Irish Water is starting work this week to improve the water supply in areas in south and north Sligo.
The work will take place in the Ballymote and Mullaghmore areas.
Irish Water says the purpose of the works in Camross, Ballymote, and Bunduff, Mullaghmore, is to improve water quality and security of supply, as well as to reduce leaks.
Almost two kilometres of old water pipes will be replaced by modern plastic pipes on the Templehouse Road at Camross
About 380 metres of piping will be replaced at Bunduff along a local side road off the N15.
The works will also involve laying new connections from the public water main along the public road to the customer’s property boundaries and connecting it to the customer’s supply.
Existing connections on public property made of lead will be replaced.
The work will be carried out by Farrans Construction Ltd on behalf of Irish Water, and is expected to be completed by March.
