Glengarriff Water Treatment Plant Upgrade

Irish Water has completed works to upgrade the water treatment plant in Glengarriff, Co. Cork to benefit over 350 customers supplied by the Glengarriff water supply scheme.

Irish Water, working in partnership with Cork County Council, has completed an upgrade of the Glengarriff Water Treatment Plant. This project will benefit over 350 customers, ensuring the delivery of a clean, safe drinking water source and removal of the area from the EPA’s Remedial Action List (RAL).

The water treatment processes at the plant were inadequate in protecting against the formation of elevated concentrations of Trihalomethanes (THMs) and Cryptosporidium. The completed upgrades have modernised and improved the water treatment process at the plant. The works were delivered by Glan Agua Limited on behalf of Irish Water.
