Cieszanow Wastewater Treatment Plant, Borchów, Podkarpackie, Poland

The Cieszanow wastewater treatment plant is located in Borchów, within the gmina Oleszyce in Podkarpackie, Poland. It serves a population of 3,296, making it a small-scale municipal facility under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the region's water management infrastructure. As a secondary treatment facility, Cieszanow 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 8,028 m³/day and currently treats an average daily volume of approximately 470 m³, indicating ample reserve capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies, which ultimately drain into the broader Vistula River basin. This discharge supports the ecological balance of the region's rivers and streams, contributing to the protection of downstream aquatic habitats. The plant plays a key role in preventing untreated wastewater from entering the environment, thereby safeguarding water quality in the Podkarpackie region.

The plant discharges into local streams that are part of the Vistula River basin, which flows into the Baltic Sea. The region's watershed supports diverse aquatic life and is important for maintaining water quality in downstream ecosystems. The plant's secondary treatment helps reduce nutrient loads, protecting against eutrophication in the Baltic Sea.
