Pustków Żurawski Wastewater Treatment Plant | Secondary Treatment in Lower Silesia

Pustków Żurawski wastewater treatment plant is located in the village of Pustków Żurawski, within gmina Kobierzyce, powiat wrocławski, in the Lower Silesian Voivodeship of Poland. The plant serves a population of 1,248 and operates at a secondary treatment level, meeting the standard required for small agglomerations under Polish and EU regulations. The plant has a designed capacity of 1,783 m³/day and currently discharges 177.95 m³/day of treated effluent. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations under 2,000 population equivalent are generally required to have appropriate treatment, which secondary treatment fulfills. The treated effluent is discharged into local watercourses that eventually drain into the Odra River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the region's surface waters from untreated sewage, supporting aquatic life and downstream water quality in the Odra catchment.

The plant discharges into small streams within the Odra River basin, which flows through southwestern Poland and eventually reaches the Baltic Sea. The Odra basin supports diverse aquatic ecosystems, including fish spawning grounds and migratory corridors. Protecting this watershed from nutrient and organic pollution is critical for maintaining water quality in the Baltic Sea, which faces eutrophication challenges from agricultural and urban runoff.
