Stromsunds avloppsreningsverk is a municipal wastewater treatment facility located in Strömsund, Jämtland County, Sweden. The plant serves a population of approximately 5,300, classifying it as a small to medium agglomeration under Swedish and EU regulations. It operates with advanced treatment technology, ensuring high-quality effluent before discharge. The plant has a designed capacity of 7,000 cubic meters per day and currently treats an average daily volume of about 835 cubic meters, indicating ample reserve capacity. As an advanced treatment facility, it likely incorporates nutrient removal processes to meet stringent Swedish environmental standards, which align with the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The treated effluent is discharged into the local water system, which ultimately drains into the Baltic Sea via the Ångermanälven river basin. This discharge supports the ecological health of downstream waters, including lakes and rivers that are important for biodiversity and recreation. The plant's advanced treatment helps minimize nutrient loading, protecting the Baltic Sea from eutrophication.
Environmental context
The plant discharges into the local watershed, which is part of the Ångermanälven river basin. This river flows into the Bothnian Sea, a sub-basin of the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea sensitive to nutrient pollution, where advanced treatment helps reduce algal blooms and oxygen depletion. The surrounding region features boreal forests and numerous lakes, supporting diverse aquatic life and migratory fish species.
