Kamien Wastewater Treatment Plant, Kamień, Lublin Voivodeship, Poland

The Kamien wastewater treatment plant is located in Kamień, a village in the Lublin Voivodeship of eastern Poland. This facility serves a small population of 592 residents, reflecting its role in a rural community. The plant is part of Poland's municipal wastewater infrastructure, which operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard biological treatment required for all agglomerations under the EU directive. It has a designed capacity of 2750 m³/day, though current discharge volume is 84.41 m³/day, indicating significant spare capacity. Secondary treatment typically involves biological oxidation and settling. The treated effluent is discharged into local watercourses, likely tributaries of the Wieprz River or the Bug River, which flow into the Vistula River and eventually the Baltic Sea. The plant helps protect the region's surface waters from nutrient pollution, supporting aquatic ecosystems in the Lublin region's agricultural landscape.

The plant discharges into local streams that drain into the Wieprz River basin, a tributary of the Vistula River. The Vistula flows north to the Baltic Sea, making the plant part of a larger watershed that supports diverse aquatic life. The region is predominantly agricultural, so the plant's nutrient removal helps mitigate eutrophication risks in downstream water bodies.
