Elsecar Lund Hull and Wombwell STW: Barnsley Wastewater Treatment Plant

Elsecar Lund Hull and Wombwell STW is a wastewater treatment plant located in Barnsley, South Yorkshire, England. It serves a population of approximately 51,913, classifying it as a medium-sized agglomeration under UK and EU regulatory frameworks. The plant operates under the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The regulatory framework ensures compliance with discharge standards to protect receiving waters. The treated effluent is discharged into local rivers that drain into the Humber Estuary and ultimately the North Sea. The plant plays a key role in maintaining water quality in the region, supporting aquatic life and downstream ecosystems.

The plant discharges into local watercourses that flow into the River Don and then the Humber Estuary, a major ecological feature supporting diverse aquatic life and migratory birds. The Humber Estuary is a vital habitat for fish and bird species, and the plant's operations help reduce nutrient and pollutant loads entering this sensitive environment.
