Overview
TP 379 of Laihian kk serves Laihia, Finland, treating wastewater for approximately 8,700 residents. The plant operates under Finnish and EU regulations for municipal wastewater treatment.
TP 379 of Laihian kk is a municipal wastewater treatment plant located in Laihia, Österbotten, Finland. It serves a population of approximately 8,700 people, classifying it as a small to medium agglomeration under EU classification. The plant is situated in the western region of Finland, near the coast of the Gulf of Bothnia. As a Finnish wastewater facility, TP 379 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating its scale relative to the population served. The treated effluent from TP 379 is discharged into local waterways that ultimately flow into the Gulf of Bothnia, part of the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it sensitive to nutrient pollution. Effective wastewater treatment at plants like TP 379 is crucial for reducing eutrophication and protecting the marine ecosystem.
Environmental context
The plant's discharge enters the drainage basin of the Gulf of Bothnia, a northern arm of the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea with slow water turnover, making it highly sensitive to nutrient loading from wastewater. Eutrophication from excess nitrogen and phosphorus is a major ecological concern, leading to algal blooms and oxygen depletion. The local watershed includes agricultural and forested areas, contributing diffuse pollution that combines with point sources like TP 379.
