OS Foch III is a municipal wastewater treatment plant located in Knurów, within the Silesian Voivodeship of southern Poland. The plant serves an estimated population of 29,659, placing it in the medium agglomeration category under EU classification. It is situated in the Górnośląsko-Zagłębiowska Metropolia, a densely urbanized and industrialized region. As a Polish facility, OS Foch III operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The plant's treatment processes are expected to meet these standards, ensuring compliance with national and European regulations for wastewater management. The treated effluent from OS Foch III is discharged into local watercourses that ultimately drain into the Oder River basin, which flows northward to the Baltic Sea. The plant plays a critical role in protecting the region's water quality, particularly given the industrial and mining activities in Upper Silesia that can impact local watersheds. Its operation supports the ecological health of downstream rivers and the Baltic Sea ecosystem.
Environmental context
OS Foch III discharges into the Oder River basin, which flows through Poland and Germany before reaching the Baltic Sea. The region's water bodies support diverse aquatic life and are important for migratory fish species. The plant's treatment helps mitigate pollution from urban and industrial sources in the Silesian metropolitan area, contributing to the ecological integrity of downstream environments.
