Radomysl nad Sanem Wastewater Treatment Plant - Żabno, Podkarpackie, Poland

The Radomysl nad Sanem wastewater treatment plant is located in Żabno, within the gmina of Radomyśl nad Sanem in the Podkarpackie region of Poland. This facility serves a small community of 171 residents, reflecting the rural character of the area. As a secondary treatment plant, it meets the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 4128 cubic meters per day, with a current discharge volume of 24.38 cubic meters per day, indicating ample reserve capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the San River, a tributary of the Vistula River. The Vistula flows northward into the Baltic Sea, making this plant part of the broader Baltic Sea catchment area. Proper treatment helps protect downstream aquatic ecosystems.

The plant's discharge enters the local drainage network that feeds into the San River, a major right-bank tributary of the Vistula. The Vistula River basin supports diverse aquatic life and provides important ecosystem services. The Baltic Sea, as the ultimate receiving water body, is sensitive to nutrient pollution, making secondary treatment crucial for reducing eutrophication risks.
