Las Vegas NV Water Restrictions 2026

Current water restrictions in Las Vegas, Nevada

Las Vegas is under a Year-Round Mandatory Seasonal Schedule, currently limiting outdoor landscape watering to 3 days per week through April 30 under the spring schedule enforced by the Las Vegas Valley Water District (LVVWD).

The LVVWD, in coordination with the Southern Nevada Water Authority (SNWA), administers these restrictions year-round under a tiered seasonal framework rather than as a drought emergency response. The rules are permanent policy, reflecting Southern Nevada's structural water scarcity tied to the Colorado River and Lake Mead's long-term decline. Nevada receives just 300,000 acre-feet annually from the Colorado River — the smallest allocation of any Lower Basin state.

The restrictions apply to all residential, commercial, and municipal landscape irrigation within the LVVWD service area, which covers Las Vegas, North Las Vegas, Henderson, Boulder City, and unincorporated Clark County communities. The trigger for seasonal changes is calendar-based, not drought-stage based: spring runs March 1–April 30, summer May 1–August 31, fall September 1–October 31, and winter November 1–February 28.

State-level context reinforces local rules — the SNWA operates under Nevada's mandatory year-round conservation framework, and Lake Mead's elevation has hovered near or below Tier 1 shortage thresholds (1,075 feet) since 2021, prompting federal shortage declarations that reduce Nevada's annual Colorado River draw.

Practically: a resident wanting to run sprinklers on a Wednesday morning in April can do so — provided Wednesday is one of their three assigned days, they start before 11:00 a.m. (during May–August the cutoff tightens further), and they never water on Sundays. A resident who misses their assigned days cannot make up that watering on a non-assigned day, even in summer heat.

Watering schedule and allowed days

Your assigned watering group (A through F) is based on your street address. Enter your address at the LVVWD's watering schedule lookup tool at lvvwd.com to find which days apply to your property. Group assignments spread irrigation demand across the week so the distribution system isn't overwhelmed on any single day.

Multi-family residential properties and commercial accounts follow the same group assignment framework but may have separate meters for common-area irrigation versus individual units. HOA-managed common areas must comply with the same group schedule as any residential parcel — there is no commercial exemption from day-of-week restrictions. Golf courses operating under SNWA-negotiated conservation agreements are subject to separate contract terms, not the standard A–F schedule.

When prioritizing your limited watering days, established trees should receive water first. Drought-stressed desert willow (Chilopsis linearis), velvet mesquite (Prosopis velutina), and blue palo verde (Parkinsonia florida) — all common in Las Vegas landscaping — can sustain permanent damage if missed during consecutive summer watering days. Deep, infrequent watering on assigned days benefits these species more than shallow daily misting.

What happens if you violate restrictions in Las Vegas?

LVVWD enforces the schedule through a combination of field conservation officers who patrol neighborhoods, smart meter data analysis that flags irrigation anomalies on non-assigned days, and a public reporting system. Residents can report violations by calling 702-870-4194 or through the LVVWD website. Officers respond to reports typically within one to three business days, and the meter data can confirm whether irrigation ran on a prohibited day without requiring a field witness.

If you receive a water-waste fee and believe it was issued in error — for instance, if a controller malfunctioned or a tenant acted without your knowledge — contact LVVWD directly at 702-870-4194 to request a review before the billing cycle closes. First-time fee disputes tied to documented equipment failure are generally reviewed on a case-by-case basis, though the outcome is at LVVWD's discretion.

Other outdoor water rules

Beyond lawn irrigation schedules, Las Vegas enforces several additional outdoor water rules that matter in the desert climate:

• Nonfunctional turf removal (effective January 1, 2027): Under Nevada Assembly Bill 356, decorative grass that people don't walk or play on — medians, building strips, commercial frontages — must be removed. Approximately 3,900 acres of nonfunctional turf across the Las Vegas Valley are affected. Installation of new nonfunctional turf is already prohibited.
• Pool filling and refilling: Pools may be filled any day, but topping off should be done on assigned watering days where feasible. Pool covers are strongly recommended — an uncovered pool in Las Vegas loses roughly 7–8 feet of water per year to evaporation.
• Car washing: Washing vehicles at home must use a hose with a self-closing nozzle. Commercial car washes that recycle water are permitted without restriction.
• Decorative fountains: Recirculating fountains are permitted. Fountains that drain or discharge water rather than recirculate are prohibited.
• Pressure washing: Permitted for structures and hardscape, but running water continuously onto pavement or into the street is prohibited as water waste.
• Irrigation runoff: Letting sprinklers run onto sidewalks, streets, or gutters is a violation regardless of which day it occurs.
• Construction water: Dust control and construction water use must comply with SNWA's commercial account requirements; potable water cannot be used for dust suppression where reclaimed or non-potable water is available.

