NUNEATON STW - Wastewater Treatment Plant in North Warwickshire, England

NUNEATON STW is a municipal wastewater treatment plant located in North Warwickshire, Warwickshire, England. The plant serves a population of approximately 97,328, placing it in the category of a large agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD), which the UK has retained post-Brexit. The facility is situated near the town of Atherstone and is part of the region's wastewater infrastructure. As a large agglomeration, the plant is expected to provide at least secondary treatment, with tertiary treatment required if discharging into sensitive areas. The UK's Environment Agency regulates such plants under the Environmental Permitting Regulations, ensuring compliance with discharge standards. Regulatory requirements mandate robust treatment for this population size. The plant discharges treated effluent into local watercourses that ultimately drain into the River Anker, a tributary of the River Tame, which flows into the River Trent and then into the Humber Estuary and the North Sea. This downstream chain supports diverse aquatic life and is important for regional water quality management.

The plant's treated effluent enters local watercourses that feed into the River Anker, a tributary of the River Tame. The Tame joins the River Trent, which flows into the Humber Estuary and ultimately the North Sea. This watershed supports diverse aquatic ecosystems, including fish populations and migratory species. The area is ecologically sensitive, with the Trent Valley providing important habitats for birds and aquatic life.
