TP 562 of Rajamaki Wastewater Treatment Plant, Klaukkala, Finland

TP 562 of Rajamaki is a municipal wastewater treatment plant located in Klaukkala, within the Uusimaa region of southern Finland. It serves a population of around 37,000, classifying it as a medium-sized agglomeration under EU standards. The plant is situated in the Viirinlaakso area, part of the Nurmijärvi municipality, and plays a key role in managing local wastewater. As a Finnish facility, TP 562 operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the community's wastewater load. Treatment processes typically include mechanical, biological, and chemical stages to meet stringent effluent quality standards. The treated effluent is discharged into local water bodies that drain into the Gulf of Finland, part of the Baltic Sea. The Baltic Sea is a sensitive marine environment with eutrophication challenges, making nutrient removal critical. The plant's operations help protect downstream ecosystems, including rivers and coastal areas, from pollution.

TP 562 of Rajamaki discharges into the local watershed that flows through the Vantaa River basin and ultimately into the Gulf of Finland, a sub-basin of the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient loading. Effective wastewater treatment at this plant helps reduce phosphorus and nitrogen inputs, supporting the health of downstream aquatic habitats and mitigating eutrophication risks.
