Oadby STW - Wastewater Treatment Plant in Oadby and Wigston, Leicestershire

Oadby STW is a wastewater treatment plant located in Oadby, Leicestershire, serving the Oadby and Wigston urban area. The facility treats wastewater from a population equivalent of around 20,279, placing it in the medium agglomeration category under UK regulatory frameworks. The plant is situated inland, away from coastal waters, and discharges into local watercourses that feed into the River Soar catchment. As a UK wastewater facility, Oadby STW operates under the Urban Waste Water Treatment (England and Wales) Regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, secondary treatment is typically required, with additional nutrient removal if discharging into sensitive areas. The plant's treatment processes are designed to meet these standards, ensuring compliance with environmental permits issued by the Environment Agency. The treated effluent from Oadby STW ultimately enters the River Soar, a tributary of the River Trent, which flows into the Humber Estuary and the North Sea. The River Soar supports diverse aquatic life and is used for recreation. The plant plays a key role in protecting water quality in this river system, reducing nutrient and pollutant loads that could otherwise impact downstream ecosystems.

Oadby STW discharges into local watercourses that drain into the River Soar, a major tributary of the River Trent. The River Soar flows through Leicestershire and joins the Trent near Nottingham, eventually reaching the Humber Estuary and the North Sea. This catchment supports a variety of fish species and aquatic habitats, and the plant's treatment helps maintain water quality standards for ecological health and downstream uses.
