Mesa operates two water reclamation plants and distributes Class A+ reclaimed water for golf courses, parks, and select industrial users. Recycled water reduces strain on potable supplies from SRP and CAP.
Mesa's Northwest and Southeast Water Reclamation Plants treat municipal wastewater to ADEQ Class A+ standards, allowing reuse for irrigation of public parks, golf courses, and industrial cooling. A purple-pipe distribution network serves committed customers. Cross-connection rules enforced under the Mesa Plumbing Code and ARS Title 49 prohibit any tie-in between potable and reclaimed lines. Residential direct potable reuse is not currently practiced in Mesa, though indirect benefits accrue through reduced demand on the SRP/CAP system.
Cross-connections between potable and reclaimed lines trigger immediate service shutoff and ADEQ reportable events; backflow incidents face state and city penalties.
