Gilbert AZ Water Restrictions 2026

Current water restrictions in Gilbert, Arizona

Gilbert is under Stage 2 Drought Response restrictions, limiting outdoor irrigation to 2 assigned days per week with a mid-day watering blackout in effect until conditions improve.

The Town of Gilbert Water division, operating under the Town of Gilbert (gilbertaz.gov), implemented Stage 2 restrictions in alignment with the broader Phoenix metropolitan area drought response. Gilbert's restrictions track directly with the regional emergency declared across Phoenix metro communities as Colorado River water supplies continue to decline under federally declared shortage conditions.

At the state and federal level, Arizona is operating under a Tier 2 Colorado River Shortage, which triggers mandatory delivery reductions to Central Arizona Project (CAP) allocations. The CAP, which delivers Colorado River water to Gilbert via the 336-mile canal system from Lake Havasu, faces potential allocation cuts of up to 27% under post-2026 federal guidelines — making current conservation measures critical infrastructure policy, not just seasonal precaution.

Gilbert's Stage 2 designation is specifically tied to declining storage levels in Lakes Mead and Powell and the resulting pressure on CAP supply reliability. Because Gilbert depends heavily on CAP water supplemented by Salt River Project (SRP) deliveries and groundwater banking, reduced Colorado River flows directly affect the town's available supply.

Practically, this means a Gilbert resident cannot water their garden on a Wednesday morning unless Wednesday is one of their two assigned watering days. Even on allowed days, watering during mid-day hours is prohibited. A resident watering outside their assigned days — or during the blackout window — is in violation of the current Stage 2 restrictions and subject to escalating penalties. The restrictions apply to all outdoor irrigation: lawn sprinklers, rotary heads, and in-ground systems alike.

Your assigned watering schedule

Under Stage 2, Gilbert assigns watering days based on your property's street address. Odd-numbered addresses are assigned different days than even-numbered addresses, spreading irrigation load across the distribution system and reducing peak demand on Gilbert's water infrastructure. Contact Town of Gilbert Water directly at gilbertaz.gov to confirm the specific days assigned to your address under the current Stage 2 schedule.

Multi-family residential properties and commercial irrigation accounts are subject to the same two-day restriction, but large commercial and HOA-managed irrigation systems may coordinate a customized compliance schedule with Town of Gilbert Water for metered accounts drawing significant volume. Commercial properties with recycled water irrigation connections have separate guidelines — confirm your meter type before assuming your system is automatically exempt.

Gilbert's desert climate means landscape trees demand priority attention on your two allowed days. Blue Palo Verde (Parkinsonia florida), the iconic Arizona state tree found throughout Gilbert neighborhoods, benefits most from deep, infrequent watering — exactly what a twice-weekly deep soak provides. Established Desert Willow (Chilopsis linearis) and Velvet Mesquite (Prosopis velutina) are both common in Gilbert landscaping and, while drought-adapted, will show stress and canopy dieback during extended Stage 2 conditions without targeted deep watering at their drip lines during your two allowed days.

Fines and penalties

Town of Gilbert Water enforces Stage 2 restrictions through a combination of methods. Gilbert has deployed advanced metering infrastructure (AMI) — smart meters across its service territory that provide near-real-time consumption data. Unusual usage patterns during blackout hours or on non-assigned days can flag an account without a physical inspection. Field patrols by Gilbert's Water Conservation team also respond to reports, particularly in residential neighborhoods where sprinkler runoff is visible from the street. Neighbor complaints submitted through the Town's online portal are logged and typically receive a field response within 3–5 business days.

If you receive a violation notice you believe was issued in error — for example, your drip irrigation ran during blackout hours due to a controller malfunction — Gilbert allows an administrative appeal to the Water Conservation Division. Document the equipment failure, submit a repair receipt, and request appeal review in writing within the deadline stated on your notice. First-offense warnings are generally resolved without escalation when the property owner demonstrates corrective action promptly.

Other outdoor water rules

Beyond lawn irrigation, Stage 2 restrictions in Gilbert address several other outdoor water uses. Given Gilbert's climate — summer temperatures regularly exceeding 110°F — pool evaporation and car washing represent the two highest-volume discretionary outdoor uses after landscape irrigation.

