Overview
GONAS ARV is a municipal wastewater treatment plant serving Gonäs, Sweden, with a population equivalent of 36,186. It operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
GONAS ARV is a municipal wastewater treatment plant located in Gonäs, within Ludvika kommun, Dalarnas län, Sweden. The plant serves a population equivalent of 36,186, classifying it as a medium-sized agglomeration under EU regulations. Its location near the historic Gonäs hytta site places it within an area of mixed industrial and residential character. As a Swedish plant, GONAS ARV operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. Sweden's implementation requires advanced treatment in sensitive areas, and plants serving over 10,000 people must meet strict nutrient removal standards where applicable. The plant's treatment processes and capacity are designed to comply with these national and EU requirements. The treated effluent from GONAS ARV is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Dalälven river system. This river basin supports diverse aquatic life and is an important ecological corridor in central Sweden. The plant's operations contribute to protecting downstream water quality in the Baltic Sea, a semi-enclosed sea sensitive to nutrient pollution.
Environmental context
GONAS ARV discharges into the Dalälven river basin, which flows into the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it highly sensitive to nutrient inputs. The plant's location in the Dalarna region places it within a watershed that supports diverse aquatic habitats and migratory fish species. Effective wastewater treatment is crucial for maintaining the ecological balance of this downstream environment.
