Overview
TP 161 of Joensuun kt serves 80,000 people in Joensuu, Finland, within 50 km of the coast. The plant operates under EU Urban Waste Water Treatment Directive standards.
TP 161 of Joensuun kt is a municipal wastewater treatment plant located in Joensuu, Pohjois-Karjala, Finland. It serves a population of approximately 80,000, classifying it as a large agglomeration under EU regulations. The plant is situated near the city center, with its address in the Linnunlahti district. As a Finnish plant serving over 10,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For large agglomerations like this, the directive may also mandate more advanced treatment if the receiving waters are sensitive. The plant's designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating a substantial infrastructure. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Finland via the Vuoksi River system. This water body is part of the Baltic Sea, a brackish sea with significant ecological sensitivity. The plant plays a key role in protecting downstream aquatic life and water quality in the region.
Environmental context
The plant discharges into the Vuoksi River basin, which flows through the Saimaa lake system and eventually into the Gulf of Finland, a part of the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea with limited water exchange, making it vulnerable to nutrient pollution. The plant's operations help control nutrient loads, supporting the ecological health of downstream lakes and coastal waters.
