Overview
Sieniawa wastewater treatment plant serves the town of Ubieszyn in Podkarpackie Voivodeship, Poland. It provides secondary treatment for a population of 2,552 and has a designed capacity of 6,138 m³/day.
Sieniawa wastewater treatment plant is located in Ubieszyn, a village in the Tryńcza commune of Przeworsk County, Podkarpackie Voivodeship, southeastern Poland. The facility serves a population of 2,552 and is part of the region's municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. With a designed capacity of 6,138 m³/day and an average discharge volume of 363.88 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the San River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting the water quality of the San River basin and the downstream aquatic ecosystems.
