Mordarka Wastewater Treatment Plant, Falsztyn, Lesser Poland Voivodeship

Mordarka is a wastewater treatment plant located in Falsztyn, a village in the Lesser Poland Voivodeship (województwo małopolskie), southern Poland. The plant serves a population of 1,612 and is part of the municipal infrastructure for the gmina Łapsze Niżne in the Nowy Targ County. The facility provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 15,000. The plant has a designed capacity of 2,000 m³/day and currently discharges an average of 229.85 m³/day, indicating it operates well below its capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Dunajec River, a tributary of the Vistula River. The Vistula flows northward through Poland and empties into the Baltic Sea. The plant plays a key role in protecting the Dunajec River and the broader Vistula basin from untreated wastewater, supporting aquatic life and downstream water quality.

The Mordarka plant discharges into the Dunajec River catchment, which flows into the Vistula River and eventually reaches the Baltic Sea. The Dunajec is a significant river in the Carpathian region, supporting diverse aquatic ecosystems and serving as a migratory corridor for fish. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting the sensitive freshwater habitats in the Pieniny Mountains area downstream.
