Overview
Łęki wastewater treatment plant in województwo małopolskie, Poland, serves 2,564 people with advanced treatment. It discharges 365.59 m³/day of treated wastewater, with a designed capacity of 5,227 m³/day.
The Łęki wastewater treatment plant is located in the village of Łęki, within gmina Kęty, powiat oświęcimski, in the małopolskie voivodeship of southern Poland. This facility serves a population of 2,564, classifying it as a small agglomeration under Polish and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 5,227 m³/day indicates significant reserve capacity relative to the current discharge volume of 365.59 m³/day, suggesting the plant can accommodate future growth. The treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the region, including the Vistula's tributaries and the Baltic Sea coastal environment.
Environmental context
The plant discharges into the Vistula River basin, which drains into the Baltic Sea. The region is part of the Carpathian foothills, with rivers supporting diverse aquatic life and serving as important migratory corridors. Advanced treatment reduces nutrient loads, helping to mitigate eutrophication in the Baltic Sea, a sensitive marine environment.
