Białośliwie Wastewater Treatment Plant | Wielkopolskie, Poland

The Białośliwie wastewater treatment plant is located in the town of Białośliwie, within the Wielkopolskie region of Poland. It serves a population of approximately 2,204 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and plays a key role in managing local domestic wastewater. The facility provides secondary treatment, which is the 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. The plant's designed capacity is 853 m³/day, with an average daily discharge of 314.26 m³/day, indicating operational headroom. The treated effluent is discharged into local watercourses that eventually drain into the Baltic Sea via the Noteć River and the Warta River system. The plant's operation helps protect the region's surface water quality and supports the ecological health of downstream aquatic habitats, which are part of the broader Oder River basin.

The plant discharges into the Noteć River catchment, which flows into the Warta River and ultimately the Oder River before reaching the Baltic Sea. This inland watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment provided helps reduce nutrient loads, mitigating eutrophication risks in downstream waters.
