We are on track to achieve a national leakage rate of 25% by the end of 2030.
