Szamocin Wastewater Treatment Plant | Secondary Treatment, Poland

The Szamocin wastewater treatment plant is located in Szamocin, a town in the Greater Poland Voivodeship of Poland. It serves a population of approximately 3,044, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the local municipal infrastructure. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 7,500 m³/day and an actual discharge volume of 434.03 m³/day, the plant operates well below its capacity, indicating potential for future growth. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a river or stream within the Warta River basin, which ultimately drains into the Oder River and then the Baltic Sea. The plant plays a key role in protecting local water quality and supporting the ecological health of the downstream environment, which includes agricultural and natural areas.

The Szamocin plant discharges into a local watercourse within the Warta River basin, part of the larger Oder River system that flows into the Baltic Sea. The surrounding region is characterized by agricultural land and small water bodies, making the plant's secondary treatment essential for preventing nutrient pollution and maintaining aquatic biodiversity. The Baltic Sea is sensitive to eutrophication, so effective wastewater treatment in inland plants like Szamocin contributes to reducing nutrient loads reaching the sea.
