THAME THAME OXON STW Wastewater Treatment Plant, South Oxfordshire, England

THAME THAME OXON STW is a wastewater treatment facility located on Moorend Lane in Thame, South Oxfordshire, England. The plant serves a population of around 12,700 residents, classifying it as a medium-sized agglomeration under UK water industry standards. As a plant in England, it operates under the Water Industry Act 1991 and is regulated by the Environment Agency. For agglomerations of this scale, the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive, typically require secondary treatment as a minimum standard. Regulatory compliance ensures appropriate treatment for the receiving environment. The plant discharges treated effluent into local watercourses that ultimately drain into the River Thame, a tributary of the River Thames. The Thames basin supports diverse aquatic life and is an important ecological corridor in southern England. The plant's operations contribute to protecting water quality in this sensitive river system.

The treated effluent from THAME THAME OXON STW enters the River Thame, which flows into the River Thames, eventually reaching the North Sea via the Thames Estuary. The Thames basin is a vital freshwater ecosystem supporting species such as Atlantic salmon, brown trout, and European eel. Maintaining high water quality standards is essential for the ecological health of this river system and downstream estuarine habitats.
