BARSTON STW - Solihull, England Wastewater Treatment Plant

BARSTON STW is a wastewater treatment plant located in Solihull, West Midlands, England. It serves a population of around 65,518, classifying it as a medium-sized agglomeration under UK and EU wastewater directives. The plant is situated in an inland area, away from the coast, and its operations are integral to the region's sanitation infrastructure. As a UK wastewater facility, BARSTON STW is regulated under the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. For a plant serving over 15,000 people, secondary treatment is required, and if the receiving water is sensitive, tertiary treatment may be mandated. The plant's treatment processes are designed to meet these standards, protecting local water quality. The treated effluent from BARSTON STW is discharged into local watercourses that ultimately drain into the River Blythe, a tributary of the River Tame, which flows into the River Trent and then to the Humber Estuary and the North Sea. This downstream chain supports diverse aquatic life and is important for regional biodiversity.

BARSTON STW discharges into the River Blythe catchment, which flows into the River Tame, then the River Trent, and finally the Humber Estuary and North Sea. The River Blythe is a groundwater-fed river supporting diverse aquatic habitats, including populations of brown trout and other sensitive species. The plant's discharge must comply with stringent quality standards to protect this ecologically important watercourse.
