Polany Wastewater Treatment Plant, małopolskie, Poland

Polany wastewater treatment plant is located in the village of Polany, gmina Krynica-Zdrój, in the małopolskie province of southern Poland. The plant serves a small population of 751 residents, reflecting its role in a rural community within the scenic Beskid Sądecki mountain region. The facility employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 2000 population equivalent. The plant's designed capacity of 2300 m³/day indicates it can handle peak flows, while the current discharge volume of 107.08 m³/day suggests ample reserve capacity. The treated effluent is discharged into local watercourses that eventually drain into the Poprad River, a tributary of the Dunajec, which flows into the Vistula and ultimately the Baltic Sea. The plant's advanced treatment helps protect the sensitive mountain streams and downstream aquatic ecosystems from nutrient pollution.

The plant discharges into small streams in the Poprad River basin, which flows through the Carpathian foothills into the Dunajec River. The Dunajec joins the Vistula, which empties into the Baltic Sea. The local watershed supports diverse aquatic life, including brown trout and other cold-water species, and is part of an ecologically sensitive mountain region. Advanced treatment ensures minimal impact on these vulnerable water bodies.
