TP 199 of Jamsan kt is a municipal wastewater treatment plant located in Jämsä, within the Keski-Suomi region of Finland. The plant serves a population of approximately 15,200, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). Its location near the Kaipola area places it within a region characterized by lakes and forests, typical of central Finland. As a Finnish plant serving over 10,000 people, it is subject to the EU Urban Waste Water Treatment Directive, which requires secondary treatment as a minimum standard. For agglomerations of this scale, the directive also mandates appropriate treatment to prevent eutrophication in sensitive areas. 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 treated effluent from TP 199 of Jamsan kt 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 Päijänne basin supports diverse aquatic life and provides drinking water for the Helsinki metropolitan area. Proper treatment at this plant helps protect water quality in this important water body.
Environmental context
The plant discharges into the local watershed that feeds into Lake Päijänne, a major lake in central Finland. Lake Päijänne is part of the Kymijoki river basin, which drains into the Gulf of Finland in the Baltic Sea. The lake supports diverse aquatic ecosystems, including fish species such as pike, perch, and vendace, and is an important migratory corridor for birds. Protecting water quality in this basin is critical for both ecological health and downstream water supply.
