Overview
Tuam Waste Water Treatment Plant serves 21,400 people in County Galway, Ireland. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
Tuam Waste Water Treatment Plant is a municipal facility located in the Tuam Rural Electoral Division, County Galway, Ireland. Serving a population of 21,400, it is classified as a medium agglomeration under Irish and EU regulations. The plant is situated inland in the Connacht region, approximately 50 km from the coast. As an Irish wastewater treatment plant, Tuam operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent discharging into fresh water or estuaries. Irish plants are regulated by the Environmental Protection Agency (EPA) under the Waste Water Discharge (Authorisation) Regulations. The treated effluent from Tuam likely discharges into the River Clare or its tributaries, which flow into Lough Corrib and eventually to Galway Bay on the Atlantic coast. The plant plays a key role in protecting the water quality of the Corrib catchment, a region known for its salmon and trout fisheries and ecologically sensitive lakes.
Environmental context
The plant discharges into the River Clare catchment, which drains into Lough Corrib, one of Ireland's largest lakes, and then into Galway Bay. The Corrib system supports diverse aquatic life, including Atlantic salmon, sea trout, and the endangered freshwater pearl mussel. The bay is a designated shellfish water and supports important marine habitats. Protecting water quality in this catchment is critical for both ecological health and local tourism and fishing industries.
