TP 919 of Vammalan kt is a municipal wastewater treatment plant located in Sastamala, within the Pirkanmaa region of Finland. The plant serves a population of around 25,000, classifying it as a medium-sized agglomeration under EU standards. It is situated inland, away from coastal areas, and its operations are part of Finland's comprehensive wastewater management infrastructure. As a Finnish plant serving over 10,000 people, TP 919 of Vammalan kt is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For agglomerations of this size, the directive also mandates more advanced treatment if the receiving waters are sensitive to eutrophication. Finland's national regulations align with these EU standards, ensuring that the plant meets appropriate treatment levels to protect water quality. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Gulf of Bothnia via the Kokemäenjoki river system. This river basin supports diverse aquatic life and is important for regional biodiversity. The plant's operations help maintain the ecological health of downstream waters, including lakes and rivers that are used for recreation and fishing.
Environmental context
The plant's treated effluent flows into the Kokemäenjoki river basin, which drains into the Gulf of Bothnia, part of the Baltic Sea. This watershed supports a variety of fish species and aquatic plants, and is an important migratory corridor for birds. The Baltic Sea is sensitive to nutrient pollution, making effective wastewater treatment crucial for preventing eutrophication and preserving marine ecosystems.
