Lough Mask Water Supply Scheme

Irish Water is progressing upgrade works as part of a €9million investment in the Lough Mask Regional Water Supply Scheme.

Irish Water, in partnership with Mayo County Council, is progressing plans to upgrade the Tourmakeady Water Treatment Plant (WTP) and extend the supply area of the Lough Mask Water Supply Scheme into North West Roscommon and North Galway. The project will improve the security of water supply and water quality across these areas. Veolia Water Ireland has been appointed to carry out the works on behalf of Irish Water.

These works follow on from works completed in 2018 on Lough Mask Regional Water Supply Scheme which extended supply to Ballinlough / Loughglynn and Williamstown. The project represented an investment of €10 million to ensure a clean and secure supply of drinking water for the 5,000 consumers on the two supplies. It was also responsible for the removal of the long-standing boil water notice in Ballinlough affecting 3,600 of those consumers.

What are the benefits of this project?
