Wath on Dearne Brampton STW - Barnsley Wastewater Treatment Plant, England

Wath on Dearne Brampton STW is a wastewater treatment facility located on Dearne Road in Bolton upon Dearne, Barnsley, South Yorkshire, England. The plant serves a population of around 18,247 people, placing it in the medium agglomeration category under UK and EU regulatory frameworks. As a plant serving a medium-sized community, it is expected to meet secondary treatment standards under the Urban Waste Water Treatment Directive (91/271/EEC), which applies to all significant discharges in the United Kingdom. The facility is part of the national wastewater infrastructure managed by water utilities under the regulatory oversight of the Environment Agency. The plant discharges treated effluent into the local water environment, ultimately contributing to the River Dearne, a tributary of the River Don. The River Don flows through South Yorkshire and joins the River Ouse, eventually reaching the Humber Estuary and the North Sea. This catchment supports diverse aquatic life and is important for regional biodiversity.

The plant's treated effluent enters the River Dearne, which flows into the River Don, a key watercourse in South Yorkshire. The Don then joins the River Ouse, leading to the Humber Estuary, a major ecological site supporting migratory birds and fish. The catchment area is influenced by both urban and agricultural runoff, making effective wastewater treatment crucial for maintaining water quality and protecting downstream habitats.
