HATHERSAGE STW - Closed Secondary Wastewater Treatment Plant in Derbyshire Dales, England

HATHERSAGE STW (Sewage Treatment Works) is located in Hathersage, Derbyshire Dales, in the East Midlands of England. The plant was designed to treat wastewater from the local population, with a capacity of 1803 cubic meters per day, and provided secondary treatment before its closure. As a secondary treatment facility, HATHERSAGE STW would have met the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for discharges to freshwater and estuaries. The plant's closure may reflect upgrades or consolidation of regional wastewater infrastructure. The plant's treated effluent would have been discharged to a local watercourse, likely the River Derwent, which flows through the Peak District and eventually joins the River Trent. This river system supports diverse aquatic life and is important for regional water quality.

HATHERSAGE STW discharged into the River Derwent catchment, part of the Humber River Basin. The Derwent flows through the Peak District, an ecologically sensitive area supporting salmonid fish and other freshwater species. Downstream, the river joins the Trent, which drains into the Humber Estuary, a major migratory corridor for birds and fish.
