Overview
Brunna avloppsreningsverk serves Hedemora, Sweden, treating wastewater for approximately 16,136 people. The plant operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
Brunna avloppsreningsverk is a municipal wastewater treatment plant located in the Brunna villaområde area of Hedemora, in Dalarnas län, Sweden. It serves a population of around 16,136 people, classifying it as a medium-sized agglomeration under EU classification. As a Swedish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Sweden's national regulations enforce strict effluent standards to protect sensitive water bodies, and plants serving over 10,000 population equivalents are typically equipped with nutrient removal to reduce eutrophication in the Baltic Sea region. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Dalälven river system and then into the Baltic Sea. This region is ecologically sensitive due to the Baltic Sea's vulnerability to nutrient pollution, making effective wastewater treatment crucial for protecting marine ecosystems and supporting biodiversity.
Environmental context
The plant discharges into the Dalälven river basin, which flows into the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it highly sensitive to nutrient inputs from wastewater. Effective treatment at plants like Brunna avloppsreningsverk helps reduce eutrophication, which can cause algal blooms and oxygen depletion, threatening fish populations and aquatic habitats.
Frequently asked questions
Brunna avloppsreningsverk is located in the Brunna villaområde area of Hedemora, in Dalarnas län, Sweden.
The plant serves approximately 16,136 people, classifying it as a medium-sized agglomeration under EU classification.
The treated effluent is discharged into the local watershed, which flows into the Dalälven river system and ultimately into the Baltic Sea.
As a Swedish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Swedish regulations also mandate nutrient removal to protect the sensitive Baltic Sea.
Plants of this scale in Sweden typically employ secondary treatment with nutrient removal (nitrogen and phosphorus) to meet stringent effluent standards aimed at reducing eutrophication in the Baltic Sea.
