Finstock Finstock Oxon STW - Secondary Wastewater Treatment in West Oxfordshire, England

Finstock Finstock Oxon STW is a municipal wastewater treatment facility located in the village of Finstock, near Charlbury, in West Oxfordshire, England. The plant serves a population of approximately 3,460 people and operates under the regulatory framework of the UK Environment Agency. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids, meeting the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC), which the UK has retained in domestic law. The plant has a designed capacity of 3,476 cubic meters per day, with a current discharge volume of 770.32 cubic meters per day, indicating it operates well below capacity. The treated effluent is discharged into local watercourses that drain into the River Evenlode, a tributary of the River Thames. The Thames eventually flows into the North Sea via the Thames Estuary. The plant plays a key role in protecting the water quality of the Evenlode and Thames, supporting aquatic life and downstream ecosystems.

The plant discharges into the River Evenlode catchment, which flows into the River Thames, a major river in southern England. The Thames Estuary and the North Sea are the ultimate receiving waters. The Evenlode supports diverse aquatic life, including fish species such as brown trout and grayling, and is an important habitat for water voles and otters. The plant's secondary treatment helps maintain water quality in this sensitive river system.
