Overview
TP 101 of Helsingin kt serves 1,110,000 people in Helsinki, Finland. The plant operates under EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates advanced treatment for large agglomerations discharging into sensitive areas.
TP 101 of Helsingin kt is a major wastewater treatment plant located in Helsinki, Uusimaa, Finland. It serves a population of 1,110,000, making it a large agglomeration under EU classification. The plant is situated in the coastal region of the Gulf of Finland, part of the Baltic Sea. As a large agglomeration, the plant is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires tertiary treatment for discharges into sensitive areas like the Baltic Sea. The designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating substantial infrastructure to handle the wastewater from Finland's capital region. The treated effluent is discharged into the Gulf of Finland, a brackish water body that is part of the Baltic Sea. The Baltic Sea is ecologically sensitive due to its limited water exchange and vulnerability to eutrophication. The plant plays a critical role in protecting this marine environment by reducing nutrient loads and preventing pollution.
Environmental context
The plant discharges into the Gulf of Finland, which connects to the Baltic Sea via the Baltic Sea proper. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it highly susceptible to eutrophication from nutrient inputs. Helsinki's coastal location means that treated wastewater must meet stringent standards to protect the fragile marine ecosystem, which supports diverse aquatic life and is an important migratory corridor for fish and birds.
