BOWERHILL STW - Berryfield, Wiltshire Wastewater Treatment Plant

BOWERHILL STW is a wastewater treatment plant located in Berryfield, Wiltshire, England, serving a population of around 6,111. It is situated inland, more than 50 km from the coast, and is part of the UK's wastewater infrastructure managed under the Water Industry Act 1991. As a plant serving a medium-sized agglomeration, BOWERHILL STW is expected to meet secondary treatment standards under the Urban Waste Water Treatment Directive (91/271/EEC), which is implemented in the UK through national regulations. It operates within the regulatory framework that ensures compliance with environmental standards. The treated effluent from BOWERHILL STW is discharged into the local water environment, likely into a tributary of the River Avon, which flows through Wiltshire and eventually into the Bristol Channel. This river system supports diverse aquatic life and is important for regional biodiversity and water quality management.

BOWERHILL STW discharges into the River Avon catchment, which drains into the Bristol Channel. The River Avon supports a variety of fish species, including salmon and trout, and is an important ecological corridor. The plant's location inland, away from sensitive coastal areas, reduces direct marine impact, but its discharge must meet strict quality standards to protect the river's ecosystem.
