OS Jurkow Wastewater Treatment Plant, Tylmanowa, Poland

OS Jurkow is a municipal wastewater treatment plant located in Tylmanowa, within the małopolskie province of southern Poland. The facility serves a population of approximately 3,018 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. Its designed capacity is 4,400 m³/day, with an average daily discharge volume of 430.32 m³/day, indicating ample reserve capacity. The treated effluent is discharged into a local watercourse that ultimately drains 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 water quality of the Dunajec basin, which supports diverse aquatic life and is used for recreation and agriculture.

The plant discharges into a tributary of the Dunajec River, which flows through the Pieniny Mountains and joins the Vistula River before reaching the Baltic Sea. The Dunajec basin is ecologically sensitive, supporting diverse fish populations and serving as a migratory corridor for aquatic species. Secondary treatment helps reduce organic pollution and nutrient loads, mitigating eutrophication risks in downstream waters.
