WateReuse California Conference 2023

Direct Potable Reuse (DPR) is gaining momentum as a sustainable water supply management strategy. Colorado recently completed DPR rulemaking, while California, Arizona, and Florida are currently in the process. Arizona has a longstanding history of water reuse, with legislative authority granted to the Arizona Department of Environmental Quality (ADEQ) to protect water quality and human health. ADEQ is currently revising Arizona's reclaimed water rules. Indirect potable reuse (IPR) is not regulated in Arizona, but it can be conducted under separate ADEQ groundwater protection permitting regulations. Apart from graywater use, there are no specific rules in Arizona for onsite or decentralized water reuse.
