MOSSLEY STW - Tameside, Greater Manchester Wastewater Treatment Plant

MOSSLEY STW is a wastewater treatment plant located in Tameside, Greater Manchester, England. The facility serves a population of approximately 12,648 people, placing it in the medium agglomeration category under UK and EU regulatory standards. As a plant of this scale in the United Kingdom, MOSSLEY STW is expected to comply with the Urban Waste Water Treatment Directive (UWWTD) transposed into UK law, which mandates at least secondary treatment for inland discharges from agglomerations of this size. The plant's treatment processes are designed to meet these standards, ensuring effective removal of organic matter and suspended solids before discharge. The treated effluent from MOSSLEY STW is discharged into local watercourses that ultimately drain into the River Tame and then the River Mersey, which flows into the Irish Sea. This catchment supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting water quality in the Mersey Basin.

MOSSLEY STW discharges into local watercourses that feed the River Tame, a tributary of the River Mersey. The Mersey flows into the Irish Sea via the Mersey Estuary, which is an ecologically important area supporting migratory fish, wading birds, and diverse estuarine habitats. The plant's operations help maintain water quality in this sensitive downstream environment.
