Improvements following completion of Irish Water upgrade works

Water consumers in the Cashelard area of Co. Donegal are enjoying an improved water supply following an investment of €150,000 by Irish Water in the upgrade of the existing treatment plant.

The upgrade was carried out by Donegal County Council operations and maintenance staff and was completed over a four week period.

The project included the provision of an additional treatment process to the existing plant to improve the quality of the drinking water.

The Cashelard supply is on the Environmental Protection Agency’s (EPA) Remedial Action List (RAL) for high levels of THMs and these works were undertaken to reduce the risk posed by THMs for these customers.

Irish Water’s Capital Programme Lead, Martin Temple, said “These important works for the Cashelard Water Treatment Plant have just been completed and consumers in the area are now being supplied with an improved water quality where the risk of THMs has been reduced.”

Irish Water has put in place the first national THM plan and a prioritised programme of investment to address all inadequacies in drinking water parameters including THMs. By 2021, we plan to reduce the number of schemes on the RAL to zero with an investment of €327 million in upgrading water supplies at risk from THMs.

THMs, or trihalomethanes, are chemicals formed by the reaction of naturally occurring dissolved organic material with chlorine which is used for disinfection in order to protect against pathogenic bacteria.

This project forms part of Irish Water’s investment plan where works have been prioritised to address the most critical issues in line with commitments outlined in Irish Water’s business plan. Delivery of the business plan will involve a €5.5bn investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021.
