Oczyszczalnia sciekow w Kamionce - Secondary Wastewater Treatment Plant in Sadurki, Poland

Oczyszczalnia sciekow w Kamionce is a municipal wastewater treatment plant located in Sadurki, within the gmina Nałęczów, powiat puławski, województwo lubelskie, Poland. The plant serves a small population of 558 residents, reflecting its role in a rural community. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. With a designed capacity of 1700 m³/day, the plant has ample capacity for current loads, operating at a low utilization rate. The treatment process ensures compliance with Polish and EU standards for wastewater treatment in small communities. The treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic life and preventing eutrophication in downstream waters. Its operation contributes to the ecological health of the Lublin region's surface waters.

The plant discharges into local streams that are part of the Vistula River basin, the largest river system in Poland. The Vistula flows into the Baltic Sea, a semi-enclosed sea sensitive to nutrient pollution. The plant's secondary treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication and supporting biodiversity in the river and coastal waters.
