TP 1900011362 of Joutsan kk is a municipal wastewater treatment facility located in Joutsa, within the Keski-Suomi region of Finland. The plant serves a population of approximately 3,700, placing it in the small-to-medium agglomeration category under Finnish and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The reported discharge volume is 606.42 units, indicating the scale of treated effluent released. The treated effluent is discharged into the local watershed, which ultimately drains into the Päijänne lake system, one of Finland's largest and most ecologically significant lakes. The plant's advanced treatment helps safeguard water quality in this region, supporting aquatic life and downstream uses such as recreation and drinking water supply.
Environmental context
The plant discharges into the local watershed that feeds into Lake Päijänne, a major lake in southern Finland. Lake Päijänne is part of the Kymijoki river basin, which flows into the Gulf of Finland. The lake supports diverse aquatic ecosystems and is an important source of drinking water for the Helsinki region. Advanced treatment at this plant helps control nutrient loading, reducing the risk of eutrophication in the lake and its downstream environments.
