SEDGEFIELD STW Wastewater Treatment Plant, Sedgefield, County Durham

SEDGEFIELD STW is a wastewater treatment plant located in Sedgefield, County Durham, in the North East of England. The plant serves a population of around 4,875 people, placing it in the small agglomeration category under UK regulations. It is situated inland, more than 50 km from the coast, and discharges into local watercourses. As a UK wastewater treatment plant, SEDGEFIELD STW operates under the Water Industry Act 1991 and the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant's treated effluent is discharged into the local river system, which ultimately drains into the North Sea via the River Tees or its tributaries. The receiving water bodies support diverse aquatic life and are important for regional biodiversity. The plant plays a key role in protecting water quality in the area, particularly given the ecological sensitivity of the Tees catchment.

SEDGEFIELD STW discharges into local watercourses that feed into the River Tees catchment, which flows eastward to the North Sea. The Tees estuary and downstream areas support diverse aquatic habitats, including migratory fish species and important bird populations. The plant's operation helps maintain water quality in this ecologically significant river system.
