TP 403 of Lievestuore is an advanced wastewater treatment plant in Lievestuore, Keski-Suomi, Finland, serving 2,400 people. It discharges 393.35 m³/day of treated wastewater near the coast.
TP 403 of Lievestuore is an advanced wastewater treatment facility located in Lievestuore, a locality in the Keski-Suomi region of Finland. The plant serves a population of approximately 2,400 residents and is situated near the coast, reflecting the region's lake-rich landscape. As an advanced treatment plant, it provides tertiary-level purification, which includes nutrient removal to protect sensitive water bodies. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Finland requires advanced treatment for agglomerations over 10,000 population equivalent in sensitive areas, but this smaller plant still meets high standards due to local environmental priorities. The treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Bothnia via the Kymijoki river system. The plant's coastal proximity means its discharge contributes to the ecological health of downstream lakes and the Baltic Sea, supporting aquatic biodiversity and recreational water quality.
Environmental context
The plant discharges into the inland waters of the Kymijoki basin, which flows into the Gulf of Bothnia, a part of the Baltic Sea. This region is ecologically sensitive due to nutrient loading and eutrophication risks. Advanced treatment helps reduce phosphorus and nitrogen inputs, protecting downstream lakes and coastal habitats that support fish populations and migratory birds.
