Oczyszczalnia sciekow Bolewice - Secondary Wastewater Treatment Plant in Bolewice, Poland

Oczyszczalnia sciekow Bolewice is a municipal wastewater treatment plant located in Bolewice, a village in the Wielkopolskie region of Poland. The plant serves a population of approximately 2,500, placing it in the small agglomeration category under Polish and EU regulations. It operates with a designed capacity of 1,500 m³ per day and currently treats a discharge volume of 357.32 m³ per day, indicating ample reserve capacity. 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. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. As a Polish facility, it operates under national water law and is subject to environmental permits issued by the Regional Water Management Board (RZGW). The treated effluent is discharged into local surface waters, likely a small stream or river within the Warta River basin, which ultimately flows into the Oder River and then the Baltic Sea. The plant plays a key role in protecting local water quality and supporting the ecological health of the downstream aquatic environment.

The plant discharges into a local watercourse within the Warta River basin, part of the larger Oder River catchment that drains into the Baltic Sea. The downstream environment includes sensitive aquatic habitats that support diverse fish and invertebrate communities. Effective secondary treatment helps reduce nutrient and organic loads, mitigating eutrophication risks in the Baltic Sea, which is particularly vulnerable to nitrogen and phosphorus pollution.
