Stromstads avloppsreningsverk - Strömstad Wastewater Treatment Plant

Stromstads avloppsreningsverk is a municipal wastewater treatment plant located in Strömstad, a coastal town in Västra Götaland County, Sweden. The plant serves a population of around 11,327 residents, classifying it as a medium-sized agglomeration under EU standards. Its location near the Swedish west coast places it in a sensitive marine environment. As a Swedish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. For plants in sensitive coastal areas, the directive may require more advanced treatment to protect marine ecosystems. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the local population's wastewater flow. The treated effluent from Stromstads avloppsreningsverk is discharged into the Skagerrak, a marginal sea of the North Sea, which ultimately connects to the Atlantic Ocean. This coastal discharge requires careful management to prevent nutrient enrichment and protect the diverse marine life, including fish stocks and seabird populations, that depend on the area's water quality.

The plant discharges into the Skagerrak, a sea that connects the North Sea and the Atlantic Ocean. This coastal environment supports diverse marine ecosystems, including important fisheries and migratory bird routes. Nutrient inputs from wastewater must be carefully controlled to avoid eutrophication, which can harm water quality and marine biodiversity in this sensitive region.