Water source and infrastructure

Approximately 90% of Southern Nevada's water supply comes from the Colorado River, stored and delivered through Lake Mead on the Nevada-Arizona border. Lake Mead — the largest reservoir by volume in the United States when full — is fed by the Colorado River upstream and regulated by Hoover Dam. LVVWD draws water through two intake tunnels embedded in the lakebed: Intake No. 1 (active when the lake is above roughly 1,050 feet elevation) and Intake No. 3, a deep-water tunnel completed in 2015 that functions even if the lake drops to about 875 feet.

Raw Colorado River water is delivered to the Alfred Merritt Smith Water Treatment Facility near Boulder City — the primary treatment plant for Southern Nevada — where it is filtered and treated before distribution. A second facility, the River Mountains Water Treatment Facility, provides additional capacity. Combined, these plants can treat over 600 million gallons per day.

The remaining roughly 10% of supply comes from Las Vegas Valley groundwater, drawn from the regional alluvial aquifer system beneath the valley floor. LVVWD manages groundwater extraction carefully because historic over-pumping caused significant land subsidence in parts of the valley during the mid-20th century.

One unique aspect of Las Vegas's water accounting: Nevada is credited for nearly all indoor water that is treated and returned to Lake Mead via the Clark County Water Reclamation District's return-flow credits system. This means outdoor water — which is consumed by evaporation and plant uptake and never returned — is functionally far more expensive from a water-budget standpoint than indoor use. It is the primary reason the turf removal law targets decorative outdoor irrigation so aggressively.

Since 2002, per-capita water use in the Las Vegas Valley has dropped 48% even as the population grew by approximately 750,000 residents — a result of mandatory conservation, rebate programs, and the turf removal initiative.

Brown lawn protections in Nevada

Nevada Revised Statutes § 116.31075 prohibits HOAs from fining homeowners for reducing or eliminating landscaping irrigation during a declared water shortage or when complying with mandatory watering restrictions issued by a water authority. If your lawn goes dormant or turns brown because you are following LVVWD's mandatory seasonal schedule, your HOA cannot penalize you for the resulting appearance.

The statute also prohibits HOAs from requiring a type or quantity of landscaping that would be inconsistent with the water restrictions in effect. This means an HOA cannot demand you maintain lush green turf if doing so would require watering on non-assigned days or violating the mandatory schedule. HOAs may still require that dead plant material be removed and that properties not become unsightly beyond water-related dormancy.

If your HOA sends you a violation notice related to lawn browning during mandatory LVVWD restrictions, use a written response referencing the statute and your compliance with the current watering schedule. Here is a template:

"Dear [HOA Board/Management Company]: I am writing in response to the violation notice dated [date] regarding the appearance of my lawn at [address]. I am currently in full compliance with the mandatory watering schedule issued by the Las Vegas Valley Water District (LVVWD) under its Year-Round Mandatory Seasonal Schedule. Under Nevada Revised Statutes § 116.31075, homeowners associations are prohibited from imposing fines or penalties for landscape conditions that result from compliance with mandatory water restrictions. I respectfully request that this violation notice be rescinded. Please contact me if you require documentation of my assigned watering group or the current LVVWD schedule."

Lawn care during restrictions

Las Vegas's Mojave Desert climate — with summer highs regularly above 110°F, annual rainfall under 5 inches, and intense solar radiation — means most traditional turfgrass struggles without significant irrigation. The grasses that can realistically survive here under current restrictions are limited:

For Bermudagrass — by far the most common lawn in Las Vegas — the 3-day spring schedule is generally sufficient if each watering session runs long enough to wet the soil 6–8 inches deep. Shallow, frequent watering encourages shallow roots that collapse under summer heat. During the summer 6-day schedule, cycle your irrigation controllers to water at night or early morning before the 11:00 a.m. cutoff to minimize evaporation loss, which can exceed 30% for midday sprinkler use in July. Mow Bermuda at 1.5–2 inches in summer; scalping it stresses the plant and increases water demand.

