AYLESBURY RABANS LANE AYLESBU STW Wastewater Treatment Plant, Fairford Leys, England

AYLESBURY RABANS LANE AYLESBU STW is a wastewater treatment plant located in Fairford Leys, Buckinghamshire, England. It serves a population of around 99,300, classifying it as a large agglomeration under UK and EU regulatory frameworks. The plant is situated inland, over 50 km from the coast, and discharges into local watercourses that eventually drain into the River Thames and the North Sea. As a large agglomeration, the plant is required to meet stringent treatment standards under the Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum and tertiary treatment if discharging into sensitive areas. The UK's Environment Agency oversees compliance through permitting and monitoring. The regulatory framework ensures that plants of this scale operate with appropriate technology to protect water quality. The plant's treated effluent likely enters the River Thame or a tributary, which flows into the River Thames and ultimately the North Sea. This catchment supports diverse aquatic life and is important for water supply and recreation. The plant plays a key role in maintaining the ecological health of the Thames Basin by reducing nutrient and pollutant loads.

The plant discharges into local watercourses within the Thames Basin, which drains into the River Thames and then the North Sea. The Thames estuary is an ecologically sensitive area supporting diverse fish, bird, and invertebrate populations. Nutrient management is critical to prevent eutrophication in downstream waters, including the Thames and its tributaries.
