BRACKLEY STW Wastewater Treatment Plant, Turweston, Buckinghamshire

BRACKLEY STW is a wastewater treatment plant located on Mill Lane in Turweston, Buckinghamshire, England. Serving a population of around 28,644, it is part of the UK's municipal wastewater infrastructure managed under the Water Industry Act 1991 and the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. As a medium-sized agglomeration, the plant is expected to provide secondary treatment as a minimum, with tertiary treatment required if discharging into sensitive areas. The plant operates under the regulatory framework set by the Environment Agency, which issues discharge permits and monitors compliance. The treated effluent is discharged into local watercourses that eventually drain into the River Great Ouse basin, flowing towards The Wash and the North Sea. This catchment supports diverse aquatic life and is important for regional water quality management.

The plant discharges into the River Great Ouse catchment, which flows through Buckinghamshire and into The Wash, a large estuary and important ecological area on the North Sea coast. The downstream environment supports diverse aquatic species and migratory birds, making water quality management critical for maintaining ecosystem health.
