TP 89 of Heinolan kt is a municipal wastewater treatment plant located in Heinola, Finland, within the Päijät-Häme region. The plant serves a population of 27,000, classifying it as a medium-sized agglomeration under Finnish and EU regulations. As a Finnish wastewater treatment facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Finland's national implementation ensures compliance with stringent effluent standards, particularly in sensitive areas like the nearby Lake Päijänne system. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Finland via the Kymijoki river system. This water body supports diverse aquatic life and is an important migratory corridor for fish species. The plant plays a key role in protecting downstream water quality in the Baltic Sea region.
Environmental context
The plant discharges into the Kymijoki river basin, which flows into the Gulf of Finland, a part of the Baltic Sea. The Baltic Sea is a sensitive brackish water ecosystem with limited water exchange, making it vulnerable to nutrient pollution. The plant's treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in coastal waters.
