TP 839 of Tammisaaren kt, Raseborg

Overview

TP 839 of Tammisaaren kt serves 13,100 people in Raseborg, Finland. The plant operates under EU Urban Waste Water Treatment Directive requirements for medium agglomerations.

TP 839 of Tammisaaren kt is a municipal wastewater treatment plant located in Raseborg, in the Uusimaa region of southern Finland. The plant serves a population of approximately 13,100, classifying it as a medium agglomeration under Finnish and EU regulations. Its location near the coast of the Gulf of Finland places it in a sensitive environmental zone. As a Finnish plant serving over 10,000 people, TP 839 is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For plants in sensitive areas, such as coastal zones, tertiary treatment may be mandated to reduce nutrient loads. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating adequate capacity for its service population. The plant's treated effluent is discharged into the Baltic Sea via the Gulf of Finland, a brackish water body with limited water exchange. This discharge contributes to nutrient loading in the Baltic Sea, which is highly sensitive to eutrophication. The plant's performance is critical for protecting local coastal waters and the broader marine ecosystem.

Environmental context

The plant discharges into the Gulf of Finland, part of the Baltic Sea, a semi-enclosed sea with high ecological sensitivity to nutrient pollution. The Baltic Sea suffers from eutrophication due to nitrogen and phosphorus inputs from surrounding countries. The plant's location within 50 km of the coast means its effluent directly affects coastal water quality and marine habitats, including spawning grounds for fish and migratory bird routes.

Frequently asked questions

TP 839 of Tammisaaren kt is located in Raseborg, in the Uusimaa region of southern Finland, near the coast of the Gulf of Finland.

The plant serves approximately 13,100 people, classifying it as a medium agglomeration under EU regulations.

The plant discharges treated effluent into the Gulf of Finland, which is part of the Baltic Sea. Its coastal location requires compliance with strict nutrient removal standards to protect the sensitive marine environment.

As a Finnish plant serving over 10,000 people, TP 839 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment and, in sensitive coastal areas, tertiary treatment for nutrient removal.

In Finland, plants of this scale typically employ biological treatment with nutrient removal (nitrogen and phosphorus) to meet EU standards, especially in coastal zones where eutrophication is a concern.
