Long Stratton STW - Wastewater Treatment Plant in South Norfolk, England

Long Stratton STW is a wastewater treatment facility located in South Norfolk, Norfolk, England. It serves a population equivalent of 5,530, classifying it as a small agglomeration under UK and EU regulatory standards. The plant is situated inland, approximately 50 km from the coast, and its operations are part of the region's municipal wastewater infrastructure. As a small-scale treatment plant in the United Kingdom, Long Stratton STW is subject to the Urban Waste Water Treatment Regulations (transposing the EU Urban Waste Water Treatment Directive). These regulations require secondary treatment for discharges to freshwater and estuaries for agglomerations of this size, unless a higher level is needed for sensitive areas. The plant's designed capacity is 1.00 (likely in megaliters per day or similar unit), indicating a modest scale. The treated effluent from Long Stratton STW is discharged into local watercourses that ultimately drain into the North Sea via the Yare River system. The Norfolk Broads, a network of rivers and lakes, are ecologically sensitive and support diverse aquatic life, including rare species. The plant's discharge must meet quality standards to protect these downstream environments.

The plant discharges into local tributaries of the River Yare, which flows through the Norfolk Broads and into the North Sea at Great Yarmouth. The Broads are a wetland ecosystem of international importance, supporting diverse birdlife, fish, and aquatic plants. The plant's effluent quality is critical to maintaining the ecological balance of this sensitive downstream environment.
