WARMSWORTH STW - Doncaster Wastewater Treatment Plant, England

WARMSWORTH STW is a wastewater treatment plant located in Warmsworth, Doncaster, South Yorkshire, England. It serves a population of around 11,231 residents, classifying it as a medium-sized agglomeration under UK regulations. As a plant in England, WARMSWORTH STW is subject to the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. For agglomerations of this size, secondary treatment is typically required, with additional nutrient removal if discharging into sensitive areas. The plant's treated effluent likely discharges into a local watercourse that flows into the River Don, part of the Humber River Basin. The River Don eventually reaches the Humber Estuary, a major ecological site supporting diverse aquatic life and migratory birds.

WARMSWORTH STW discharges into the River Don catchment, which drains into the Humber Estuary. The Humber Estuary is a large tidal estuary that supports important fish populations, including salmon and sea trout, and provides habitat for overwintering waterbirds. The plant's operations help protect water quality in this ecologically significant downstream environment.
