Oczyszczalnia Komunalna w Naleczowie - Advanced Wastewater Treatment in Nałęczów, Poland

Oczyszczalnia Komunalna w Naleczowie is a municipal wastewater treatment plant located in Nałęczów, in the Lublin Voivodeship of eastern Poland. The plant serves a population of approximately 6,905 residents, placing it in the small-to-medium agglomeration category under Polish and EU regulations. The facility employs advanced treatment processes, which go beyond the EU Urban Waste Water Treatment Directive's minimum requirement of secondary treatment for agglomerations of this size. With a designed capacity of 14,150 m³/day and a current discharge volume of 984.55 m³/day, the plant has significant reserve capacity to accommodate future growth or seasonal fluctuations. The treated effluent is discharged into local waterways that eventually drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the region's water quality, particularly the sensitive ecosystems of the Vistula River and its tributaries, which support diverse aquatic life and are important for both ecological balance and human use.

The plant discharges into the Vistula River basin, which flows through eastern Poland and empties into the Baltic Sea. The Vistula is the longest river in Poland and supports a wide range of aquatic species, including migratory fish. The advanced treatment helps reduce nutrient loading, protecting downstream water bodies from eutrophication and maintaining ecological health in the Baltic Sea region.
