Ulanow Wastewater Treatment Plant: Serving Ulanów, Poland

The Ulanow wastewater treatment plant is located in the town of Ulanów, in the podkarpackie province of southeastern Poland. It serves a population of approximately 2,800 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the region's municipal wastewater infrastructure. As a secondary treatment facility, Ulanow meets the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 8,030 cubic meters per day, with a reported discharge volume of 400.8 cubic meters per day, indicating it operates well below its maximum capacity. This suggests the plant has room to accommodate future population growth or increased flows. The treated effluent from Ulanow 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 San River basin from untreated wastewater, supporting aquatic life and downstream water quality in this ecologically sensitive region.

The Ulanow plant discharges into local streams that feed the San River, a major tributary of the Vistula River. The Vistula flows northward through Poland into the Baltic Sea. The San River basin supports diverse aquatic habitats and is important for migratory fish species. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality in this inland watershed.
