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.
Phoenix FAQ
When can I water my Phoenix lawn?
Under Stage 1 voluntary, no specific day or hour restriction applies, but watering early morning is recommended to reduce evaporation. Stage 2 introduces odd/even watering; Stage 3 sets specific hours and bans new turf.
Is water-wise landscaping required?
Not for existing properties. New Phoenix developments must meet the Phoenix Plant List for low-water-use species in common areas and limit high-water-use turf. The Phoenix Water Services rebate program incentivizes voluntary turf removal.
How much water does Phoenix use per person?
Phoenix's gallons per capita per day fell to about 165 GPCD in 2023, well below the 200+ GPCD of the 1990s, due to plumbing-fixture rules, leak repair, smart meters, and rising tier pricing through Phoenix Water Services.
