Szebnie Wastewater Treatment Plant, Sądkowa, Podkarpackie, Poland

Szebnie is a wastewater treatment plant located in Sądkowa, within the gmina Tarnowiec, powiat jasielski, in the Podkarpackie Voivodeship of Poland. The plant serves a population of 2,124 and operates with secondary treatment, a standard for smaller agglomerations under Polish regulations aligned with the EU Urban Waste Water Treatment Directive. As a secondary treatment facility, Szebnie provides biological treatment to reduce organic matter and suspended solids. The plant has a designed capacity of 2,900 m³/day and currently treats an average daily flow of 302.85 m³/day, indicating significant spare capacity for future growth or seasonal variations. The treated effluent is discharged into the local water system, which ultimately drains into the Wisłoka River, a tributary of the Vistula River, and then into the Baltic Sea. The plant plays a key role in protecting the region's water quality and supporting the ecological health of the downstream aquatic environment.

The plant discharges into the Wisłoka River basin, which flows into the Vistula River and eventually the Baltic Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in the Baltic Sea.
