Bojanow Wastewater Treatment Plant, Stany, Poland - Secondary Treatment Facility

Bojanow wastewater treatment plant is located in the village of Stany, within the gmina of Bojanów in the podkarpackie voivodeship of southeastern Poland. This facility serves a small population of 583 residents, reflecting its role in a rural community. The plant is part of Poland's municipal wastewater infrastructure, which operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Its designed capacity of 8000 m³/day is significantly larger than the current discharge volume of 83.13 m³/day, indicating ample capacity for future growth. Under the EU directive, agglomerations of this size (under 2000 population equivalent) are typically required to have appropriate treatment, and secondary treatment meets that standard. The treated effluent is discharged into local waterways, ultimately draining into the Vistula River basin and then to the Baltic Sea. The surrounding region is characterized by forests and agricultural land, and the plant helps protect local streams and groundwater from nutrient pollution. Proper wastewater management in this area supports the ecological health of the Vistula catchment and the sensitive Baltic Sea ecosystem.

The plant discharges into small streams that flow into the San River, a tributary of the Vistula River, which empties into the Baltic Sea. The local watershed supports diverse aquatic life and is part of a region with significant forest cover. Nutrient removal from wastewater is important to prevent eutrophication in the Baltic Sea, a semi-enclosed sea sensitive to nitrogen and phosphorus loads.
