Harworth STW is a wastewater treatment plant located in Harworth, near Doncaster in the East Midlands region of England. It serves a population of approximately 8,909 people, classifying it as a small to medium agglomeration under UK 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 discharges to freshwater and estuaries for populations over 2,000. For agglomerations of this scale, appropriate treatment is mandated to protect receiving water quality. The treated effluent from Harworth STW is discharged into local watercourses that ultimately drain into the River Trent catchment, a major river system flowing into the Humber Estuary and the North Sea. The plant plays a key role in protecting the ecological health of these downstream waters.
