FELTWELL STW - Secondary Wastewater Treatment Plant in King's Lynn and West Norfolk, England

FELTWELL STW is a wastewater treatment plant located in Feltwell, near King's Lynn and West Norfolk in Norfolk, England. The facility serves a population of approximately 2,064 and operates under the regulatory framework of the United Kingdom, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC) through national legislation. As a secondary treatment plant, it meets the standard required for inland freshwater discharges under the directive. The plant has a designed capacity of 2,064 population equivalent and treats an average daily flow of 459.52 m³. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with UK environmental standards. The facility is operated as part of the regional wastewater infrastructure managed by the local water authority. The treated effluent is discharged into local watercourses that drain into the River Great Ouse system, eventually reaching The Wash, a large estuary and embayment of the North Sea. This area supports diverse aquatic life and is an important habitat for migratory birds. The plant's discharge contributes to the overall water quality management of the catchment, protecting downstream ecosystems and recreational uses.

The plant discharges into the River Great Ouse catchment, which flows into The Wash, a major estuary on the east coast of England. The Wash is an ecologically sensitive area supporting diverse bird populations, salt marshes, and marine life. The secondary treatment provided by FELTWELL STW helps reduce nutrient loads and organic pollution, mitigating eutrophication risks in the downstream estuary.
