The plant helps protect local water quality and supports the ecological health of the surrounding arid landscape.

The plant discharges into the Sonora River basin, which flows through the state of Sonora and empties into the Gulf of California. This region is characterized by arid conditions and supports a variety of desert-adapted wildlife. Proper wastewater treatment is essential to prevent contamination of groundwater and surface waters that sustain local agriculture and ecosystems.
