TP 852 of Teuvan kk Wastewater Treatment Plant, Teuva, Finland

TP 852 of Teuvan kk is a municipal wastewater treatment facility located in Teuva, within the Etelä-Pohjanmaa region of Finland. The plant serves a population of approximately 3,400 residents, making it a small-scale treatment facility. It operates under Finland's national environmental regulations, which align with the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which include nutrient removal and disinfection, ensuring high-quality effluent. The plant's advanced treatment level indicates compliance with stringent standards for sensitive areas. Finland's regulatory framework mandates tertiary treatment for plants serving over 10,000 population equivalents in sensitive regions, but smaller plants like this one also often adopt advanced methods to protect local water bodies. The treated wastewater is discharged into nearby streams and rivers that flow through the Suupohja region, eventually reaching the Gulf of Bothnia. This discharge supports the ecological health of the watershed, which is important for local biodiversity and recreational use. The plant's advanced treatment helps minimize nutrient loading and protects downstream aquatic habitats.

The plant discharges into local watercourses that are part of the drainage basin feeding the Gulf of Bothnia, a brackish sea area of the Baltic Sea. The region's watershed supports diverse aquatic life, including fish species like salmon and trout, and is an important migratory corridor. Advanced treatment at this plant reduces phosphorus and nitrogen loads, helping to prevent eutrophication in the sensitive coastal waters of the Baltic Sea.
