Winsko Wastewater Treatment Plant, Wińsko, Poland

The Winsko wastewater treatment plant is located in Wińsko, a town in the Lower Silesian Voivodeship of Poland. The facility serves a population of approximately 816 residents, making it a small-scale municipal treatment plant. It is situated inland, away from coastal areas, and operates under Polish environmental regulations. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of the plant is 2929 cubic meters, and it currently discharges an average of 116.35 cubic meters of treated wastewater per day. This indicates a utilization rate well below capacity, allowing for future growth. The treated effluent is discharged into local watercourses that eventually drain into the Oder River basin. The Oder River flows northward to the Baltic Sea, passing through ecologically significant areas. The plant's operation helps protect downstream water quality and supports the health of aquatic ecosystems in the region.

The Winsko plant discharges into local streams that are part of the Oder River basin. The Oder River flows through Poland and Germany before reaching the Baltic Sea, supporting diverse aquatic life and serving as an important migratory corridor for fish. The region's watershed is sensitive to nutrient pollution, and the plant's secondary treatment helps reduce organic load and protect downstream habitats.
