TP 817 of Suonenjoen kt Wastewater Treatment Plant, Suonenjoki, Finland

TP 817 of Suonenjoen kt is a municipal wastewater treatment plant located in Suonenjoki, within the Pohjois-Savo region of Finland. The plant serves an estimated population of 26,500, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a Finnish facility, the plant is subject to national regulations implementing the EU UWWTD, which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating its scale. Treatment processes are expected to meet the directive's standards for organic matter and nutrient removal. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Kymi River basin or nearby lakes. The Baltic Sea is a sensitive marine environment with eutrophication concerns, making nutrient removal critical. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's lakes and rivers.

The plant discharges into the inland watershed of Pohjois-Savo, which feeds into the Kymi River basin and eventually the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is highly sensitive to nutrient pollution, and Finnish regulations require advanced treatment to reduce phosphorus and nitrogen loads. The surrounding area includes numerous lakes and rivers that support diverse aquatic life and are used for recreation.
