The treated effluent from the plant is discharged into local water bodies that eventually drain into the Po River basin and the Adriatic Sea. The surrounding watershed supports diverse aquatic life and agricultural activities, making effective wastewater treatment essential for maintaining water quality and ecosystem health in the region.

The plant discharges into the local drainage network, which flows into the Po River basin and ultimately reaches the Adriatic Sea. This watershed supports a mix of agricultural and urban areas, and the receiving waters are ecologically sensitive, providing habitat for fish and other aquatic organisms. Proper treatment helps prevent nutrient enrichment and contamination downstream.
