Overview
ARV KARSHULT is a wastewater treatment plant in Motala, Östergötlands län, Sweden, serving approximately 34,270 people. It operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
ARV KARSHULT is a wastewater treatment plant located in Karshult, Motala kommun, Östergötlands län, Sweden. It serves a population of approximately 34,270, classifying it as a medium-sized agglomeration under EU regulations. However, as a Swedish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Sweden's environmental standards often mandate advanced treatment in sensitive areas. The plant discharges into the local watershed, which ultimately drains into the Baltic Sea via the Motala Ström river system. This region supports diverse aquatic life and is part of a broader ecosystem that includes coastal and marine environments. Proper treatment is essential to protect water quality in the Baltic Sea, which faces eutrophication challenges.
Environmental context
The plant's treated effluent flows into the Motala Ström river system, which drains into the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it sensitive to nutrient pollution. The watershed supports diverse aquatic habitats and is important for migratory fish species. Effective wastewater treatment helps mitigate eutrophication and protects the ecological balance of the region.
