Overview
TP 459 of Loviisan kt serves about 15,000 people in Loviisa, Uusimaa, Finland. The plant operates under Finland's national implementation of the EU Urban Waste Water Treatment Directive.
TP 459 of Loviisan kt is a wastewater treatment plant located in Hattom, Loviisa, in the Uusimaa region of Finland. It serves a population of approximately 15,000, placing it in the medium agglomeration category under EU classification. The plant is situated near the coast of the Gulf of Finland. As a Finnish facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries, and more advanced treatment for sensitive areas. For a population of 15,000, the directive mandates appropriate treatment to protect the receiving environment. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the local wastewater load. The plant discharges treated wastewater into the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is a brackish inland sea with limited water exchange, making it sensitive to nutrient pollution. Effective treatment at plants like TP 459 helps reduce eutrophication risks and supports the ecological health of the coastal waters and marine environment.
Environmental context
The plant's treated effluent enters the Gulf of Finland, which connects to the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it highly sensitive to nutrient inputs. Eutrophication from nitrogen and phosphorus is a major concern, and treatment plants in the region must meet stringent discharge standards to protect marine ecosystems and support biodiversity.
