Overview
Granskars avloppsreningsverk serves Söderhamn, Sweden, treating wastewater for approximately 11,315 residents. The plant discharges into the Baltic Sea via local waterways.
Granskars avloppsreningsverk is a municipal wastewater treatment plant located in Söderhamn, Gävleborgs län, Sweden. It serves a population of around 11,315 people, classifying it as a medium-sized agglomeration under Swedish and EU regulations. As a Swedish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into sensitive areas like the Baltic Sea. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating it is sized for its service population. The treated effluent is discharged into the Baltic Sea, a brackish inland sea with significant ecological sensitivity. The plant plays a key role in protecting coastal water quality and reducing nutrient loads that contribute to eutrophication in the Baltic region.
Environmental context
The plant's discharge ultimately reaches the Baltic Sea, a semi-enclosed sea with limited water exchange, making it highly susceptible to nutrient pollution. The surrounding watershed includes forested and agricultural areas, and the plant's treatment helps mitigate algal blooms and oxygen depletion in coastal zones. The Baltic Sea supports diverse marine life and is a critical migratory route for fish and birds.
