Connecting customers in Limerick City to a more resilient water network

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

Uisce Éireann is starting works next week to build a stronger water network which supplies areas of Limerick City, by replacing ageing backyard water mains and reducing high levels of leakage in the area.  

These works will involve the replacement of over 1.1km of aging cast iron water mains and will take place along O’Donoghue Avenue, Clansfort Terrace, Glenmore Avenue and Mulgrave Street. These works are being carried out as part of Uisce Éireann’s National Leakage Reduction Programme.  
In some older estates across the country, water connections, typically made of iron or lead, were installed to the rear of properties, often referred to as backyard service connections. The pipework due to age and deterioration factors can be a significant source of leakage. Backyard water services are usually shared, running through neighbouring properties, making it difficult to detect and repair leaks. Since properties may share a connection, leaks and bursts can affect all properties in a neighbourhood which can result in low pressure. 

Commenting on the project, Programme Manager for Uisce Éireann’s National Leakage Reduction, Brian McCarthy, said: “We’re investing in the future of Limerick City with essential network upgrades that will strengthen and sustain our water infrastructure for generations. These improvements will safeguard homes and businesses, ensuring a reliable supply of clean water for years to come. 

“Ageing water mains contribute to a significant amount of leakage and by replacing them with more modern pipes, we’re reducing bursts, eliminating leaks, improving water quality, and futureproofing drinking water. We appreciate the patience and support of the local community as we work together to build a stronger, more resilient network.”  

Areas of work will be limited to short sections to minimise impact on customers. Traffic management will be in place for the duration of these works in the form of traffic lights and flagmen on O’Donoghue Avenue, Clansfort Terrace and Mulgrave Street.  

A road closure will be in place on Glenmore Avenue from 05 January – 30 January 2026. Local and emergency access will always be maintained. Traffic flows will be diverted during the duration of the closure. 

Works will commence on O’Donoghue Avenue, moving to Glenmore Avenue in the new year and completing on Mulgrave Street. 

The works may require some short-term water supply interruptions, and the project team will ensure that customers are given a minimum of 48 hours’ notice prior to any planned water interruptions.  

The works will be carried out by Ward and Burke Construction Ltd on behalf of Uisce Éireann and are expected to be completed in April 2026.
