Overview
Swinoujscie wastewater treatment plant serves over 105,000 people in Świnoujście, Poland. Located in the West Pomeranian Voivodeship, it is within 50 km of the Baltic Sea coast.
The Swinoujscie wastewater treatment plant is a key municipal facility serving the city of Świnoujście in the West Pomeranian Voivodeship of Poland. With a population equivalent of over 105,000, it is classified as a large agglomeration under Polish and EU regulations. The plant is situated in the Dalimierz district and plays a vital role in managing wastewater from this Baltic Sea port city. As a large agglomeration, the plant is required to meet stringent treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment as a minimum, and tertiary treatment for discharges into sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a substantial infrastructure to handle the city's wastewater load. The treated effluent is discharged into the Baltic Sea via local waterways, contributing to the protection of the marine environment. The plant's proximity to the coast underscores the importance of effective treatment to prevent nutrient pollution and safeguard the sensitive coastal ecosystem, which supports diverse aquatic life and is an important area for tourism and fisheries.
Environmental context
The plant's discharge ultimately reaches the Baltic Sea, a semi-enclosed brackish sea with limited water exchange, making it highly sensitive to nutrient loading. The local watershed includes the Świna River and the Szczecin Lagoon, which are important ecological corridors for migratory birds and fish. Effective wastewater treatment is crucial to prevent eutrophication and protect the marine biodiversity of the Baltic Sea.
Frequently asked questions
The Swinoujscie wastewater treatment plant is located in the Dalimierz district of Świnoujście, in the West Pomeranian Voivodeship of Poland. It serves the city of Świnoujście, a major port on the Baltic Sea.
The plant serves a population equivalent of over 105,000 people, classifying it as a large agglomeration under EU regulations.
The treated wastewater is discharged into the Baltic Sea via local waterways, likely through the Świna River or the Szczecin Lagoon. The plant's proximity to the coast requires advanced treatment to protect the sensitive marine environment.
As a Polish plant serving a large agglomeration, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment and, for sensitive areas like the Baltic Sea, tertiary treatment to reduce nutrients.
Under the EU UWWTD, plants serving over 100,000 people (large agglomerations) must provide at least secondary treatment. For discharges into sensitive areas such as the Baltic Sea, tertiary treatment (nutrient removal) is required to prevent eutrophication.
