Overview
TYLDESLEY STW is a wastewater treatment plant serving approximately 31,985 people in Wigan, Greater Manchester, England. It operates under the UK's regulatory framework for wastewater treatment.
TYLDESLEY STW is a wastewater treatment plant located in Wigan, Greater Manchester, England, serving a population of approximately 31,985. The plant is situated inland, away from coastal areas, and plays a key role in managing municipal wastewater for the local community. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment for populations over 2,000. The plant discharges treated effluent into local watercourses that ultimately drain into the River Mersey catchment, which flows into the Irish Sea. This makes the plant's performance important for protecting downstream water quality and aquatic ecosystems in the Mersey Basin.
Environmental context
The plant's treated effluent enters the River Mersey catchment, which flows through Greater Manchester and into the Mersey Estuary before reaching the Irish Sea. The Mersey Basin supports diverse aquatic life and is a key migratory corridor for fish species. Effective treatment at TYLDESLEY STW helps reduce nutrient and pollutant loads, protecting both freshwater and marine environments.
