TP 1900013730 of Karjaan kt Wastewater Treatment Plant, Raseborg, Finland

TP 1900013730 of Karjaan kt is a municipal wastewater treatment plant located in Raseborg, Uusimaa, Finland. It serves a population of approximately 10,200 people, classifying it as a medium agglomeration under EU regulations. The plant is situated near the coast in the southern part of the country. As a Finnish plant serving over 10,000 people, it is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive mandates that agglomerations of this size provide at least secondary treatment before discharge. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating a facility sized for its service population. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it sensitive to nutrient pollution. The plant's operation helps protect the coastal environment and supports the ecological health of the region.

The plant's treated effluent flows into the local watercourses that drain into the Gulf of Finland, a sensitive brackish sea with limited water exchange. The Baltic Sea is prone to eutrophication from nutrient inputs, making effective wastewater treatment critical. The surrounding Uusimaa region features coastal habitats that support diverse aquatic life and migratory bird populations.
