Overview
Chinnor Chinnor Oxon STW is a wastewater treatment plant serving approximately 7,640 people in South Oxfordshire, England. It operates under UK regulations implementing the EU Urban Waste Water Treatment Directive.
Chinnor Chinnor Oxon STW is a wastewater treatment plant located in South Oxfordshire, England, serving a population of around 7,640. The plant is situated near the village of Chinnor in Oxfordshire, part of the Thames River basin. As a small agglomeration under the EU Urban Waste Water Treatment Directive (transposed into UK law), the plant is expected to provide at least secondary treatment to meet environmental standards. The UK Environment Agency oversees permitting and compliance for such facilities, ensuring discharges protect local water quality. The treated effluent from the plant likely discharges into a local watercourse that feeds into the River Thame, a tributary of the River Thames. The Thames eventually flows into the North Sea via the Thames Estuary, supporting diverse aquatic ecosystems and providing water resources for the region.
Environmental context
The plant discharges into a local watercourse within the Thames River basin, which drains through the River Thame and River Thames to the North Sea. The Thames Estuary is an ecologically important area supporting migratory fish, bird populations, and diverse aquatic life. The plant's treatment helps protect downstream water quality in this sensitive river system.
