Overview
TP 529 of Mantyharjun asseutu serves Mäntyharju, Finland, treating wastewater for approximately 6,200 residents. The plant operates under Finland's national implementation of the EU Urban Waste Water Treatment Directive.
TP 529 of Mantyharjun asseutu is a municipal wastewater treatment plant located in Mäntyharju, in the Etelä-Savo region of Finland. The facility serves a population of approximately 6,200 people, placing it in the small-to-medium agglomeration category under EU classification. As a Finnish plant, it operates under the national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum, with more stringent requirements if the discharge enters a sensitive area. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating it is sized appropriately for its service population. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Kymi River basin or other regional watercourses. The Baltic Sea is a brackish, ecologically sensitive water body that faces challenges from nutrient pollution. Proper treatment at plants like this helps reduce the load of nitrogen and phosphorus, supporting the health of downstream aquatic ecosystems and contributing to regional efforts to combat eutrophication.
Environmental context
The plant discharges into the local watershed within the Kymi River basin, which flows into the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea with limited water exchange, making it highly sensitive to nutrient inputs. Effective wastewater treatment at this plant helps reduce the risk of eutrophication in downstream lakes and coastal waters, supporting biodiversity and water quality in the region.
