Rozaniec Pierwszy Wastewater Treatment Plant, Różaniec Pierwszy, Poland

Rozaniec Pierwszy is a wastewater treatment plant located in the village of Różaniec Pierwszy, within the gmina Tarnogród, powiat biłgorajski, województwo lubelskie, Poland. The plant serves a very small population of 5 people, reflecting its role in a rural community. As a secondary treatment facility, it meets the basic standards for organic matter and suspended solids removal required under Polish regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 2276 cubic meters per day, indicating infrastructure sized for potential future growth or seasonal variations. Under the EU directive, agglomerations of this size are subject to appropriate treatment requirements, though the plant's current discharge volume of 0.71 cubic meters per day is minimal. The treated effluent is discharged into local watercourses that eventually drain into the Tanew River, a tributary of the San River, which flows into the Vistula River and ultimately the Baltic Sea. This small plant plays a role in protecting local groundwater and surface water quality in the Lublin region, an area characterized by agricultural land use and scattered settlements.

The plant discharges into local streams that feed into the Tanew River, a right-bank tributary of the San River. The San River flows into the Vistula, which empties into the Baltic Sea via the Gulf of Gdańsk. The surrounding watershed in województwo lubelskie includes sensitive aquatic habitats that support diverse fish and macroinvertebrate communities. The region's agricultural runoff can contribute nutrient loads, making the plant's secondary treatment important for reducing organic pollution in these small watercourses.
