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.
Surprise 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.