• Swimming pools: Topping off pool water lost to evaporation is permitted but must use a shut-off valve and avoid mid-day hours. New pool fills require a permit and pre-authorization from Town of Gilbert Water under Stage 2.
• Car washing: Residential vehicle washing is restricted to two days per week matching your assigned irrigation days, and must use a hose with an automatic shut-off nozzle. Commercial car washes with recirculating systems are exempt.
• Decorative fountains and water features: Recirculating fountains are permitted. Single-pass or non-recirculating decorative water features must be shut off during Stage 2.
• Pressure washing: Permitted for health and safety purposes (mold removal, food service areas) only. Aesthetic or routine surface cleaning by hose or pressure washer is prohibited.
• Construction water: Dust control and concrete curing are exempt with active permits. Non-essential construction site irrigation is restricted and requires documentation of necessity submitted to the Town.
• Restaurants and commercial dining: Serving water only upon request is required at all Gilbert food service establishments under Stage 2 — this is a codified restriction, not a suggestion.

Gilbert's water supply and source

Gilbert draws its water from three primary sources, each of which is under stress during the current Tier 2 Colorado River Shortage.

The largest share of Gilbert's supply comes from the Central Arizona Project (CAP), the 336-mile aqueduct that pumps Colorado River water from Lake Havasu on the Arizona-California border. CAP water arrives at the Greenfield Water Campus and is treated before entering Gilbert's distribution system. Under current Tier 2 Shortage conditions, Arizona's CAP allocation is reduced, and further cuts under post-2026 federal guidelines could reduce deliveries by up to 27% — a direct threat to Gilbert's primary supply.

Gilbert also receives treated water from the Salt River Project (SRP), which stores and delivers water from the Salt and Verde Rivers via a system of reservoirs including Roosevelt Lake, Saguaro Lake, and Bartlett Reservoir. SRP surface water storage is the historic backbone of the Phoenix metro's supply, but prolonged drought has reduced inflow to these reservoirs significantly over the past decade.

Groundwater from the East Valley aquifer system serves as Gilbert's third source and as a drought buffer. Gilbert participates in the Arizona Water Bank Authority's underground storage and recovery program, artificially recharging the aquifer during high-delivery years to maintain banked reserves. The town operates groundwater recovery wells at multiple sites within its service territory. Reclaimed water — treated effluent distributed through a separate purple-pipe system — irrigates parks, golf courses, and some commercial properties, reducing potable demand. Gilbert treats reclaimed water at its Greenfield Water Reclamation Facility.

HOA rules during water restrictions

Arizona Revised Statutes § 33-1817 prohibits HOAs from fining homeowners for allowing their landscaping to go dormant or brown during a declared water shortage or government-mandated watering restriction. Under current Stage 2 Drought Response conditions in Gilbert, your HOA cannot legally penalize you for a brown or stressed lawn that results from complying with Town of Gilbert Water's two-day watering limit.

ARS § 33-1817 applies to planned communities governed by CC&Rs and to condominium associations under ARS § 33-1253. If your HOA issues a violation notice for dead or dormant turf while Stage 2 restrictions are in effect, the notice is legally unenforceable. Document the Town's restriction status — print or screenshot the current restriction notice from gilbertaz.gov — and include it with your response. The HOA is not permitted to proceed to fines while a government water restriction order is active.

Use this template to respond to an HOA violation notice:

"This notice is issued in error under Arizona law. My property is located within the Town of Gilbert Water service area, which is currently operating under a Stage 2 Drought Response restriction limiting outdoor irrigation to two assigned days per week. Per Arizona Revised Statutes § 33-1817, no HOA may fine a member for landscape dormancy or browning that results from compliance with a government-mandated water restriction. I am in full compliance with Town of Gilbert Water's current Stage 2 requirements. I request this violation notice be withdrawn immediately. Copies of the applicable restriction order and state statute are attached."

Lawn survival guide for Gilbert

In Gilbert's desert climate — averaging fewer than 8 inches of annual rainfall and summer soil temperatures that can exceed 130°F at the surface — the most practical Stage 2 strategy for turf areas is to shift away from high-water cool-season overseed cycles and maintain native or warm-season grasses in deep dormancy. Bermudagrass, the dominant residential turf in Gilbert, survives extended drought by going brown and dormant rather than dying. Raise your mow height to 1.5–2 inches to shade soil and reduce evapotranspiration. Water deeply on your two allowed days rather than lightly each day — deep watering encourages deeper root penetration and significantly extends the interval the grass can survive without irrigation.

