Dobroszyce Wastewater Treatment Plant, województwo dolnośląskie, Poland

The Dobroszyce wastewater treatment plant is located in the village of Dobroszyce, within the powiat oleśnicki of województwo dolnośląskie, Poland. It serves a small population of 2,644 and operates as a municipal facility for the local community. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity of 8,100 m³/day indicates it can handle peak flows, while the current discharge volume of 376.99 m³/day suggests it operates well below capacity. The treated effluent is discharged into local watercourses that eventually drain into the Oder River basin, which flows north 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.

The plant's discharge enters small streams in the Oder River catchment, which flows through southwestern Poland before reaching the Baltic Sea. This region's water bodies support diverse aquatic ecosystems, including fish and macroinvertebrate communities. Proper treatment helps prevent nutrient enrichment and maintains ecological balance in the downstream river system.
