West Bergholt STW - Colchester, Essex Wastewater Treatment Plant

West Bergholt STW is a wastewater treatment plant located in West Bergholt, near Colchester, Essex, England. It serves a population of around 4,912 people, making it a small-scale facility within the UK's wastewater infrastructure. The plant is situated in a rural-urban fringe area, contributing to the sanitation needs of the local community. As a UK wastewater treatment plant, West Bergholt STW is subject to the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. For a plant serving fewer than 10,000 people, secondary treatment is typically required unless the receiving water is designated as a sensitive area. The plant's designed capacity is 1.00 (likely in megaliters per day or similar unit), indicating its scale. The treated effluent from West Bergholt STW is discharged into a local watercourse, which eventually drains into the River Colne or its tributaries. The River Colne flows through Colchester and into the Colne Estuary, which is part of the Essex coastline and ultimately reaches the North Sea. The local watershed supports diverse aquatic life and is important for regional biodiversity.

The plant discharges into a tributary of the River Colne, which flows through Colchester and into the Colne Estuary, a coastal inlet of the North Sea. The estuary supports important habitats for migratory birds and fish species, including the European eel. The surrounding area is a mix of agricultural land and urban development, with the water quality of the Colne being managed under the Water Framework Directive.
