A brief description of the source of non-potable water and how it is used:
There is a water capture project program at the Arizona State University Tempe campus Central Plant. The project captures previously wasted reverse osmosis reject water for reuse on mall power-washing and central plant cooling tower chillers. Over 4,000,000 gallons of water are saved annually by re-using the Reverse Osmosis reject water.
The Barrett Honors College Complex includes a greywater treatment and reuse system for buildings 7A and 7B. Greywater from building sinks, water fountains, and showers is treated to a reuse standard that is suitable as a water closet supply and/or an irrigation supply. The Greywater design flow is 10,000 gallons per day.
The Biodesign Institute includes a Graywater Capture Project - The Biodesign Institute has realized a 50% reduction in landscape water use from the installation of a high efficiency drip irrigation system that is supplied by greywater captured on-site.
