Jeziorzany Wastewater Treatment Plant, Jeziorzany, Poland

The Jeziorzany wastewater treatment plant is located in the village of Jeziorzany, within the gmina of the same name, in powiat lubartowski, województwo lubelskie, Poland. It serves a small population of 1,269 residents, reflecting its role in a rural community. The plant is situated inland, away from coastal areas, and its operations are part of the local municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 3,450 m³/day and currently discharges 180.94 m³/day, indicating it operates well below its capacity. The treated effluent is discharged into a local water body, which ultimately drains into the Tyśmienica River, a tributary of the Wieprz River, and then into the Vistula River basin. The Vistula flows northward into the Baltic Sea. The plant's operations help protect the local watershed and downstream aquatic ecosystems from untreated wastewater pollution.

The Jeziorzany plant discharges into a local watercourse that feeds into the Tyśmienica River, a tributary of the Wieprz River, which is part of the Vistula River basin. The Vistula River flows into the Baltic Sea, making the plant's treatment performance important for the health of downstream aquatic habitats. The region's watershed supports diverse freshwater species and is an important ecological corridor in eastern Poland.
