TP 1900009451 of Pyhannan kk is a municipal wastewater treatment plant located in Siikalatva, within the Pohjois-Pohjanmaa region of Finland. The plant serves a population of approximately 16,700, placing it in the medium agglomeration category under EU classification. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving populations between 10,000 and 100,000 are required to provide secondary treatment as a minimum. Finland's national regulations align with this directive, and the plant is expected to meet these standards. The regulatory framework ensures appropriate treatment for the population served. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Baltic Sea via the Oulujoki river system. The Baltic Sea is a sensitive marine environment with eutrophication concerns, making effective nutrient removal important for plants in this region.
Environmental context
The plant is located inland in the Pohjois-Pohjanmaa region, with its treated effluent entering the local watershed that flows through the Oulujoki river system before reaching the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it highly sensitive to nutrient inputs. Effective treatment at this plant helps reduce the risk of eutrophication in downstream waters.
