Leakage Reduction Programme continues across the capital with essential upgrades underway in Dublin 2

340 metres of aged cast iron water mains to be replaced on D'Olier Street

Securing the water supply in Dublin 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.

This project is being delivered as part of Uisce Éireann's national Leakage Reduction Programme which continues to deliver significant benefits to communities across Ireland, including improved water quality, a sustainable water supply for customers, and considerable water savings.

Works are currently underway to replace 340 metres of ageing water pipes between the junction of D'Olier Street and Burgh Quay to the junction of D'Olier Street and Fleet Street, representing a significant investment by Uisce Éireann. The project once complete, will significantly reduce the amount of drinking water lost through leakage and improve water quality for homes and businesses in Dublin 2.

The works will also involve laying new water service connections from the public water main in the road to customers' property boundaries and connecting it to the customers' water supply.

Highlighting the importance of these upgrades, Declan Healy, Programme Manager at Uisce Éireann said, "We are delighted to announce the commencement of this major investment that will benefit homes and businesses in Dublin 2. Replacing these old and damaged water mains is a first step in tackling bursts, and leakage issues which have been affecting homes and businesses."

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

To facilitate the safe delivery of the project, areas of work will be limited to short sections to minimise the impact on customers and traffic management will be in place during this time in the form of a lane closure. Details will be communicated locally, and local and emergency traffic will always be maintained.

The works will be carried out on behalf of Uisce Éireann by GMC Utilities Group Ltd and are expected to be completed by the end of February 2024. 

This project forms part of Uisce Eireann's National Leakage Reduction Programme and will help us achieve our 2030 goal of a national leakage rate of 25%. The National Leakage Reduction team has made great strides since 2018 when the leakage rate stood at 46%.
