Blackrock to benefit as works begin on improved water quality and a more secure supply

Information below is relevant until further updates are provided here or on our Supply and Service Updates section

At Uisce Éireann, we’re committed to providing a reliable water supply for everyone in the community. To help make that happen, we’re getting underway with works to replace old and damaged water mains in Blackrock, Co Dublin.

Our crews will be installing over 1km of new, modern pipes along Mount Merrion Avenue, Sydney Avenue, Anglesea Avenue and Frascati Park which will improve water quality, strengthen the local network and reduce disruption to homes and businesses.
The existing pipes were prone to bursts and leaks, leading to supply interruptions and the loss of treated drinking water, a valuable resource we all depend on. 

Welcoming the project, Nicola Butler of Uisce Éireann said that these upgrades will help stop leakage and give the community in Blackrock greater confidence in their water quality and supply for years to come. 

“Every pipe we replace is guided by one clear goal: providing a water supply people can count on. These improvements make a difference every single day, in every tap, home and throughout the community. By focusing on delivering a more reliable supply, we’re helping to build a stronger, more resilient water service for the people of Blackrock now and for generations to come.” 

Works are underway and will include installing new water service connections from the public water main on the road to customers’ property boundaries and linking them to the customers’ water supply. 

The project is being delivered by GMC Utilities Ltd. on behalf of Uisce Éireann with completion expected by Q2 2027. 

Customers can phone Uisce Éireann on 1800 278 278 if they have any questions about the project or visit the Water Supply Updates section of our website for regular updates.

We have measures in place to keep disruption to an absolute minimum but to protect the public and our crews, a traffic management system will be in place during the works. Local and emergency traffic will always be maintained. 

This project is one example of how Uisce Éireann works every day to reduce leaks. With more than 65,000 km of underground pipes nationally- enough to circle the earth one and a half times - fixing leaks can be complicated. Many are hidden, but we are making progress: National leakage is now at its lowest level ever, reduced from 49% in 2014 to 36% today.
