Overview
Hagesta reningsverk serves Sollefteå distrikt, Sweden, treating wastewater for approximately 22,624 people. The plant operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
Hagesta reningsverk is a municipal wastewater treatment plant located in Sollefteå distrikt, Västernorrlands län, Sweden. It serves a population of approximately 22,624, classifying it as a medium-sized agglomeration under EU criteria. The plant is situated inland, away from the coast, and its operations are integral to the local water management infrastructure. As a Swedish facility, Hagesta reningsverk is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. Sweden has implemented the directive through national legislation, requiring appropriate treatment levels to protect receiving waters. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating its scale. The treated effluent from Hagesta reningsverk is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Ångerman River system. The Baltic Sea is a sensitive brackish water body with limited water exchange, making nutrient removal important for preventing eutrophication. The plant's treatment processes help reduce the load of organic matter and nutrients entering this ecologically significant sea.
Environmental context
The plant discharges into the Ångerman River basin, which flows into the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with low biodiversity and high sensitivity to nutrient pollution. Effective wastewater treatment at Hagesta reningsverk helps mitigate eutrophication risks in this vulnerable marine environment, supporting aquatic life and regional water quality.
