Upton on Severn STW - Secondary Wastewater Treatment Plant in Malvern Hills, England

Upton on Severn STW is a wastewater treatment plant located near the town of Upton-upon-Severn in Worcestershire, England. It serves a population of approximately 2,854 residents in the Malvern Hills area, operating as a secondary treatment facility under the UK's water quality regulations. The plant has a designed capacity of 3,500 cubic meters per day and currently discharges a daily volume of 635.4 cubic meters, indicating it operates well below its capacity. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids, meeting the standards required by the Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Treated effluent from the plant is discharged into the River Severn catchment, which flows into the Severn Estuary and eventually the Bristol Channel. The River Severn is the longest river in the UK and supports diverse aquatic life, including salmon and eel populations. The plant plays a key role in protecting this important waterway from pollution.

The plant discharges into the River Severn catchment, which drains into the Severn Estuary and the Bristol Channel. The River Severn is a major ecological corridor supporting migratory fish such as Atlantic salmon and European eel. The estuary is a vital habitat for wading birds and waterfowl, making the plant's secondary treatment essential for maintaining water quality in this sensitive downstream environment.
