STORSATERNS ARV Wastewater Treatment Plant, Sågliden, Sweden

STORSATERNS ARV is a wastewater treatment plant located in Sågliden, within Älvdalens kommun, Dalarnas län, Sweden. It serves a small population of 602 residents, reflecting its role in a rural or semi-rural community. The plant is situated in a sparsely populated area near the Norwegian border, characterized by forested landscapes and cold climate. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 4,100 m³/day, with an actual discharge volume of 94.5 m³/day, indicating significant reserve capacity. As a Swedish facility, it operates under national regulations that implement EU directives, with oversight likely from the county administrative board or the Swedish Environmental Protection Agency. The treated effluent is discharged into local watercourses that ultimately drain into the Baltic Sea via the Dalälven river system. The plant's advanced treatment helps protect sensitive downstream ecosystems, including lakes and rivers that support diverse aquatic life and serve as important habitats for fish and migratory birds.

The plant discharges into local streams that flow into the Dalälven river system, which drains into the Baltic Sea. The Dalälven is one of Sweden's major rivers, supporting diverse aquatic ecosystems including salmon and trout populations. The surrounding area includes boreal forests and wetlands that provide important habitat for wildlife. Advanced treatment at this plant helps minimize nutrient loading and protect water quality in this sensitive northern watershed.
