Arizona moves a step closer to direct potable reuse

Published February 8th, 2018

A new framework document published by the National Water Research Institute (NWRI) contains a series of recommendations for the development of regulations for direct potable reuse (DPR) in Arizona.

The widespread beneficial reuse of treated wastewater in the state is currently hampered by the formal prohibition of DPR under the Arizona Administrative Code, making it in some ways the laggard among the other key states which are actively investigating DPR (California, Texas, New Mexico and Florida).

The Arizona State Department of Environmental Quality is now working on a new regulation which would specifically remove this handicap.

“Based on current information and experience, it is feasible for the State of Arizona to develop regulations for DPR that would incorporate a level of public health protection as good as or better than what is provided currently by conventional drinking water supplies in the United States,” according to the NWRI’s new framework document.
