Overview
TP 579 of Paraisten kt serves Pargas, Finland, treating wastewater for approximately 19,000 people. The plant operates under Finland's implementation of the EU Urban Waste Water Treatment Directive.
TP 579 of Paraisten kt is a municipal wastewater treatment plant located in Pargas, in the Varsinais-Suomi region of Finland. The plant serves a population of around 19,000 residents in this coastal town in the Turku archipelago. As part of Finland's wastewater infrastructure, it plays a key role in protecting the local environment. The plant is designed with a capacity of 1.00 (likely in thousands of cubic meters per day or similar units). Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size (10,000-100,000 population equivalent) are required to have secondary treatment, with more advanced treatment if discharging into sensitive areas. Finland's national regulations align with these standards, ensuring adequate treatment for the receiving waters. The treated effluent from the plant is discharged into the Baltic Sea via the Archipelago Sea, a sensitive marine environment. The Archipelago Sea is known for its rich biodiversity and is an important area for fish spawning and bird migration. Proper wastewater treatment is critical to prevent eutrophication and protect this fragile ecosystem.
Environmental context
The plant discharges into the Archipelago Sea, part of the Baltic Sea, which is a brackish water body with limited water exchange, making it highly sensitive to nutrient pollution. The surrounding area includes numerous islands and shallow waters that support diverse aquatic life, including fish, seabirds, and marine vegetation. Effective wastewater treatment is essential to reduce nutrient loads and prevent algal blooms in this ecologically significant region.
Frequently asked questions
TP 579 of Paraisten kt is located in Pargas, in the Varsinais-Suomi region of Finland, near the coast of the Archipelago Sea.
The plant serves approximately 19,000 residents in Pargas and surrounding areas.
The treated wastewater is discharged into the Archipelago Sea, which is part of the Baltic Sea. The plant's discharge contributes to the overall water quality in this sensitive marine environment.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Finland's national regulations implement this directive, with additional requirements for sensitive areas like the Archipelago Sea.
For agglomerations of 10,000-100,000 population equivalent, the EU UWWTD mandates secondary treatment. In Finland, plants in coastal areas may also require tertiary treatment to reduce nutrients, especially when discharging into the Baltic Sea, which is designated as a sensitive area under the directive.
