Overview
ARV Slottshagen is a municipal wastewater treatment plant serving Norrköping, Sweden, with a population equivalent of 190,861. It operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
ARV Slottshagen is a major wastewater treatment facility located in Norrköping, Östergötlands län, Sweden. Serving a population equivalent of 190,861, it is classified as a large agglomeration under EU regulations. The plant is situated in the coastal region of southeastern Sweden, near the Bråviken bay of the Baltic Sea. As a large agglomeration, the plant is required to meet stringent treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment as a minimum, with tertiary treatment required for discharges into sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a substantial infrastructure to handle the region's wastewater. The treated effluent from ARV Slottshagen is discharged into the Baltic Sea via the Bråviken bay. The Baltic Sea is a brackish inland sea with limited water exchange, making it sensitive to nutrient pollution. The plant's operations are critical for protecting the local marine environment and supporting the ecological health of the coastal waters, which are important for biodiversity and recreational activities.
Environmental context
ARV Slottshagen discharges treated wastewater into the Bråviken bay, an inlet of the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with a fragile ecosystem, prone to eutrophication from nutrient inputs. The plant's location within 50 km of the coast underscores its role in managing nutrient loads to this sensitive marine environment, which supports diverse aquatic life and is an important migratory corridor for fish and birds.
