Overview
TP 999999999001 of Maarianhaminan kt serves 22,000 people in Jomala, Åland, Finland. The plant discharges into the Baltic Sea via local waterways, operating under EU Urban Waste Water Treatment Directive standards.
TP 999999999001 of Maarianhaminan kt is a municipal wastewater treatment plant located in Jomala, within the Åland region of Finland. It serves a population of approximately 22,000, classifying it as a medium agglomeration under EU regulations. The plant is situated near the coast, reflecting the island geography of Åland. As a facility in Finland, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters sensitive areas, which may apply given the proximity to the Baltic Sea. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day), indicating adequate infrastructure for the served population. The treated effluent is discharged into the Baltic Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The plant plays a key role in protecting the marine environment of the Archipelago Sea and the broader Baltic ecosystem, which supports diverse aquatic life and is an important migratory corridor for birds.
Environmental context
The plant discharges into the Baltic Sea via local streams and coastal waters. The Baltic Sea is a brackish, semi-enclosed sea with high ecological sensitivity due to limited water exchange and vulnerability to eutrophication. The surrounding Archipelago Sea area supports diverse marine life, including fish spawning grounds and bird habitats. Effective wastewater treatment is critical to reducing nutrient loads that cause algal blooms and oxygen depletion in this fragile ecosystem.
Frequently asked questions
The plant is located in Jomala, within the Åland region of Finland, near the coast of the Baltic Sea.
The plant serves approximately 22,000 people, classifying it as a medium-sized agglomeration under EU regulations.
Treated wastewater is discharged into the Baltic Sea via local waterways, contributing to the protection of the sensitive marine environment.
As a Finnish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size and may require advanced treatment for discharges into sensitive areas like the Baltic Sea.
Under the EU UWWTD, plants serving over 10,000 people in sensitive areas typically require secondary treatment with nutrient removal. In Finland, many such plants also employ advanced treatment to reduce phosphorus and nitrogen loads to the Baltic Sea.
