Wola Debinska Wastewater Treatment Plant - Wola Dębińska, Lesser Poland

The Wola Debinska wastewater treatment plant is located in Wola Dębińska, a village in the Lesser Poland Voivodeship (województwo małopolskie), southern Poland. The plant serves a population of 2,043 and operates under Polish regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the minimum required under the EU directive for agglomerations of this size (2,000-10,000 population equivalent). Its designed capacity is 5,913 m³/day, and the current discharge volume is 291.30 m³/day, indicating significant spare capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows north to the Baltic Sea. The plant plays a key role in protecting the region's surface waters from untreated sewage, supporting aquatic life and downstream water quality.

The plant discharges into small streams that feed into the Dunajec River, a tributary of the Vistula. The Vistula flows through central Poland to the Baltic Sea. The local watershed supports diverse aquatic habitats and is part of a region known for its agricultural and natural landscapes. Proper treatment helps prevent nutrient pollution that could lead to eutrophication in downstream waters.
