Overview
Sandefjord renseanlegg serves approximately 87,500 people in Sandefjord, Norway. The plant is located within 50 km of the coast and discharges into the Skagerrak via local waterways.
Sandefjord renseanlegg is a municipal wastewater treatment plant serving the city of Sandefjord in Vestfold, Norway. With a population equivalent of roughly 87,500, it is classified as a large agglomeration under Norwegian regulations, which align with the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant's designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating it is sized to handle the region's wastewater load. As a Norwegian facility, Sandefjord renseanlegg operates under national regulations that implement the EU UWWTD. For agglomerations larger than 10,000 population equivalent, secondary treatment is required, and more stringent tertiary treatment may be mandated in sensitive areas. Given its scale and coastal proximity, it likely meets or exceeds secondary treatment standards to protect the marine environment. The treated effluent from Sandefjord renseanlegg is discharged into local watercourses that flow into the Skagerrak, a strait connecting the North Sea to the Baltic Sea. This coastal discharge point is ecologically sensitive, supporting diverse marine life including fish, crustaceans, and seabirds. The plant plays a key role in preventing nutrient pollution and safeguarding water quality in the Skagerrak and the broader North Sea ecosystem.
Environmental context
Sandefjord renseanlegg discharges treated wastewater into local streams that drain into the Skagerrak, a strait between Norway, Sweden, and Denmark. The Skagerrak is a productive marine area supporting fisheries and biodiversity, including cod, herring, and harbor porpoises. Nutrient loading from wastewater can contribute to eutrophication, so the plant's treatment performance is critical for maintaining the ecological health of this coastal region.
