Overview
TP 561 of Nurmijarven kk serves approximately 7,000 people in Nurmijärvi, Uusimaa, Finland. The plant operates under Finland's implementation of the EU Urban Waste Water Treatment Directive.
TP 561 of Nurmijarven kk is a wastewater treatment plant located in Nurmijärvi, a municipality in the Uusimaa region of southern Finland. The plant serves a population of around 7,000 residents, placing it in the small-to-medium agglomeration category under Finnish and EU regulations. Finland implements the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating a facility scaled to handle local municipal wastewater. The plant discharges treated effluent into local watercourses that eventually drain into the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is a sensitive brackish water body with eutrophication concerns, making nutrient removal important for plants in the region. The facility contributes to protecting downstream aquatic ecosystems and the broader Baltic Sea environment.
Environmental context
The plant's treated effluent flows into small streams in the Nurmijärvi area, which are part of the Vantaanjoki river basin. The Vantaanjoki River drains into the Gulf of Finland near Helsinki, a region ecologically significant for fish spawning and migratory birds. The Baltic Sea, as the ultimate receiving water body, faces challenges from nutrient loading, so effective wastewater treatment helps mitigate eutrophication and supports marine biodiversity.
