Radwanowice Wastewater Treatment Plant | małopolskie, Poland

Radwanowice wastewater treatment plant is located in the village of Radwanowice, within gmina Zabierzów, powiat krakowski, in the małopolskie province of southern Poland. The facility serves a small population of 242 residents, reflecting its role in a rural community. The plant operates under Polish regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant provides secondary treatment, meeting the minimum standard for discharges into inland waters under EU law. Its designed capacity of 765 m³/day is significantly higher than the current discharge volume of 34.51 m³/day, indicating ample reserve for future growth or seasonal peaks. The plant's capacity utilization is low, suggesting it is not under stress. The treated effluent is discharged into a local watercourse that ultimately drains into the Vistula River basin, which flows northward to the Baltic Sea. The plant's operations help protect the local aquatic environment from nutrient pollution, supporting water quality in the region's streams and rivers.

The plant discharges into a small stream that is part of the Vistula River basin. The Vistula flows through southern and central Poland before emptying into the Baltic Sea via the Gdańsk Bay. The local watershed includes agricultural and forested areas, and the plant's secondary treatment helps reduce organic load and nutrient inputs, protecting downstream aquatic habitats and the sensitive Baltic Sea ecosystem from eutrophication.
