Reclaimed Water Rulemaking

ADEQ is revising Arizona’s rules governing the reuse of reclaimed water and gray water. Since these rules were last updated in 2001, Arizona has experienced an expansion in the beneficial reuse of treated wastewater, including new research, technology and proposed uses of reclaimed water.

Reclaimed water is highly treated wastewater from a wastewater treatment plant (Arizona Revised Statutes § 49-201(32)). Reclaimed water has uses, such as irrigation, that offset and conserve potable water for human consumption and domestic purposes. Gray water is wastewater that has been collected separately from a sewage flow and that originates from a clothes washer or a bathroom tub, shower or sink but that does not include wastewater from a kitchen sink, dishwasher or toilet (Arizona Revised Statutes § 49-201(18)). Gray water also has uses, such as landscape irrigation, that augment Arizona’s water supply.

ADEQ conducted three listening sessions to gather stakeholder input on possible key changes to the rules and developed a stakeholder issue matrix to summarize the stakeholder input | View Matrix >

ADEQ has also requested two expert workgroups to assist in providing technical advice regarding reclaimed standards, and infrastructure and technology. ADEQ expects the workgroups to provide their recommendations by the end of October 2017. ADEQ will then review the rules in light of that technical advice, additional stakeholder input, and internal expertise.
