Carnamuggagh Water Mains Replacement
Uisce Éireann, in partnership with Donegal County Council, replaced ageing, problematic water mains prone to bursts in Carnamuggagh, Letterkenny, Co. Donegal to provide a more secure and reliable water supply and reduce high levels of leakage.
The works involved replacement of approximately 900m of aged problematic water mains with new modern pipes. The project which replaced the water mains in Carnamuggagh, Letterkenny, Co. Donegal commenced in early July 2023. These works were carried out as part of Uisce Éireann's National Leakage Reduction Programme.
The section of works took place along the N56 and L1164 Carnamuggagh Lower Road. In order to minimise disruption a phased approach with areas of works limited to short sections were adopted for delivery of this project.
The phases facilitated works along the N56 and L1164 Carnamuggagh Lower Road.
The works were carried out on behalf of Uisce Éireann by Farrans Construction and were completed by May 2025.
