OS CHEMIKoW Wastewater Treatment Plant, Nowe Bojszowy, Silesian Voivodeship, Poland

OS CHEMIKoW is a wastewater treatment plant located in Nowe Bojszowy, within the Górnośląsko-Zagłębiowska Metropolia in the Silesian Voivodeship of Poland. The plant serves a population of 8,647, classifying it as a small to medium agglomeration under Polish and EU regulations. As a plant in the European Union, OS CHEMIKoW is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive requires secondary biological treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000, which aligns with the plant's served population. The plant's design and operation are expected to meet these standards to protect the local water environment. The treated effluent from OS CHEMIKoW is discharged into the local watershed, which ultimately drains into the Vistula River basin. The Vistula flows northward through Poland and empties into the Baltic Sea. The plant plays a crucial role in maintaining water quality in the region, supporting both ecological health and downstream communities.

OS CHEMIKoW discharges into the local tributaries of the Vistula River, which flows through southern Poland and into the Baltic Sea. The watershed supports diverse aquatic life and is an important ecological corridor. The plant's operation helps reduce nutrient and pollutant loads, protecting downstream ecosystems and water quality in the Baltic Sea region.
