Overview

TP 1900015537 of Turun kt serves 420,000 people in Turku, Finland. The plant is located in the Varsinais-Suomi region and discharges into the Archipelago Sea, part of the Baltic Sea.

TP 1900015537 of Turun kt is a major wastewater treatment plant serving the city of Turku, located in the Varsinais-Suomi region of southwestern Finland. With a population equivalent of 420,000, it is one of the largest treatment facilities in the country, handling municipal wastewater from the Turku metropolitan area. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is required to provide at least secondary treatment, with tertiary treatment expected in sensitive areas like the Baltic Sea catchment. The designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a substantial infrastructure to manage the region's wastewater. The treated effluent is discharged into the Archipelago Sea, a part of the Baltic Sea, which is a brackish water body with limited water exchange, making it sensitive to nutrient pollution. The plant plays a critical role in protecting the marine environment from eutrophication, supporting the ecological health of the surrounding coastal and marine ecosystems.

Environmental context

The plant discharges into the Archipelago Sea, which connects to the Baltic Sea via the Gulf of Bothnia. The Baltic Sea is a semi-enclosed brackish sea with slow water renewal, making it highly sensitive to nutrient loading from wastewater. The plant's treatment performance directly affects local coastal waters, which support diverse aquatic life and are important for fisheries and recreation.
