SOHAM STW - East Cambridgeshire Wastewater Treatment Plant

SOHAM STW is a wastewater treatment plant located in The Cotes, Soham, East Cambridgeshire, Cambridgeshire, England. It serves a population of around 14,146, classifying it as a medium-sized agglomeration under UK and EU classifications. The facility is part of the region's municipal wastewater infrastructure, managed by the local water authority. As a plant serving over 10,000 people, SOHAM STW is required to meet secondary treatment standards under the Urban Waste Water Treatment Directive (UWWTD), transposed into UK law. The treatment process typically involves biological treatment to reduce organic matter and suspended solids. The plant is designed to handle the wastewater load from its catchment area. The treated effluent from SOHAM STW is discharged into local watercourses that drain into the River Great Ouse, which flows through the Fens and ultimately into The Wash, a large estuary on the North Sea. This discharge contributes to the water quality of the river system, which supports diverse aquatic life and is important for agriculture and recreation in the region.

SOHAM STW discharges into local watercourses that are part of the River Great Ouse catchment. The River Great Ouse flows through the Fens, a low-lying agricultural region, and enters The Wash, an ecologically significant estuary on the North Sea. The Wash supports important bird populations and marine habitats, making nutrient management and effluent quality critical for downstream ecosystem health.
