Overview
Trelleborgs avloppsreningsverk serves approximately 31,500 people in Trelleborg, Sweden. The plant operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
Trelleborgs avloppsreningsverk is the municipal wastewater treatment plant for the city of Trelleborg, located in Skåne County, southern Sweden. The plant serves a population of around 31,500, placing it in the medium agglomeration category under EU classification. As a Swedish facility, the plant is regulated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Sweden has also designated sensitive areas where more stringent treatment is required, and the plant's compliance with these standards ensures environmental protection. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it sensitive to nutrient pollution. The plant's treatment processes help reduce the load of organic matter and nutrients, supporting the ecological health of the coastal environment.
Environmental context
The plant discharges into the local water system that flows to the Baltic Sea, a semi-enclosed sea with high ecological sensitivity due to its brackish nature and limited water exchange. Nutrient inputs from wastewater can contribute to eutrophication, so the plant's treatment performance is critical for protecting marine habitats and supporting biodiversity in the region.
