TP 49 of Forssan kt is a wastewater treatment plant located in Forssa, within the Kanta-Häme region of Finland. The plant serves a population of approximately 92,600, classifying it as a large agglomeration under EU regulations. It is situated inland, away from coastal areas, and its operations are part of Finland's comprehensive wastewater management infrastructure. As a facility serving over 10,000 people, TP 49 of Forssan kt is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. For larger agglomerations, such as this one, the directive may also mandate more advanced treatment if the receiving waters are sensitive to eutrophication. The plant's treatment processes and capacity are designed to meet these regulatory requirements, ensuring compliance with Finnish environmental standards. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Baltic Sea, a sensitive marine environment. The plant plays a crucial role in protecting the Kokemäenjoki river basin and the Archipelago Sea from nutrient pollution. By reducing organic matter and nutrients, the facility helps maintain water quality and supports aquatic ecosystems in the region.
Environmental context
The plant discharges into the Kokemäenjoki river system, which flows into the Bothnian Sea, part of the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it highly sensitive to nutrient loading. The plant's operations help mitigate eutrophication risks by reducing phosphorus and nitrogen inputs, supporting the ecological health of downstream coastal and marine habitats.
Frequently asked questions
TP 49 of Forssan kt is located in Forssa, in the Kanta-Häme region of Finland. The address is 2, Munkkiniementie, Kaikula, Forssa.
The plant serves approximately 92,600 people, classifying it as a large agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent is discharged into local water bodies that are part of the Kokemäenjoki river system, which eventually flows into the Bothnian Sea and the Baltic Sea.
As a Finnish plant serving over 10,000 people, TP 49 of Forssan kt operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment and potentially advanced treatment for sensitive areas.
Under the EU UWWTD, plants of this scale typically require secondary treatment (biological treatment) and may need tertiary treatment if discharging into sensitive waters like the Baltic Sea. Finnish regulations often implement nutrient removal to reduce eutrophication.
