Oczyszczalnia na Os Zamość - Wronki Wastewater Treatment Plant, Poland

Oczyszczalnia na Os Zamość is a wastewater treatment plant located in the Zamość district of Wronki, within the Wielkopolskie Voivodeship of Poland. The plant serves a population of approximately 1,454 people, making it a small-scale facility in the region. It is situated near the Nadwarciańska area, reflecting its integration into the local municipal infrastructure. The plant provides secondary treatment, which is the standard biological treatment stage required under Polish and EU regulations for agglomerations of this size. With a designed capacity of 1,821 m³/day and an actual discharge volume of 207.32 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. Secondary treatment typically involves biological oxidation and sedimentation. The treated effluent is discharged into the local water system, which ultimately drains into the Warta River, a major tributary of the Oder River. The Warta River flows through the Wielkopolska region and supports diverse aquatic life. The plant's operation helps protect downstream water quality in the Oder basin, which is ecologically significant for both Poland and the Baltic Sea.

The plant discharges into the local watershed that feeds the Warta River, a key tributary of the Oder River. The Oder River flows into the Baltic Sea, making the plant part of a transboundary water system. The Warta River valley supports diverse habitats, including wetlands and riparian zones that are important for migratory birds and fish species. Proper treatment at this plant helps reduce nutrient loads and organic pollution, contributing to the ecological health of the downstream environment.
