Bodarnas ARV - Advanced Wastewater Treatment Plant in Djurås, Sweden

Bodarnas ARV is a wastewater treatment plant located in Bodarna, Djurås, within Gagnefs municipality, Dalarna County, Sweden. The plant serves a population of approximately 4,238 residents and has a designed capacity of 6,000 cubic meters per day, with a current discharge volume of 665.29 cubic meters per day. The plant employs advanced treatment processes, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 PE), the directive mandates secondary treatment, but Sweden often requires advanced treatment to protect sensitive inland waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Dalälven River and then into the Baltic Sea. The plant plays a crucial role in maintaining water quality in the region, supporting aquatic life and downstream ecosystems.

Bodarnas ARV discharges into the Dalälven River basin, which flows into the Baltic Sea. The Dalälven is one of Sweden's major rivers, supporting diverse aquatic life and providing habitat for species such as salmon and trout. The advanced treatment ensures minimal nutrient and pollutant loading, protecting the river's ecological health and the sensitive coastal environment of the Baltic Sea.
