ABINGDON STW: Closed Wastewater Treatment Plant in Sutton Courtenay, Oxfordshire

ABINGDON STW is a former wastewater treatment plant located in Sutton Courtenay, near Abingdon, in the Vale of White Horse district of Oxfordshire, England. The facility was designed with a capacity of 41,683 cubic meters per day, indicating it served a significant population in the region. As a secondary treatment plant, ABINGDON STW would have provided biological treatment to remove organic matter and suspended solids, meeting the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland waters. The plant's closure suggests that wastewater flows have been diverted to a newer or upgraded facility in the area. The plant's discharge would have entered the River Thames catchment, which flows through Oxfordshire and ultimately into the North Sea via the Thames Estuary. The Thames supports diverse aquatic life and is an important ecological corridor in southern England.

ABINGDON STW was located in the Thames River basin, with treated effluent likely discharging into a tributary of the River Thames. The Thames flows through Oxfordshire and London before reaching the North Sea. The river supports a variety of fish species, including salmon and trout, and its estuary is a critical habitat for migratory birds.
