Phoenix AZ Water Restrictions 2026

Current water restrictions in Phoenix, Arizona

Phoenix is under Stage 2 Drought Response restrictions, limiting outdoor watering to 2 assigned days per week with a mid-day blackout window enforced citywide.

Phoenix Water Services declared Stage 2 Drought Response as Salt River Project (SRP) combined reservoir storage dropped to 52% — below the 60% threshold that would allow a return to Stage 1. Simultaneously, Lake Mead fell into a federal Tier 2 Shortage designation, cutting Arizona's Colorado River allocation and squeezing the Central Arizona Project (CAP) supply that feeds roughly half of Phoenix's water portfolio. The two shortages arriving together — local SRP storage and federal Colorado River reductions — are what pushed Phoenix into Stage 2 rather than the less restrictive Stage 1 level.

The precipitation picture made the trigger inevitable. Phoenix recorded only 2.1 inches of rainfall between October 2025 and April 2026, against a seasonal normal of 6.4 inches. That deficit left SRP's reservoir system — including Roosevelt Lake, Saguaro Lake, and Canyon Lake on the Salt and Verde rivers — with no meaningful natural recharge during the wet season.

At the state level, Arizona is operating under a Colorado River Tier 2 Shortage, and the Central Arizona Project is warning of potential 27% allocation cuts under post-2026 federal shortage-sharing guidelines. Tucson and other metro Phoenix municipalities face comparable restrictions.

Practically, a resident cannot simply water on a Wednesday morning whenever they feel like it. Under Stage 2, you water only on your two assigned days, and watering during mid-day hours is prohibited regardless of day. If your assigned days happen to be Tuesday and Friday, you cannot water on Wednesday morning — not even briefly. Violating the schedule on the first documented offense draws a warning; the second offense triggers a $250 fine. Contact Phoenix Water Services at phoenix.gov/water or 602-262-6251 to confirm your assigned watering days.

Phoenix's watering days and hours

Phoenix Water Services assigns watering days by street address number. Properties with odd-numbered addresses water on one pair of designated days; even-numbered addresses water on the alternate pair. Your exact day pair depends on which utility zone your account falls within — log in to your Phoenix Water account at phoenix.gov/water or call 602-262-6251 to pull up your specific assignment. Do not assume your schedule based on a neighbor's; zone boundaries do not always follow block lines.

Multi-family residential properties — apartments, condominiums, and townhome complexes — are treated as a single account and must comply with the two-day limit across all shared landscaping. Property managers are responsible for programming community irrigation controllers and are subject to the same fine schedule as single-family accounts. Commercial properties face the same day restrictions but a steeper fine structure, with egregious violations reaching $2,500 per incident.

Phoenix's urban tree canopy requires special attention during Stage 2. Velvet mesquite, blue palo verde, and desert willow — three of the most common street and yard trees in the metro — are drought-adapted but still need deep watering every 10–21 days during summer heat. Under current rules, deep-watering these trees with a slow drip or soaker on one of your two assigned days counts toward your weekly allocation. A slow overnight drip system applied at the drip line qualifies as drip irrigation and is exempt from the day restriction, making it the most practical approach for established trees during Stage 2.

Note that cool-season overseed is explicitly prohibited under Stage 2 rules. Homeowners who would normally overseed dormant Bermuda lawns with ryegrass in October or November must skip this cycle for the current restriction period.

Violation fines and enforcement

Phoenix Water Services enforces Stage 2 restrictions through a combination of automated smart meter alerts, field patrol crews, and resident complaints submitted through the city's online portal. The city's Advanced Metering Infrastructure (AMI) network can flag accounts showing water flow during prohibited mid-day hours or usage patterns inconsistent with a two-day schedule — inspectors then follow up with a site visit. Complaint-based reports submitted online are typically investigated within 5–7 business days, and the city does not reveal the identity of complainants to the property owner.

If you receive a violation notice and believe it was issued in error — for example, a drip system was misidentified as spray irrigation — Phoenix Water Services has a formal appeals process. Submit a written appeal to the Water Services Department within 15 days of the notice date, including your account number, the violation date, and any documentation (photos, irrigation controller logs, drip system invoices). Appeals are reviewed by a Water Services supervisor, not the original issuing officer. First-time warning notices are not fined but are retained in your account history; a second violation on the same property within 12 months automatically escalates to the $250 fine level regardless of whether different occupants are involved.

Other outdoor water rules

Beyond lawn irrigation, Stage 2 Drought Response in Phoenix restricts or modifies several other outdoor water uses. Pool evaporation is a significant concern given Phoenix's 110°F+ summer temperatures, so pool rules are among the most closely watched.

