Omagh Wastewater Treatment Plant, Newtownstewart, Northern Ireland

The Omagh wastewater treatment plant is located in Newtownstewart, County Tyrone, Northern Ireland, serving a population of around 38,720. As part of the United Kingdom's wastewater infrastructure, it plays a key role in managing municipal sewage for this community in the Derry and Strabane District. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), which the UK has transposed into national law, treatment plants serving agglomerations of this size are required to provide secondary treatment as a minimum. The treated effluent is discharged into local watercourses that ultimately drain into the Foyle River system and then into Lough Foyle, an ecologically important estuary on the north coast of Ireland. This water body supports diverse aquatic life and is a key migratory corridor for salmon and eels.

The plant discharges into the Foyle River catchment, which flows into Lough Foyle, a large estuary on the north coast of Ireland. Lough Foyle supports important fisheries, including Atlantic salmon and sea trout, and provides habitat for migratory birds. The estuary is ecologically sensitive, and the plant's operations are regulated to protect water quality in this downstream environment.
