Overview
WOS Janowek is a major wastewater treatment plant serving Wrocław, Poland, with a population equivalent of 647,997. It operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with stringent discharge standards.
WOS Janowek is a large wastewater treatment plant located in the Janówek district of Wrocław, in the Lower Silesian Voivodeship of Poland. Serving a population of approximately 648,000, it is classified as a large agglomeration under EU regulations, requiring advanced treatment to protect sensitive water bodies. As a plant of this scale in Poland, WOS Janowek is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum and tertiary treatment for discharges into sensitive areas. The plant's operations are likely overseen by the local water authority, with permits issued by the Regional Water Management Board in Wrocław. The treated effluent from WOS Janowek is discharged into the Oder River basin, which flows through Wrocław and eventually reaches the Baltic Sea. The Oder is a major European river supporting diverse aquatic life and providing drinking water for millions. The plant plays a crucial role in maintaining water quality in this ecologically important watershed.
Environmental context
WOS Janowek discharges into the Oder River, which flows northward through Poland and Germany before emptying into the Baltic Sea via the Szczecin Lagoon. The Oder basin supports a variety of fish species, including salmon and sturgeon, and is an important migratory corridor. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Effective treatment at WOS Janowek helps reduce eutrophication risks in the Baltic.
