Racborowice Dolne Wastewater Treatment Plant - Lower Silesia, Poland

Racborowice Dolne is a wastewater treatment plant located in the village of Raciborowice Dolne, within gmina Warta Bolesławiecka, powiat bolesławiecki, in the Lower Silesian Voivodeship (województwo dolnośląskie) of Poland. The plant serves a small population of 795 residents, reflecting its role in a rural community. The facility provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant's designed capacity of 2600 m³/day indicates it can handle peak flows, while the current discharge volume of 113.36 m³/day suggests low utilization relative to capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Odra River basin, which flows northward to the Baltic Sea. The plant's operation helps protect the region's surface waters from nutrient pollution, supporting aquatic ecosystems in the Odra catchment.

The plant discharges into small streams that feed into the Bóbr River, a tributary of the Odra River. The Odra flows through western Poland and empties into the Szczecin Lagoon and the Baltic Sea. This watershed supports diverse aquatic life, including fish species such as pike and perch, and is an important ecological corridor in the region. The secondary treatment provided by the plant reduces organic load and nutrients, helping to maintain water quality in the downstream environment.
