Overview
Piwniczna-Zdrój wastewater treatment plant serves the spa town in southern Poland's Lesser Poland Voivodeship. The secondary treatment facility handles a designed capacity of 10,300 m³/day, protecting local water quality in the Poprad River basin.
The Piwniczna-Zdrój wastewater treatment plant is located in the spa town of Piwniczna-Zdrój, within the Lesser Poland Voivodeship (województwo małopolskie) in southern Poland. The facility serves a population of approximately 2,923 residents and is part of the municipal infrastructure supporting this popular health resort destination in the Poprad River valley. The plant provides secondary treatment, which is the standard biological treatment stage required under Polish regulations aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations under 10,000 population equivalent, secondary treatment is the baseline requirement. The plant has a designed capacity of 10,300 m³/day, indicating it is sized to accommodate seasonal population fluctuations typical of a tourist destination. The treated effluent is discharged into the local water system, ultimately reaching the Poprad River, a tributary of the Dunajec River, which flows into the Vistula and then to the Baltic Sea. The plant plays a key role in preserving the water quality of the Poprad River, which supports aquatic life and is important for the region's tourism and natural environment.
Environmental context
The plant discharges into the Poprad River catchment, part of the upper Vistula basin that drains to the Baltic Sea. The Poprad River is a Carpathian stream supporting diverse aquatic ecosystems, including fish species such as brown trout and grayling. The region's mountainous terrain and spa character make water quality protection critical for both ecological health and tourism.
