TP 611 of Pielaveden kk is a municipal wastewater treatment facility located in Pielavesi, within the Pohjois-Savo region of Finland. The plant serves a population of around 3,100 residents, making it a small-scale facility under Finnish and EU classifications. Its location in the inland region of eastern Finland places it within the catchment area of the Kymijoki basin, which drains into the Gulf of Finland. 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, targeting phosphorus and nitrogen, which is crucial for protecting sensitive inland waters and the Baltic Sea from eutrophication. The plant's discharge volume is reported at 508.08 cubic meters per day, indicating a consistent operational scale. Environmentally, the plant plays a key role in safeguarding local water quality. Its treated effluent is discharged into nearby watercourses that eventually flow into the Kymijoki River system and then to the Gulf of Finland. This region is ecologically sensitive, supporting diverse aquatic life and serving as a habitat for migratory fish species. The advanced treatment helps minimize nutrient loading, reducing the risk of algal blooms and maintaining the ecological balance of downstream lakes and rivers.
Environmental context
The plant discharges into the local watershed within the Kymijoki basin, which flows through eastern Finland into the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is highly sensitive to nutrient pollution, and advanced treatment at this plant helps reduce phosphorus and nitrogen loads, mitigating eutrophication. The surrounding region includes numerous lakes and rivers that support diverse aquatic ecosystems, including fish populations important for local fisheries.
