Koszyce Wlostowice Wastewater Treatment Plant - Włostowice, Poland

Koszyce Wlostowice is a municipal wastewater treatment plant located in Włostowice, a village in the małopolskie province of southern Poland. The facility serves a population of 923, classifying it as a small agglomeration under EU regulations. The plant is situated in a rural area within the Vistula River basin. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 7000 cubic meters per day, with a current discharge volume of 131.61 cubic meters per day, indicating significant spare capacity. Treated effluent is discharged into local watercourses that ultimately drain into the Vistula River, Poland's longest river, which flows into the Baltic Sea. The plant plays a role in protecting the Vistula basin from nutrient pollution, supporting aquatic life and downstream ecosystems in the Baltic Sea region.

The plant discharges into the Vistula River basin, which flows northward through Poland to the Baltic Sea. The Vistula supports diverse aquatic habitats and is an important migratory corridor for fish species. The Baltic Sea is sensitive to nutrient loading, making secondary treatment essential for reducing eutrophication risks in coastal waters.
