Overview
The Żarów wastewater treatment plant in Dolnośląskie, Poland, serves a population of 1,569 with secondary treatment. It discharges 223.72 m³/day and has a designed capacity of 39,217 m³/day.
The Żarów wastewater treatment plant is located in the town of Żarów, within the województwo dolnośląskie (Lower Silesian Voivodeship) in southwestern Poland. This facility serves a population of approximately 1,569 people, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 39,217 m³/day and an actual discharge volume of 223.72 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. 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.
Environmental context
The plant discharges into the Odra River basin, which flows through Poland and Germany before reaching the Baltic Sea. This watershed supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The secondary treatment provided helps reduce organic pollutants and nutrients, mitigating eutrophication risks in the Baltic Sea.
