Proszkow Wastewater Treatment Plant, Prószków, Opole Voivodeship, Poland

The Proszkow wastewater treatment plant serves the town of Prószków in Opole Voivodeship, Poland. It is a municipal facility designed to handle wastewater from a population of approximately 4,350 residents, reflecting its role as a medium-sized agglomeration in the region. The plant operates at secondary treatment level, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 8,500 m³/day and an average discharge volume of 620.24 m³/day, the facility has ample capacity to manage current loads and accommodate future growth. Treated effluent from the plant is discharged into local watercourses that ultimately drain into the Oder River basin. The Oder flows northward to the Baltic Sea, making the plant's performance important for downstream water quality and the ecological health of the Baltic Sea ecosystem.

The plant discharges into the Oder River basin, which flows through Poland and Germany before reaching the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea sensitive to nutrient pollution, and secondary treatment helps reduce organic load and nutrients. The local watershed supports diverse aquatic life and is part of a region with agricultural and industrial activities that can impact water quality.
