WINCHCOMBE STW - Secondary Wastewater Treatment Plant in Tewkesbury, England

WINCHCOMBE STW is a wastewater treatment plant located in Tewkesbury, Gloucestershire, England. It serves a population of approximately 4,446 people, classifying it as a small agglomeration under UK water industry standards. The plant is situated inland, away from coastal areas, and its operations are part of the broader water management infrastructure for the region. The plant provides secondary treatment, which is the standard biological treatment process required for inland freshwater discharges under the EU Urban Waste Water Treatment Directive (91/271/EEC), as retained in UK law. With a designed capacity of 5,500 cubic meters per day and an average discharge volume of 989.83 cubic meters per day, the plant operates well within its capacity, ensuring effective treatment of incoming wastewater. The treated effluent is discharged into a local watercourse, likely a tributary of the River Isbourne, which flows into the River Avon and eventually the River Severn. This river system supports diverse aquatic life and is an important ecological corridor in the Severn Basin. The plant's secondary treatment helps protect water quality in these downstream environments.
