Pulanki Wastewater Treatment Plant, Wołowiec, Poland

Pulanki wastewater treatment plant is located in Wołowiec, within the gmina Sękowa of powiat gorlicki, in the małopolskie province of Poland. The plant serves a population of approximately 1,606 people, classifying it as a small agglomeration under Polish and EU regulations. 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. With a designed capacity of 12,000 m³/day and a current discharge volume of 228.99 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Wisłoka River, a tributary of the Vistula River. The Vistula flows into the Baltic Sea, making the plant's performance important for the ecological health of the Baltic Sea basin. The region is characterized by its Carpathian foothill terrain and rural landscape.

The plant discharges into the Wisłoka River catchment, which flows into the Vistula River and eventually the Baltic Sea. The Baltic Sea is a sensitive ecosystem with eutrophication concerns, making nutrient removal important. The surrounding area includes forested hills and agricultural land, contributing to diffuse pollution risks. The plant's secondary treatment helps reduce organic load but may not fully address nutrient removal required for sensitive areas.
