The plant supports the health of the Gila River watershed, which ultimately drains into the Colorado River and the Gulf of California.

The plant discharges into the Salt River basin, a tributary of the Gila River, which flows into the Colorado River and eventually reaches the Gulf of California. The arid Southwest relies on reclaimed water to maintain base flows in rivers and support riparian habitats. The facility helps protect downstream water quality in a region where water scarcity and ecosystem preservation are critical concerns.
