Ballycastle Water Supply Scheme

Water Project

Irish Water has upgraded the drinking water supply for the Ballycastle area in Mayo.

Irish Water, working in partnership with Mayo County Council, has completed upgrade works to the Ballycastle Water Supply Scheme. This project has benefitted over 360 customers in the Ballycastle area to ensure the delivery of a clean, safe drinking water source and facilitated the removal of the area off the EPA’s Remedial Action List (RAL).

The project consisted of the installation of 6km of pipeline in order to connect the Ballycastle water supply scheme to the Ballina Regional Water Supply Scheme. This project has improved the drinking water quality for Ballycastle and surrounding area. The works were carried out by Source Civil Limited on behalf of Irish Water.
