Irish Water says it has recently completed water saving projects in a number of areas in Donegal, including Killybegs and Laghey in time for Christmas.
The water provider says that by replacing ageing water mains in these areas, it will reduce the volume of clean water being lost underground, as well as improving the reliability of water being provided to homes and businesses.
In total, close to 1km of water mains have been replaced in Donegal with new high density plastic pipes.
All lead service connections on the public roadway were also replaced as part of the works.
In Killybegs, about 350m of mains replacement was completed along the L1285 and the R263 Shore Road.
On Main Street in Laghey, about 300m of mains were replaced.
Declan Cawley, of Irish Water, said:essential works in Letterkenny, Killybegs, Stranorlar and Laghey had strengthened and reinforced the water network in County Donegal.
Irish Water has thanked the communities in all four areas for their patience during the essential works.
Michael McGroddy, assistant engineer, with Donegal County Council, said the replacement of old pipes will significantly improve water quality, safeguard the water supply and have a positive impact on leakage and the daily lives of these Donegal communities.
