Polesworth STW - Wastewater Treatment Plant in North Warwickshire, England

Polesworth STW is a wastewater treatment plant located in North Warwickshire, Warwickshire, England, serving a population of around 9,073. The plant is part of the UK's wastewater infrastructure, which is regulated under the Urban Waste Water Treatment Directive (UWWTD) transposed into national law. As a facility serving a medium-sized agglomeration, it is expected to provide at least secondary treatment to meet environmental standards. The plant's discharge ultimately enters the local river system, contributing to the health of the downstream environment. The UK's Environment Agency oversees permitting and compliance to ensure treated effluent meets quality standards before release. The receiving water body is part of the Humber River Basin, which drains into the North Sea, supporting diverse aquatic life and ecosystems.

Polesworth STW discharges treated effluent into local watercourses that flow into the River Anker, a tributary of the River Tame, which joins the River Trent. The Trent then flows into the Humber Estuary and the North Sea. This watershed supports a range of freshwater and estuarine habitats, including fish populations and migratory birds. The plant's treatment performance is critical to maintaining water quality in these sensitive environments.
