Overview
TP 416 of Tampereen kt serves about 15,000 people in Lempäälä, Pirkanmaa, Finland. The plant operates under Finland's national implementation of the EU Urban Waste Water Treatment Directive.
TP 416 of Tampereen kt is a municipal wastewater treatment plant located in Lempäälä, a town in the Pirkanmaa region of Finland. The plant serves a population of approximately 15,000 residents, placing it in the medium agglomeration category under EU classification. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving between 10,000 and 100,000 population equivalents are required to provide secondary treatment as a minimum. Finland has implemented this directive through national legislation, with oversight by regional authorities. The regulatory framework ensures appropriate treatment standards for this scale. The treated effluent is discharged into local water bodies that ultimately drain into the Baltic Sea via the Kokemäenjoki river system. The Baltic Sea is a sensitive brackish water body with limited water exchange, making nutrient removal important for preventing eutrophication. The plant's location inland, over 50 km from the coast, reduces direct marine impact but still contributes to the overall nutrient load in the watershed.
Environmental context
The plant discharges into the Kokemäenjoki river basin, which flows into the Bothnian Sea, part of the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with high ecological sensitivity to nutrient pollution, particularly nitrogen and phosphorus. Effective wastewater treatment is crucial to mitigate eutrophication and support aquatic life in this vulnerable marine environment.
