Church Hanborough Church Hanbo STW - West Oxfordshire Wastewater Treatment Plant

Church Hanborough Church Hanbo STW is a wastewater treatment plant located in West Oxfordshire, Oxfordshire, England. It serves a population of approximately 6,510 people, placing it in the small-to-medium agglomeration category under UK regulations. The plant operates under the UK's Urban Waste Water Treatment Regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, secondary treatment is typically required unless the receiving waters are designated as sensitive areas, which may necessitate more advanced treatment. The treated effluent is discharged into local watercourses that ultimately drain into the River Thames catchment. The Thames flows through southern England into the North Sea via the Thames Estuary. The local watershed supports diverse aquatic life and is important for water quality in the wider Thames basin.

The plant discharges into the River Thames catchment, which flows through Oxfordshire and eventually reaches the North Sea via the Thames Estuary.
