Bear Park STW - Secondary Wastewater Treatment Plant in Durham, England

Bear Park STW (Sewage Treatment Works) is located in Bearpark, a village near Durham in County Durham, England. The plant serves a population of around 2,000 and is part of the region's wastewater infrastructure managed under UK regulations. The facility provides secondary treatment, which is the standard biological treatment required under the Urban Waste Water Treatment Directive for agglomerations of this size. The plant has a designed capacity of 2,283 m³/day and currently treats an average daily flow of 450 m³/day, indicating spare capacity. Treated effluent is discharged into a local watercourse that ultimately drains into the River Wear and then into the North Sea. The River Wear supports diverse aquatic life and is an important ecological corridor in the North East of England.

The plant's discharge enters a tributary of the River Wear, which flows eastward through Durham and Sunderland before reaching the North Sea. The River Wear supports salmon and trout populations and is designated as a Site of Special Scientific Interest in parts. The North Sea receiving environment is ecologically sensitive, with important fisheries and marine habitats.
