Gminna Oczyszczalnia Sciekow - Jeżowe Wastewater Treatment Plant, Poland

Gminna Oczyszczalnia Sciekow is a municipal wastewater treatment plant located in Jeżowe, a village in the Podkarpackie Voivodeship of southeastern Poland. The plant serves a population of approximately 3,516 residents, classifying it as a small agglomeration under Polish and EU regulations. As a primary treatment facility, the plant provides basic mechanical treatment including screening and sedimentation. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are generally required to provide secondary treatment, though primary treatment may be acceptable in certain less sensitive areas or as a transitional measure. The plant's designed capacity of 3,525 m³/day indicates it is sized to handle the community's wastewater load. The treated effluent is discharged into local watercourses that ultimately drain into the San River basin, a tributary of the Vistula River. The Vistula flows northward through Poland into the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's aquatic ecosystems.

The plant discharges into the San River basin, which flows into the Vistula River and eventually reaches the Baltic Sea. The local watershed includes small streams and agricultural areas, where nutrient and pathogen removal is important to prevent eutrophication and protect downstream aquatic life. The region supports diverse freshwater habitats and migratory fish species.
