ROYTON STW - Wastewater Treatment Plant in Royton, Greater Manchester

ROYTON STW is a wastewater treatment plant located in Royton, a town in the Metropolitan Borough of Oldham, Greater Manchester, England. The facility serves a population of around 30,495, classifying it as a medium-sized agglomeration under UK and EU standards. It is situated in an urban area within the River Irwell catchment. As a UK wastewater treatment plant, ROYTON STW operates under the Water Industry Act 1991 and is regulated by the Environment Agency. For a population of this scale, the Urban Waste Water Treatment Directive (transposed into UK law) typically requires secondary treatment or more stringent treatment if the receiving water is designated as sensitive. It is expected to meet the required standards for its discharge. The plant discharges treated effluent into the local watercourse, which ultimately drains into the River Irwell and then to the Manchester Ship Canal and the Irish Sea. The River Irwell supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting water quality in this urbanized catchment.

ROYTON STW discharges into the River Irwell catchment, which flows through Greater Manchester and joins the Manchester Ship Canal before reaching the Irish Sea. The River Irwell is a heavily modified waterbody that supports fish populations and other aquatic species. The plant's treatment helps reduce nutrient and pollutant loads, contributing to the ecological health of the downstream environment.
