VANSBRO ARV Wastewater Treatment Plant, Vansbro, Sweden

VANSBRO ARV is a municipal wastewater treatment plant located in Vansbro, Dalarna County, Sweden. The facility serves a population of about 5,800 people, reflecting a medium-sized agglomeration under Swedish and EU classifications. The plant is situated inland, away from coastal areas, and its operations are integral to local water quality management. 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). With a designed capacity of 7,500 m³/day and an average discharge volume of 913 m³/day, the facility has ample capacity to handle current loads. As an advanced treatment plant, it likely incorporates nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The treated effluent is discharged into a local watercourse that ultimately drains into the Dalälven River basin, which flows into the Baltic Sea. The advanced treatment level helps minimize nutrient loading, reducing the risk of eutrophication in downstream waters. The plant's location in a sparsely populated region underscores its role in preserving the natural environment of Dalarna.

The plant discharges into a local watercourse within the Dalälven River basin, which flows southeast into the Baltic Sea. The Dalälven is one of Sweden's major rivers, supporting diverse aquatic life and providing habitat for species such as Atlantic salmon and sea trout. The advanced treatment ensures that nutrient and pollutant loads are minimized, protecting downstream ecosystems from eutrophication and maintaining water quality in the sensitive Baltic Sea coastal zone.
