Gloucester Netheridge STW Wastewater Treatment Plant, Gloucester, England

Gloucester Netheridge STW is a major wastewater treatment facility serving the city of Gloucester in Gloucestershire, England. With a population equivalent of around 191,000, it is classified as a large agglomeration under UK wastewater regulations. The plant's designed capacity is 1.00 (likely in megaliters per day or similar unit), indicating a substantial treatment capability. As a UK facility, it operates under the Urban Waste Water Treatment Regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, secondary treatment is mandatory, and tertiary treatment may be required if the receiving waters are sensitive. The treated effluent is discharged into the River Severn catchment, which flows into the Severn Estuary and then the Bristol Channel. The River Severn supports diverse aquatic life and is an important ecological corridor. The plant's discharge must comply with strict environmental quality standards to protect this sensitive downstream environment.

The plant discharges into the River Severn catchment, which flows through Gloucestershire to the Severn Estuary and the Bristol Channel. This estuary is a major ecological feature supporting migratory fish, wading birds, and diverse marine life. The receiving waters are subject to nutrient and pollution controls under UK and EU frameworks to maintain water quality.
