Caragh Lake Water Treatment Plant Upgrade

Water Project

Uisce Éireann is upgrading the water treatment plant at Caragh Lake to provide a clean and safe water source to customers in the area.

Uisce Éireann, working in partnership with Kerry County Council, is completing works to improve the quality of water for the Caragh Lake Water Supply Scheme in West Kerry. This investment will benefit over 1,800 customers, ensuring the delivery of a clean, safe drinking water source.

The existing water treatment process at the plant was inadequate due to the formation of elevated concentrations of Trihalomethanes (THMs) and other contaminants above the drinking water standards. The water treatment system at the plant is being upgraded to improve the drinking water quality for the area. This project is being delivered by EPS Group Limited on behalf of Uisce Éireann.
