Margonin Wastewater Treatment Plant - Secondary Treatment in Wielkopolska, Poland

The Margonin wastewater treatment plant is located in the town of Margonin, in the Wielkopolska region of Poland. It serves a population of approximately 5,161 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive for settlements of this size. The plant has a designed capacity of 995 cubic meters per day and currently discharges an average volume of 735.88 cubic meters per day. As a secondary treatment facility, it effectively removes organic matter and suspended solids, meeting the effluent quality standards set by Polish law and the EU directive. The plant's operations are overseen by the local water authority, ensuring compliance with environmental regulations. The treated wastewater is discharged into local rivers that eventually drain into the Baltic Sea via the Warta and Oder river systems. The plant plays a crucial role in protecting the region's water quality, particularly the downstream aquatic ecosystems. By maintaining secondary treatment standards, Margonin WWTP helps reduce nutrient loads and organic pollution, supporting the ecological health of the Wielkopolska region's waterways.

The Margonin WWTP discharges into local watercourses that flow into the Warta River, a major tributary of the Oder River, which ultimately reaches the Baltic Sea. The region's watershed supports diverse aquatic life and is important for migratory fish species. The plant's secondary treatment helps control nutrient pollution, which is critical for preventing eutrophication in downstream lakes and the Baltic Sea.
