WINSLOW STW - Winslow, Buckinghamshire Wastewater Treatment Plant

WINSLOW STW is a municipal wastewater treatment plant located in Winslow, Buckinghamshire, England. Serving a population equivalent of approximately 5,932, the facility is part of the UK's wastewater infrastructure managed under the Water Industry Act 1991 and the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). As a plant serving a small agglomeration (under 10,000 population equivalent), the regulatory framework requires secondary treatment or equivalent, with appropriate nutrient removal if discharging into sensitive areas. The facility is expected to comply with the relevant discharge permits issued by the Environment Agency. The plant discharges treated wastewater into local watercourses that ultimately drain into the River Great Ouse, which flows through Buckinghamshire and Cambridgeshire before entering The Wash, a large tidal estuary on the North Sea. The Great Ouse catchment supports diverse aquatic habitats and is important for migratory fish species such as salmon and eel.

WINSLOW STW discharges into the River Great Ouse catchment, which flows through the low-lying landscape of Buckinghamshire and Cambridgeshire before reaching The Wash, a major North Sea estuary. The Great Ouse supports a variety of freshwater and estuarine habitats, including wetlands and floodplain meadows that provide critical breeding and feeding grounds for waterbirds and fish. The Wash is an ecologically sensitive area, designated for its importance to migratory birds and marine life.
