Water conservation efforts continue with upgraded water mains in North Dublin

08 December 2023

As part of its commitment to provide a more sustainable water supply Dublin and the GDA, Uisce Éireann, working in partnership with Dublin City Council, is replacing over 1km of aged water mains in Harmonstown, Dublin 5 to provide the local community with a much-improved water supply.

The works, which commenced this week will take on Lein Park, Lein Road, McAuley Aveune and Harmonstown Road, and will provide a more reliable water supply and reduce the amount of treated drinking water lost to leakage. The works are a critical step in conserving our precious resource and reducing high levels of leakage which have been a significant source of disruption and outages for customers. 

Programme Manager, for Uisce Éireann’s National Leakage Reduction Programme, Declan Healy is looking forward to getting crews on site. “Aged water mains remain a huge source of leakage and continue to impact communities right across Ireland, causing low pressure and supply disruption. Replacing these old water mains in poor condition will eliminate existing leaks and significantly reduce the amount of clean drinking water lost into the ground.”

We would like to thank the community Harmonstown in advance for their patience and cooperation during the works. We know based on previous experience that the short-term inconvenience will be overshadowed by the lasting benefits.”

The works may involve some short-term interruptions to the water supply. The project team will ensure that customers are given a minimum of 48 hours-notice prior to any planned interruption. We understand that this type of work can be inconvenient. Works crews will make every effort to minimise any disruption these necessary works cause.

Where water mains are being installed, traffic management will be in place however, local and emergency access will always be maintained.

This project is being carried out GMC Utilities Group on behalf of Uisce Éireann and is expected to be completed by the end of January 2024.

The National Leakage Reduction Programme helps provide a more reliable water supply to Irish communities by reducing high levels of leakage and improving water quality. Since 2018, its delivery has represented an investment of over €500 million to upgrade the underground water network across the country through the delivery of the Leakage Reduction Programme. Uisce Éireann is also investing a further €250 million annually up to the end of 2030 directed at fixing leaks and replacing pipes to provide a more reliable water supply.
