Overview
TP 373 of Kemijarven kt is a wastewater treatment plant serving approximately 7,900 people in Kemijärvi, Lappi, Finland. It operates under Finnish environmental regulations within the EU Urban Waste Water Treatment Directive framework.
TP 373 of Kemijarven kt is a municipal wastewater treatment plant located in Sipovaara, Kemijärvi, in the Lappi region of Finland. The plant serves a population of approximately 7,900, placing it in the category of small to medium agglomerations under EU classification. As a Finnish plant, TP 373 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater in areas with a population equivalent above 2,000. Finland's cold climate and sensitive northern water bodies often necessitate advanced treatment to protect receiving waters. The plant's treated effluent is discharged into the local watershed, which drains into the Kemijoki river system. The Kemijoki is Finland's longest river, flowing into the Gulf of Bothnia in the Baltic Sea. This river system supports diverse aquatic life and is important for regional ecology and recreation.
Environmental context
The plant discharges into the Kemijoki river basin, which flows into the Gulf of Bothnia, part of the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The Kemijoki watershed supports salmon and other migratory fish species, and the region's cold climate means biological treatment processes can be less efficient, requiring careful management to prevent eutrophication downstream.
Frequently asked questions
TP 373 of Kemijarven kt is located in Sipovaara, Kemijärvi, in the Lappi region of Finland.
The plant serves approximately 7,900 people, classifying it as a small to medium agglomeration under EU standards.
The plant discharges treated effluent into the local watershed, which flows into the Kemijoki river system and eventually reaches the Gulf of Bothnia in the Baltic Sea.
As a Finnish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 population equivalent, with additional requirements for sensitive areas.
For plants of this scale in Finland, secondary biological treatment is standard, often with nutrient removal to protect sensitive northern water bodies from eutrophication.
