Billingham STW - Hartlepool, England Wastewater Treatment Plant

Billingham STW is a wastewater treatment plant serving the Hartlepool area in Tees Valley, England. It handles wastewater from a population of around 33,605, placing it in the medium agglomeration category under UK regulations. The plant operates under the UK's transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries from agglomerations of this size. The designed capacity is 1.00 (likely in megalitres per day or similar unit), indicating a facility scaled to handle the local population's wastewater. The treated effluent is discharged into the Tees River catchment, which flows into the North Sea. The Tees Estuary supports diverse aquatic life and is an important area for migratory birds. The plant's location within 50 km of the coast means its discharge contributes to the overall water quality of the North Sea coastal environment.

The plant discharges into the River Tees catchment, which flows into the Tees Estuary and then the North Sea. The Tees Estuary is an ecologically sensitive area that supports diverse aquatic life, including fish and bird species. The North Sea receives the final discharge, and the plant's nutrient removal helps protect against eutrophication in coastal waters.