• Swimming pools: New pool filling requires a permit and is restricted to off-peak hours. Topping off an existing pool to offset evaporation is permitted but must use a shut-off device; leaving a fill hose running unattended is prohibited. Pool covers are strongly encouraged — Phoenix Water Services estimates covers reduce evaporation by up to 30% in summer conditions.
• Car washing: Residential car washing is permitted only with a hand-held hose equipped with a self-closing nozzle. Running water continuously from a hose without a shut-off nozzle is prohibited under Stage 2. Commercial car washes must use water recycling systems; those without recirculating equipment are subject to operational restrictions.
• Pressure washing: Pressure washing of driveways, sidewalks, and exterior walls is prohibited except where required for health or safety reasons (e.g., removing biohazard contamination or preparing a surface for code-required repair). Decorative or routine cleaning does not qualify.
• Ornamental fountains: Recirculating fountains that do not discharge water are permitted. Decorative water features with continuous municipal water supply and no recirculation are prohibited.
• Restaurants and businesses: Water service to customers must be on request only — no automatic table service of water glasses. This rule applies to all food-service establishments holding a City of Phoenix business license.
• Construction water: Dust suppression on active construction sites using potable water requires an approved Water Conservation Plan filed with Phoenix Development Services. Reclaimed water must be used for dust control where a reclaimed water line is available within 1,000 feet of the site.

How Phoenix gets its water

Phoenix draws from three primary water sources: the Salt River Project reservoir system, the Central Arizona Project, and groundwater from the Phoenix Active Management Area (AMA). No single source alone could supply the city; the current shortage stems from simultaneous stress on all three.

The Salt River Project operates six reservoirs on the Salt and Verde rivers east of Phoenix — Roosevelt Lake (the largest, with a 1.65 million acre-foot capacity), Apache Lake, Canyon Lake, Saguaro Lake on the Salt River, and Horseshoe and Bartlett lakes on the Verde River. SRP water reaches Phoenix through the Hayden-Rhodes Aqueduct system and is treated at the Val Vista Water Treatment Plant in Mesa before distribution. Combined SRP storage is currently at 52%, triggering the Stage 2 threshold.

The Central Arizona Project delivers Colorado River water from Lake Havasu through a 336-mile aqueduct to the Phoenix area, terminating at the Granite Reef Diversion Dam. CAP water is treated at the Squaw Peak Water Treatment Plant and the Union Hills Water Treatment Plant before entering Phoenix's distribution system. Under the current federal Tier 2 Shortage declaration, Arizona's CAP allocation has already been reduced, with further cuts possible under post-2026 Drought Contingency Plan guidelines — the city estimates a potential 27% reduction in CAP deliveries in that scenario.

Groundwater from the Phoenix AMA — managed under Arizona's 1980 Groundwater Management Act — serves as a backup and banking source. Phoenix has deposited significant water credits in underground storage facilities (USFs) near the Agua Fria River through the Arizona Water Banking Authority. These stored credits are available for recovery but drawing on them during Stage 2 reduces the long-term buffer the city built over two decades of intentional recharge. The three-source dependency is what makes simultaneous SRP and Colorado River shortages so acute: Phoenix cannot simply lean harder on groundwater without compromising its 100-year assured water supply designation.

HOA and brown lawn protections

Arizona homeowners are protected from HOA enforcement actions related to dormant or brown lawns during declared drought restrictions under Arizona Revised Statutes § 33-1817. This statute prohibits a homeowners association from fining, penalizing, or threatening legal action against a member whose landscaping has died, turned brown, or become visually non-compliant as a direct result of complying with government-ordered water restrictions.

The protection applies specifically when the homeowner is following a water restriction order from a municipality or water utility — in this case, Phoenix Water Services' Stage 2 Drought Response. The statute does not excuse failure to maintain landscaping under normal conditions; it only applies during periods of active restrictions. HOAs may still require removal of dead vegetation that creates a fire hazard, but they cannot impose fines for brown turf that results from following the two-day watering schedule.

If your HOA contacts you about lawn appearance during Stage 2, respond in writing. Below is a template you can adapt:

"This letter is to notify [HOA Name] that any brown or dormant turf at [your address] is a direct result of my compliance with Phoenix Water Services' Stage 2 Drought Response restrictions, currently in effect citywide. Under Arizona Revised Statutes § 33-1817, homeowners associations are prohibited from imposing fines or penalties for landscaping that does not meet community standards when the condition results from compliance with a government-issued water restriction order. I am watering on my assigned schedule as required by Phoenix Water Services. Please direct any further inquiries to Phoenix Water Services at 602-262-6251 or phoenix.gov/water."

Keep a copy of your water utility bill showing usage consistent with the two-day schedule, as it documents compliance if the HOA pursues the matter further.

