Oczyszczalnia Sciekow w Mosinie - Rogalinek Wastewater Treatment Plant, Greater Poland

Oczyszczalnia Sciekow w Mosinie is a municipal wastewater treatment plant located in Rogalinek, a village within the Mosina commune in the Poznan County of Greater Poland Voivodeship, Poland. The plant serves a population of approximately 26,848 people, placing it in the medium agglomeration category under Polish and EU regulations. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and EU water quality requirements. The treated effluent is discharged into the local river network, which ultimately flows into the Warta River, a major tributary of the Oder River. The Oder River drains into the Baltic Sea, making the plant's operations important for the health of the Baltic Sea ecosystem. The plant helps protect downstream water quality and supports aquatic life in the region's rivers.

The plant discharges into the local river system that feeds into the Warta River, a key waterway in western Poland. The Warta flows into the Oder River, which empties into the Baltic Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The plant's treatment performance is critical for maintaining water quality in this ecologically sensitive river basin.
