Gilbert FAQ
Are there odd-even watering days in unincorporated areas?
No. Maricopa County has not adopted day-of-week watering rules. Cities like Scottsdale and Mesa run their own programs; well-served unincorporated parcels follow ADWR conservation programs through the Phoenix AMA.
Do I need a permit for a private well?
Wells producing under thirty-five gallons per minute are exempt but must be registered with ADWR. Larger wells need a Type-1 or Type-2 grandfathered groundwater right or a service-area right under ARS title 45.
Mesa FAQ
Is there a watering day schedule?
Mesa does not assign odd/even watering days like some Phoenix metro cities. Instead it limits the hours of day during peak summer months and prohibits waste through overspray rules.
What is Tier shortage?
The federal Bureau of Reclamation declared shortage tiers on the Colorado River that reduce CAP deliveries to Arizona. Mesa absorbs cuts through conservation and SRP balancing rather than rationing.
