Overview
TP 525 of Mantsalan kk serves approximately 13,600 people in Mäntsälä, Uusimaa, Finland. The plant is part of Finland's municipal wastewater infrastructure under EU regulations.
TP 525 of Mantsalan kk is a wastewater treatment plant located in Mäntsälä, a town in the Uusimaa region of southern Finland. The plant serves a population of about 13,600 residents, placing it in the medium agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a Finnish facility, it operates within the national framework that implements the EU directive, which mandates secondary treatment for agglomerations of this size, with tertiary treatment required in sensitive areas. Under Finnish and EU regulations, plants serving over 10,000 people must meet secondary treatment standards, and those in sensitive catchments may require nutrient removal. It is expected to comply with national permit conditions set by the Finnish environmental authorities. The treated effluent from TP 525 of Mantsalan kk is discharged into local water bodies that ultimately drain into the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. The plant's operations contribute to protecting downstream aquatic ecosystems, including rivers and coastal areas in the Uusimaa region, by reducing organic load and nutrients.
Environmental context
The plant discharges into the local watershed that flows through the Uusimaa region and eventually reaches the Gulf of Finland, a basin of the Baltic Sea. The Baltic Sea is ecologically sensitive due to its brackish waters, limited circulation, and vulnerability to eutrophication from nutrient inputs. The receiving water bodies support diverse aquatic life and are important for regional biodiversity, including migratory fish species. Effective wastewater treatment at this plant helps mitigate nutrient loading and protects downstream habitats.
