Overview
TUVAN S AVLOPPSREN VERK is a wastewater treatment plant serving Bergsbyn, Sweden, with a population equivalent of 48,812. It operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
TUVAN S AVLOPPSREN VERK is a wastewater treatment plant located in Bergsbyn, within the Skellefteå municipality of Västerbottens län, Sweden. The plant serves a population equivalent of 48,812, classifying it as a medium agglomeration under EU regulations. 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 has implemented the directive through national legislation enforced by county administrative boards. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating its scale. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Bothnia, a brackish sea arm of the Baltic Sea. The receiving waters support diverse aquatic life and are important for regional fisheries and migratory bird populations. The plant plays a key role in protecting this sensitive coastal environment from nutrient pollution.
Environmental context
The plant discharges into the Skellefte River system, which flows into the Gulf of Bothnia. This coastal area is ecologically sensitive, supporting diverse aquatic life including salmonids and migratory birds. The Baltic Sea is particularly vulnerable to eutrophication from nutrient inputs, making effective wastewater treatment critical for downstream water quality.

As a Swedish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 population equivalent. Sweden enforces this through national legislation and county administrative boards.
Under the EU Urban Waste Water Treatment Directive, plants serving over 10,000 population equivalent in sensitive areas require tertiary treatment (nutrient removal). For less sensitive areas, secondary treatment is standard. Swedish plants often include phosphorus removal to protect the Baltic Sea.
