Ruda Rozaniecka Wastewater Treatment Plant - Ruda Różaniecka, Poland

Ruda Rozaniecka wastewater treatment plant is located in the village of Ruda Różaniecka, within the Podkarpackie Voivodeship of southeastern Poland. The facility serves a population of 1,329, 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 inland agglomerations of this size. With a designed capacity of 2,340 m³/day and an actual discharge volume of 189.50 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local waterways that eventually drain into the San River basin, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting the region's water quality and supporting the ecological health of the downstream environment.

The plant's discharge enters small streams in the Lubaczówka River catchment, part of the San River basin. The San River flows into the Vistula, Poland's largest river, which empties into the Baltic Sea. The region supports diverse aquatic life, including fish species such as barbel and chub, and the plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the Baltic.
