Twelve million euro worth of work in replacing about 40 kilometres of old water mains pipes across County Donegal is expected to be finished by the end of this year.
The work is taking place at 13 locations.
The works started last September, with the contract having been awarded to a company called ShareRidge Limited.
Among the 13 areas where work is to take place are Corker, Rossnowlagh; Abbeylands in Ballyshannon, Erne Street and St Benildus Avenue in Ballyshannon Town, and Bundoran West End.
Irish Water, which is working in partnership with Donegal County Council, says the works will also involve laying new water service connections from the public water main in the street or road to customers’ property boundaries, and connecting it to the customers’ water supply.
The project also involves the removal of what’s described as 116 backyard services in Ballyshannon Town.
Irish Water says traffic management will be in operation at all sites during the works, and residents and businesses will be notified ahead of works starting.
Ballyshannon-based Fine Gael Councillor Barry O Neill is welcoming the work but says he wants Irish Water to engage with local residents.
