Overview
TP 243 of Kauhavan kt is a municipal wastewater treatment plant in Kauhava, Etelä-Pohjanmaa, Finland, serving approximately 8,800 people. It operates under Finland's national implementation of the EU Urban Waste Water Treatment Directive.
TP 243 of Kauhavan kt is a municipal wastewater treatment facility located in Kauhava, within the Etelä-Pohjanmaa region of western Finland. The plant serves a population of approximately 8,800, placing it in the medium agglomeration category under EU classification. As a Finnish plant, TP 243 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Finland's national regulations, enforced by the Regional State Administrative Agencies, ensure compliance with discharge standards for organic matter, nutrients, and suspended solids. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Gulf of Bothnia, part of the Baltic Sea. The Baltic Sea is a sensitive brackish water body with eutrophication challenges, making nutrient removal a key environmental priority for inland plants in this watershed.
Environmental context
The plant discharges into the Lapuanjoki river basin, which flows through the Ostrobothnia region and empties into the Gulf of Bothnia, a sub-basin of the Baltic Sea. The Baltic Sea is highly sensitive to nutrient pollution, and Finnish regulations mandate advanced treatment for plants in this catchment to reduce phosphorus and nitrogen loads. The surrounding area features agricultural land and forests, contributing diffuse nutrient inputs that the plant helps mitigate.
