Removal follows upgrade of water treatment plant in Kilgarvan

Irish Water in partnership with Kerry County Council is pleased to confirm that an additional 785 customers in Co. Kerry have been removed from the EPA’s Remedial Action List following the completion of upgrade work and on the water treatment plant in Kilgarvan.

This €0.5 million investment in the Kilgarvan water treatment plant involved the provision of a 500m³ reservoir and the installation of in-tank aeration, thereby addressing issues with trihalomethanes (THMs) in the supply.

EPA's Remedial Action List 

The EPA’s Remedial Action List or RAL is the list of ‘at risk’ water supplies. The Kilgarvan supply was on the RAL due to elevated levels of trihalomethanes (THMs).

“Irish Water has a prioritised programme of investment for all schemes on the RAL. The current updated RAL shows a reduction from 11 to three schemes in Kerry which is a reflection of the progress we are making” said Ian O’Mahony, Irish Water’s Water Lead for Kerry.

“Upgrade works on the remaining three – the Caherdaniel, Castlecove and Caragh Lake - water treatment plants is currently underway. These upgrades should facilitate the removal of these schemes from the RAL.”


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 aim 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.

“As a single utility Irish Water can take a comprehensive look at the overall performance of Ireland’s drinking water production plants for the first time so that when the most serious problems are identified, projects and budgets can be prioritised” added Ian O’Mahony.
