Uisce Éireann working to restore Lough Mourne Public Water Supply

19 January 2024

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

Uisce Éireann is working to restore normal water supply to homes and businesses served by the Lough Mourne Public Water Supply Scheme following an unplanned plant shut down at the Meencrumlin Water Treatment Plant due to an electrical issue. As a result, water production at the treatment plant is impacted and some customers will experience reduced water pressure and/ or outages.

Crews are on the ground working to restore normal water supply as quickly as possible to impacted customers. 

In the meantime, customers in Ballybofey and Stranorlar, Glenfin, Liscooley Group Water Scheme, Rossgier to Porthall and Rossgier to Cavan Hill and customers served by the Tievebrack, Ballynacor and Gleneely/Lismullaghduff Reservoirs may experience reduced water pressure and/ or water outages today. 

Paul Kilcoyne, Operations Lead for Uisce Éireann said: "We understand the inconvenience this is causing and are currently investigating the issue to restore normal water supply as quickly as possible. Once normal operations are restored, it will take time for the network to refill and normal supply to return to all customers. 

“We are also asking the public to do what they can to conserve water during this time by turning off taps and checking for leaks in outside taps or unoccupied premises. If anyone notices a leak in the public network they should report it to Uisce Éireann via or by calling 1800 278 278.
