Since 1998, Tucson Water has retooled how we treat and deliver our Colorado River water supply, expanded our uses of reclaimed water, brought rain/stormwater into the water supply mix, and reduced our potable water use down to mid-1980s levels through conservation. These collective actions have reduced our reliance on groundwater, which now serves as only one part of a robust and diverse water supply portfolio. As a result, the status of our aquifer is vastly improved and Tucson’s water future is sound.
