Drimnagh Water Main Replacement

National Leakage Reduction Programme

Uisce Éireann, in partnership with Dublin City Council, is replacing ageing water mains in Drimnagh, Dublin 12 to provide a more reliable water supply, improve water quality and reduce high levels of leakage.

These works are being carried out as part of Uisce Éireann's National Leakage Reduction Programme. The works will take place along Galtymore Road, Cooley Road, Kilworth Road, Comeragh Road, Mourne Road and Mangerton Road. The works will be carried out on behalf of Uisce Éireann by GMC Utilities Group Ltd. and are expected to be completed by early October 2019.
