WOODSTOCK OXON STW - Secondary Wastewater Treatment in West Oxfordshire, England

WOODSTOCK OXON STW is a wastewater treatment plant located on Green Lane in Woodstock, West Oxfordshire, Oxfordshire, England. It serves a population of approximately 3,720 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated inland, away from coastal areas, and its operations are part of the region's municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 3,772 m³/day, and the current discharge volume is 828.20 m³/day, indicating operational headroom. As a UK facility, it operates under environmental permits issued by the Environment Agency, which set discharge consent conditions to protect receiving water quality. The treated effluent is discharged into local rivers that ultimately drain into the River Thames catchment, contributing to the Thames Basin. This waterway supports diverse aquatic life and is used for recreation and water supply downstream. The plant's secondary treatment helps reduce organic pollutants and suspended solids, safeguarding the ecological health of the receiving waters.

The plant discharges into the River Thames catchment, which flows through Oxfordshire and into the Thames Estuary. The receiving waters support a range of fish species, including coarse fish and salmonids, and are important for local biodiversity. The plant's secondary treatment helps maintain water quality in this sensitive river system, which is also used for drinking water abstraction and recreation downstream.
