Irish Water and Donegal County Council have issued an apology to residents of Falcarragh, Gortahork and surrounding areas who were without a water supply following an electrical fault at the Ardsbeg water treatment plant.
Homes and businesses had their supply cut from last night to early this morning as a result of the fault.
The issue is now resolved after crews worked on repairs through the night.
Residents have been advised it may take a few hours this morning for a full supply to return to all customers. Any customers still experiencing issues later this morning can report them to the Irish Water customer care helpline on 1850 278 278.
