OS JAGIELLY Wastewater Treatment Plant, Bojszowy, Silesian Voivodeship

OS JAGIELLY is an advanced wastewater treatment plant located in Bojszowy, within the Silesian Voivodeship of southern Poland. The facility serves a population of 3,170, classifying it as a small agglomeration under Polish and EU regulations. It operates as part of the municipal wastewater infrastructure for the Bojszowy area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its design capacity is 3,733 m³/day, with a current discharge volume of 451.99 m³/day, indicating significant spare capacity. As a Polish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on receiving water sensitivity. The treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, flowing northward to the Baltic Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems, particularly in the ecologically sensitive region of Upper Silesia, which faces pressures from industrial and urban activities.

The plant discharges into the local drainage network within the Vistula River basin, which flows through southern and central Poland before reaching the Baltic Sea. The region's watershed supports diverse aquatic life and is important for migratory fish species. Advanced treatment at this facility reduces nutrient loading, helping to mitigate eutrophication risks in downstream water bodies.
