Strykowo Wastewater Treatment Plant, Łubnica, Wielkopolska, Poland

The Strykowo wastewater treatment plant is located in Łubnica, within the Wielkopolska region of Poland. It serves a population of approximately 1,832 people, making it a small agglomeration under Polish and EU classification. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. 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. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 2,660 m³/day and currently treats an average daily volume of 261.21 m³, indicating significant spare capacity. The treated effluent is discharged into a local watercourse, which ultimately drains into the Oder River basin and then into the Baltic Sea. The plant plays a key role in protecting local water quality and supporting the ecological health of the downstream environment, including the Oder estuary and Baltic Sea coastal zone.

The plant discharges into a local stream that feeds into the Oder River basin, which flows northward into the Baltic Sea. The Oder basin supports diverse aquatic life and is an important migratory corridor for fish species. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The plant's secondary treatment helps reduce organic and nutrient loads, contributing to the protection of downstream ecosystems.
