Ryczywol Wastewater Treatment Plant, Bytyń, Poland

The Ryczywol wastewater treatment plant is located in Bytyń, within the Wielkopolskie Voivodeship of Poland. It serves a population of approximately 5,122 people, classifying it as a small to medium agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater management infrastructure. 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 5,425 m³/day and an actual discharge volume of 730.32 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, which ultimately drains into the Warta River basin and then into the Oder River, flowing into the Baltic Sea. The plant plays a key role in protecting the local watershed from pollution, supporting aquatic life and downstream water quality in the region.

The plant discharges into a local watercourse that is part of the Warta River basin, a major tributary of the Oder River. The Oder flows into the Szczecin Lagoon and then the Baltic Sea. This watershed supports diverse aquatic ecosystems and is important for migratory fish species. The secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in downstream waters.
