COTON PARK STW - Secondary Wastewater Treatment in South Derbyshire, England

COTON PARK STW is a wastewater treatment plant located in South Derbyshire, England, within the East Midlands region. It serves a population of 4,340 and is part of the United Kingdom's municipal wastewater infrastructure, operating under the regulatory framework of the UK Environment Agency. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC), transposed into UK law. With a designed capacity of 6,000 m³/day and an average discharge volume of 966.23 m³/day, the facility operates well below its capacity, indicating headroom for future growth or seasonal variations. The treated effluent is discharged into local watercourses that drain into the River Trent catchment, ultimately reaching the North Sea via the Humber Estuary. The plant plays a role in protecting the ecological quality of the River Trent and its tributaries, which support diverse aquatic life and are important for regional biodiversity.

The plant discharges into the River Trent catchment, which flows into the Humber Estuary and then the North Sea. The River Trent is a major river in the East Midlands, supporting a variety of fish species and aquatic habitats. The secondary treatment provided helps reduce organic pollution and nutrient loads, contributing to the ecological health of downstream waters, which are important for both wildlife and recreational use.
