Overview
Katrineholms Avloppsreningsverk is a municipal wastewater treatment plant serving Katrineholm, Sweden. It operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
Katrineholms Avloppsreningsverk is the municipal wastewater treatment plant for Katrineholm, a city in Södermanland County, Sweden. The plant serves a population of approximately 37,617 people, placing it in the medium agglomeration category under EU classification. As a Swedish facility, the plant 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, and plants serving populations over 15,000 are subject to regular monitoring and reporting requirements. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Nyköpingsån river system. The Baltic Sea is a sensitive marine environment with eutrophication concerns, making nutrient removal an important aspect of wastewater treatment in the region.
Environmental context
The plant discharges into the Nyköpingsån river basin, which flows through Södermanland and empties into the Baltic Sea near Nyköping. The Baltic Sea is a brackish inland sea with limited water exchange, making it highly sensitive to nutrient pollution. Effective wastewater treatment is critical to reducing eutrophication and protecting aquatic ecosystems in this region.
