Overview
TP 332 of Kristiinankaupungin kt is a municipal wastewater treatment plant in Kristinestad, Österbotten, Finland, serving approximately 7,900 people. It is located within 50 km of the coast and operates under Finnish and EU regulations.
TP 332 of Kristiinankaupungin kt is a municipal wastewater treatment plant located in Kristinestad, a town in the Österbotten region of western Finland. The plant serves a population of approximately 7,900 people, placing it in the small to medium agglomeration category under EU classification. As a Finnish wastewater treatment facility, the plant is subject to 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 a sensitive area. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Bothnia, a brackish sea arm of the Baltic Sea. The Baltic Sea is ecologically sensitive due to its limited water exchange and vulnerability to eutrophication. The plant's operation contributes to protecting the coastal and marine environment from nutrient pollution.
Environmental context
The plant discharges into the local water system that flows into the Gulf of Bothnia, part of the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it highly susceptible to eutrophication from nutrient inputs. The plant's treatment performance is therefore critical for maintaining water quality in the coastal zone and supporting diverse aquatic life, including fish populations and migratory bird species that rely on the region's wetlands.
Frequently asked questions
The plant is located in Kristinestad, a town in the Österbotten region of western Finland, near the coast of the Gulf of Bothnia.
