Irish Water, working in partnership with Donegal County Council, is replacing approximately 281 metres of problematic, old water mains in Main Street, Laghey,
The pipes were prone to frequent bursts and leakage and caused water supply disruptions for customers in the area.
Old cast iron water mains are being replaced with new high density plastic pipes.
The works are due to be completed by the end of August.
Farran’s Construction Ltd are contracted to carry out the work on behalf of Irish Water.