Stage 2 is an appropriate trigger to seriously evaluate xeriscape conversion through Gilbert's Water Conservation rebate programs. Replacing Bermuda turf with decomposed granite, native desert plantings — Saguaro, Brittlebush, Lantana, and Desert Marigold are all proven Gilbert-climate performers — eliminates turf irrigation demand entirely. Gilbert's Water Conservation Rebate Program offers per-square-foot rebates for qualifying turf removal projects. Converting even a portion of your front turf to xeriscape before the next watering season substantially reduces your two-day restriction burden and positions your landscape for long-term viability as CAP allocations tighten post-2026.

Frequently asked questions

What are my two assigned watering days under Gilbert's Stage 2 restrictions?

Your assigned watering days are based on your street address — odd-numbered addresses and even-numbered addresses are assigned different day pairs to distribute load across Gilbert's water system. To confirm the exact days tied to your specific address under the current Stage 2 schedule, contact Town of Gilbert Water directly through gilbertaz.gov. Do not assume your days match a neighbor's; addresses on opposite sides of the same street may have different assignments.

Can I water at any time on my two allowed days?

No. Even on your assigned watering days, irrigation during the mid-day blackout window — 10:00 a.m. to 6:00 p.m. — is prohibited. You must complete or begin irrigation before 10:00 a.m. or wait until after 6:00 p.m. This blackout applies to in-ground sprinkler systems and rotary heads. Drip irrigation is generally exempt from day restrictions but is still subject to the mid-day hour blackout under Stage 2.

Does Town of Gilbert Water use smart meters to catch violations?

Yes. Gilbert has deployed advanced metering infrastructure (AMI) across its residential and commercial service territory. These smart meters transmit near-real-time usage data, which the Water Conservation Division can analyze to flag accounts showing irrigation activity during blackout hours or on non-assigned days — without a physical site visit. If your irrigation controller malfunctions and runs during prohibited hours, your meter will log it. Fix controller issues proactively and document repairs in case you need to appeal a violation notice.

What rebates does Gilbert offer for removing my grass?

Town of Gilbert Water operates a Water Conservation Rebate Program that includes per-square-foot incentives for removing qualifying irrigated turf and replacing it with desert-adapted landscaping or decomposed granite. Rebate amounts and program availability shift based on funding cycles. Submit your rebate application and receive pre-approval before beginning removal — retrofits completed without prior approval are typically ineligible. Visit gilbertaz.gov and search "water conservation rebates" for the current per-square-foot rate and program requirements.

Can I wash my car at home during Stage 2?

Residential car washing is permitted only on your two assigned irrigation days, and you must use a hose equipped with an automatic shut-off nozzle — a hose left running unattended is a violation. Bucket washing is always allowed. Commercial car washes with fully recirculating water systems are exempt from the day restriction. If you use a drive-through commercial wash, there is no restriction on frequency.

Is my drip irrigation system subject to the two-day restriction?

Drip irrigation — low-flow emitters delivering water directly to root zones — is exempt from the two-days-per-week restriction under Gilbert's Stage 2 rules. However, drip systems are not exempt from the mid-day blackout hours (10:00 a.m.–6:00 p.m.). Program your drip controller to run before 10:00 a.m. or after 6:00 p.m. to remain in full compliance. Check that your system is actually classified as drip — micro-spray heads that project water into the air may be treated differently than true point-emitter drip systems.

How does the CAP Tier 2 Shortage affect how long Stage 2 restrictions will last in Gilbert?

Gilbert's Stage 2 restrictions remain in effect "until conditions improve" — there is no fixed end date. The primary trigger for potential downgrade would be recovery in Colorado River storage levels at Lake Mead and Lake Powell, which determine CAP allocation tiers under the 2019 Drought Contingency Plan and federal Interim Guidelines. Under current Bureau of Reclamation projections, Tier 2 conditions are likely to persist through at least the near term, and post-2026 operating guidelines under negotiation may reset the baseline. Gilbert will announce any change in restriction phase through its official communications at gilbertaz.gov.

My HOA sent me a violation notice for a brown lawn — do I have to pay it?

No. Arizona Revised Statutes § 33-1817 explicitly prohibits HOAs from fining members for landscape dormancy caused by compliance with a government-mandated water restriction. Gilbert's Stage 2 Drought Response is an active government order issued by Town of Gilbert Water. Print the current Stage 2 restriction notice from gilbertaz.gov, attach a copy of ARS § 33-1817, and send written notice to your HOA that the fine is legally unenforceable while the restriction order is active. If the HOA pursues the fine regardless, contact the Arizona Department of Real Estate or consult a licensed Arizona attorney familiar with planned community law.
