Wrzosy Wastewater Treatment Plant, Jordanów, Poland

Wrzosy is a wastewater treatment plant located in the Osiedle Wrzosy district of Jordanów, in the małopolskie province of southern Poland. It serves a small community of 697 people, reflecting its role in managing domestic wastewater for this part of the region. 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 of this size. With a designed capacity of 3,200 m³/day and an actual discharge volume of 99.38 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into local watercourses that eventually drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant's operation helps protect the local watershed and downstream aquatic ecosystems from untreated pollution.

The plant discharges into the local catchment of the Skawa River, a tributary of the Vistula River. The Vistula flows through Poland and empties into the Baltic Sea. The area is part of the Carpathian foothills, with sensitive aquatic habitats that support diverse fish and invertebrate species. Proper wastewater treatment is essential to prevent nutrient loading and maintain water quality in this ecologically important region.
