Overview
TP 251 of Kempele serves approximately 36,000 people in Pohjois-Pohjanmaa, Finland. The plant is located near the coast and discharges into the Gulf of Bothnia via local waterways.
TP 251 of Kempele is a municipal wastewater treatment plant located in Kempele, within the Pohjois-Pohjanmaa region of Finland. It serves a population of approximately 36,000 residents, classifying it as a medium-sized agglomeration under Finnish and EU regulations. The plant is situated near the coast, within 50 km of the Gulf of Bothnia. As a Finnish plant, TP 251 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Finland has implemented the directive through national legislation, with additional requirements for nutrient removal in sensitive areas. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating it is sized to handle the local wastewater load. The treated effluent from TP 251 is discharged into local watercourses that flow into the Gulf of Bothnia, a brackish sea area of the Baltic Sea. The Baltic Sea is highly sensitive to nutrient pollution, and Finnish plants are subject to stringent phosphorus and nitrogen removal standards to protect this vulnerable marine environment. The plant plays a key role in maintaining water quality in the region.
Environmental context
The plant discharges into local streams that drain into the Gulf of Bothnia, part of the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it highly susceptible to eutrophication from nutrient inputs. Finnish regulations require advanced treatment to reduce phosphorus and nitrogen loads, helping to protect the sensitive coastal ecosystem and support biodiversity in the region.