Keeping your lawn alive on restricted water

Bermudagrass — the most common turf in Phoenix residential yards — is naturally suited to the two-day restriction schedule if you water deeply rather than briefly. On each allowed watering day, run irrigation long enough to wet the soil profile to 6–8 inches, then let the lawn dry fully before the next session. Shallow, frequent watering trains roots upward and increases heat stress vulnerability; under Stage 2, shallow watering on two days per week will not sustain turf. During summer months when soil temperatures exceed 85°F, Bermuda can tolerate brief dormancy — it will go straw-colored but recover when restrictions ease. Mow no shorter than 1.5 inches to shade roots and reduce moisture loss from the soil surface.

The more strategic move under Stage 2 is xeriscape conversion. Phoenix Water Services' Xeriscape Rebate Program currently pays $2 per square foot of turf replaced with desert-adapted landscaping — decomposed granite, native shrubs like brittlebush and desert marigold, or low-water ornamentals like red yucca and agave. A 500-square-foot lawn section converts to a $1,000 rebate. Cool-season overseed with perennial ryegrass is explicitly prohibited under current Stage 2 rules, which removes the traditional October practice of keeping lawns green through winter. This prohibition, combined with the rebate offer, makes the 2025–2026 restriction period a practical window to eliminate high-water turf entirely.

Phoenix water restriction FAQ

What are my exact assigned watering days under Stage 2 in Phoenix?

Your assigned watering days depend on your street address number and utility account zone — Phoenix Water Services does not use a single citywide odd/even calendar. Log into your account at phoenix.gov/water or call 602-262-6251 with your account number to get your specific two-day assignment. Do not guess based on neighbors; zone lines are irregular and two houses on the same block can have different assigned days.

When can I actually run my sprinklers on allowed days?

On your two assigned watering days, you may irrigate before 10:00 a.m. or after 6:00 p.m. The mid-day window from 10 a.m. to 6 p.m. is blacked out under Stage 2 rules. Running sprinklers at 11 a.m. on an assigned day is still a violation. Most Phoenix homeowners program controllers to run before sunrise to take advantage of cooler temperatures, lower evaporation rates, and no wind — early morning is the most efficient window even outside of restrictions.

Is the Phoenix $2/sq ft xeriscape rebate still available right now?

Yes. Phoenix Water Services' Xeriscape Rebate Program is currently offering $2 per square foot of qualifying turf removed and replaced with desert-adapted landscaping. You must apply before starting the conversion, have a pre-inspection, complete the work, and pass a post-inspection. There is a minimum project size and a per-account cap — contact Phoenix Water Services at 602-262-6251 or visit phoenix.gov/water for current cap amounts, as funding availability changes with budget cycles.

Can I wash my car at home during Stage 2?

Yes, but only with a hand-held hose that has a self-closing nozzle. Letting a hose run freely while washing — even briefly to rinse — is prohibited under Stage 2. Bucket washing is permitted without restriction. Commercial car washes operating with certified water-recycling systems are allowed to remain open; those without recirculating equipment face operational restrictions under the Stage 2 rules.

Does Phoenix Water Services actually monitor smart meters for violations?

Yes. Phoenix has deployed an Advanced Metering Infrastructure (AMI) network across the service area. These meters transmit hourly usage data, which Phoenix Water Services can analyze to flag accounts with water flow during prohibited mid-day hours or usage on non-assigned days. A data flag triggers a field inspection before a violation notice is issued — you will not receive a fine solely from meter data without a confirming site visit. If you receive a notice you believe is incorrect, file a written appeal within 15 days of the notice date.

My HOA is threatening to fine me for a brown lawn — what do I do?

Arizona Revised Statutes § 33-1817 prohibits your HOA from fining you for brown or dormant turf caused by compliance with Phoenix Water Services' Stage 2 Drought Response order. Respond in writing immediately, citing ARS § 33-1817 and documenting that your watering is within the Stage 2 schedule. Include a copy of your water bill as supporting evidence. HOAs that proceed with fines after receiving written notice citing § 33-1817 are exposed to legal challenge.

When will Stage 2 restrictions end?

Phoenix Water Services has tied the Stage 2 exit conditions to two measurable thresholds: SRP combined reservoir storage must exceed 60%, and Lake Mead must rise above the federal Tier 2 Shortage level. Both conditions must be met simultaneously for the city to step back to Stage 1. Given that SRP storage is at 52% and the October 2025–April 2026 rainfall season produced only 2.1 inches against a 6.4-inch normal, neither threshold is likely to be met before the 2026–2027 wet season at the earliest. Check phoenix.gov/water for monthly storage updates.

Can I use reclaimed water on my landscape to avoid the two-day limit?

If your property has access to Phoenix's reclaimed water distribution system — available in some master-planned communities and along designated reuse corridors — reclaimed water use for irrigation is subject to separate guidelines and is not counted against your two-day potable water schedule. Phoenix operates over 200 miles of reclaimed water pipeline serving
