Mountmellick Water Mains Replacement
Uisce Éireann replaced aged water mains in Mountmellick, Co. Laois to provide a more reliable water supply, reduce high levels of leakage and improve water quality.
The works involved the replacement of nearly 400m of aged cast iron water mains with new modern pipes. The programme to replace the water mains in Mountmellick commenced at the beginning of June. These works were being carried out as part of Uisce Éireann’s National Leakage Reduction Programme.
The section of works took place along the R422, Parnell Street, between Pearse Street to Connolly Street, Mountmellick, Co. Laois.
The works also involved laying new water service connections from the public water main in the road to customers’ property boundaries and connected it to the customers’ water supply.
The works were carried out on behalf of Uisce Éireann by Shareridge and were completed in August 2025.
