Moszczenica Wastewater Treatment Plant, Podegrodzie, Poland

Moszczenica is a wastewater treatment plant located in Podegrodzie, a village in the Lesser Poland Voivodeship of southern Poland. The plant serves a population of 3,183, classifying it as a small agglomeration under Polish regulations. It is situated in a rural, inland area away from the coast. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 3,500 m³/day, with an average daily discharge of 453.85 m³/day, indicating operational capacity well below design limits. The treated effluent is discharged into local waterways that ultimately drain into the Dunajec River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution.

The plant discharges into the Dunajec River basin, part of the Vistula River system that flows into the Baltic Sea. The Dunajec supports diverse aquatic life and is an important recreational river in the region. The plant's secondary treatment helps reduce organic load and nutrients, protecting downstream water quality in the Vistula and Baltic Sea.