Many Las Vegas homeowners are converting traditional turf areas to xeriscape using desert-adapted plants: creosote bush, autumn sage, desert marigold, and decomposed granite mulch. The SNWA's Water Smart Landscapes rebate pays up to $3 per square foot (capped at $1,500 for residential accounts) for removing existing grass and replacing it with approved low-water-use plants or non-organic groundcover. Given the approaching 2027 nonfunctional turf ban, converting decorative strips now avoids a mandatory future removal cost and generates immediate rebate income.

Common questions about Las Vegas water restrictions

What days can I water my lawn in Las Vegas right now?

Your specific allowed days depend on your assigned watering group (A through F), determined by your street address. During the current spring schedule (through April 30), each group is assigned 3 days per week — never including Sunday. Enter your address in the schedule lookup tool at lvvwd.com/conservation/mandatory-watering-schedule/ to find your exact days. When the schedule shifts to summer on May 1, your group will expand to 6 permitted days per week, but the 11:00 a.m.–7:00 p.m. watering blackout also takes effect.

Can I water on Sundays in Las Vegas?

No. Sunday watering is prohibited year-round for all watering groups under the LVVWD mandatory schedule, with no exceptions. This applies to sprinkler systems, hose-end sprinklers, and oscillating sprinklers. Drip irrigation and hand watering with a shut-off nozzle are exempt from the day restriction and may be used on Sundays.

What is the nonfunctional turf ban and does it affect my yard?

Nevada Assembly Bill 356 prohibits the use of nonfunctional turf — decorative grass that is not regularly used for recreation or play — in the Las Vegas Valley starting January 1, 2027. This primarily targets grass in road medians, commercial building frontages, parking lot borders, and HOA common areas. A backyard lawn where children or pets play is generally considered functional and is not targeted. However, a grass strip between the sidewalk and curb that no one uses would likely qualify as nonfunctional. The SNWA provides a detailed definition and property-type guidance at snwa.com.

Does LVVWD use smart meters to catch watering violations?

Yes. LVVWD's advanced metering infrastructure (AMI) transmits hourly water use data, allowing conservation staff to identify when irrigation runs on non-assigned days or during the prohibited midday window without requiring a field officer to be present. If your controller malfunctions at 2:00 p.m. on a prohibited day, the meter will record it. This data can be used to issue a water-waste fee even without a neighbor complaint or in-person observation.

What rebates does LVVWD or SNWA offer for removing grass?

The SNWA's Water Smart Landscapes rebate program pays up to $3 per square foot of removed grass, with a residential cap of $1,500 per application cycle. The removed turf must be replaced with approved desert-adapted plants, mulch, or permeable hardscape — not artificial turf (which SNWA no longer rebates). Apply through the SNWA portal before removal begins; retroactive applications are not accepted. Additional rebates are available for water-efficient irrigation controllers and pool covers through LVVWD's conservation programs at lvvwd.com.

Can I fill or top off my swimming pool during restrictions?

Pool filling is not subject to the day-of-week restrictions that apply to landscape irrigation. You may fill or top off a pool on any day. However, LVVWD strongly recommends using a pool cover to reduce evaporation — Las Vegas pools can lose 7–8 feet of water annually to evaporation without a cover, which is a substantial volume given the city's desert climate and high summer temperatures.

My sprinkler head broke and flooded the sidewalk — will I get a fine?

Irrigation runoff onto sidewalks, streets, or gutters is a water-waste violation regardless of whether the runoff occurred on your assigned day. A broken sprinkler head that floods a sidewalk is citable. Repair broken heads promptly; LVVWD conservation officers respond to runoff complaints quickly, and smart meter spikes from a broken head can also trigger a review. If a malfunction caused a violation before you could act, contact LVVWD at 702-870-4194 to explain the circumstances before a fee posts to your account.

Does Las Vegas's mandatory schedule apply to commercial properties?

Yes. Commercial properties within the LVVWD service area are assigned to a watering group and must follow the same seasonal schedule as residential customers. Large commercial and institutional accounts — including hotels, casinos, and master-planned communities — may have individually negotiated conservation agreements with the SNWA that specify alternative targets, but those agreements do not exempt them from day-of-week restrictions. Golf courses operating on recycled water from the Clark County Water Reclamation District are subject to separate SNWA contract terms.

What time can I water in Las Vegas?

Watering is allowed May-Aug: no watering 11am-7pm. No Sundays ever.. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in Las Vegas?

First offense: Water-waste fee on bill. Repeat violations: Citations and escalating fees. Contact Las Vegas Valley Water District (LVVWD) for the full enforcement schedule.
