Blackrock community to benefit from improved, more dependable water supply

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 Cross Avenue, Blackrock, Co. Dublin.

Between Booterstown Avenue/Cross Avenue Junction and the N31/Cross Avenue Junction, our crews will be installing over 764 metres of new, modern pipes that will 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. 

The upgrades will also support future growth and development in the area by increasing network capacity and ensuring the water infrastructure can meet the demands of a growing community.

Welcoming the project, Mark O’Duffy of Uisce Éireann said that this upgrade will help stop leakage and give the community in the Blackrock area greater confidence in their water supply for years to come. This investment will also help to ensure there is sufficient capacity to support future housing and development in the area.

“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 will begin in late September 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 in early 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.
