Rathvilly Water Treatment Plant Upgrade

Irish Water has commenced works to upgrade the water treatment plant in Rathvilly, Co. Carlow to benefit over 15,000 customers.

Irish Water, working in partnership with Carlow County Council, has commenced an upgrade of the Rathvilly Water Treatment Plant. This project will benefit over 15,0000 customers, ensuring the delivery of a clean, safe drinking water source.

The Carlow North Regional Water Supply is included on the Environmental Protection Agency’s (EPA’s) Remedial Action List (RAL), which identifies water supplies that are in need of improvement. Currently, there is inadequate protection against microbiological failure and the potential formation of elevated concentrations of Trihalomethanes (THMs).

The completed upgrades will modernise and improve the water treatment process at the plant, ensuring raw water is treated to the water quality standards as required by the European Union Council Directive and Regulations. Glan Agua Limited is delivering the project on behalf of Irish Water.
