Restricting outdoor water use

Nearly all the water we use indoors in Southern Nevada is recycled. However, water used outside evaporates and cannot be recycled. Water used outside is sometimes referred to as "consumptive use," because it is "consumed" rather than recycled.

Approximately 60 percent of Southern Nevada's water is used outdoors. This means it doesn't earn return-flow credits and is counted against our Colorado River water allowance. For this reason, our conservation rebates and programs focus on reducing water use outdoors.

Seasonal watering restrictions

Assigned watering groups are mandatory for all municipal water customers. Running your sprinkler irrigation system outside your assigned days is water waste and may result in a water-waste fee or citation. Find your watering group on our website or check your monthly water bill for your assigned group. Sprinkler watering on Sunday is prohibited.

From May 1 through Aug. 31, watering restrictions prohibit landscape irrigation between the hours of 11 a.m. and 7 p.m. Sprinkler watering on Sunday is prohibited.

Mandatory watering restrictions limit landscape irrigation to three assigned days per week from Sept. 1 through Oct. 31.

Mandatory watering restrictions limit landscape irrigation to one assigned day per week from Nov. 1 through Feb. 28.

Mandatory watering restrictions limit landscape irrigation to three assigned days per week from March 1 through April 30.

Preparing for the future

Hey Las Vegas — There are better ways to prepare for the future. We're in a drought, so using less means more. Change your watering clock to three days a week to save water.

Day of rest

Nothing beats a lazy Sunday afternoon and even your sprinklers want in on that action! No sprinkler watering on Sundays.

Vehicle and surface washing

Water restrictions limit the washing of vehicles and prohibit or restrict surface building and equipment washing.

Vehicle washing

Personal vehicles may be washed at residential properties once a week per vehicle and requires a positive shut-off nozzle on the garden hose. There is no limitation on how often you can wash your vehicle if the guidelines for commercial vehicles are followed or a high-pressure, low-volume sprayer is used.

Commercial vehicle washing is prohibited except where water is captured to a sanitary sewer through approved methods or where a high-pressure, low-volume sprayer using less than 10 gallons per vehicle is used.

Mobile car washing is allowed if the company uses a high-pressure, low-volume sprayer and less than 10 gallons of water per vehicle. We also recommend you use a Water Smart Car Wash.

Surface, building, and equipment washing

The washing of surfaces, buildings and equipment is prohibited unless water is discharged to a sanitary sewer through approved methods or contained on site. This includes surface washing by restaurants and fast food chains.

Fountains and water features

All fountains and water features using water provided by an SNWA member agency are subject to the water restrictions below. This includes the use of water that has been recycled or reprocessed by the customer.

Single-family residences can have fountains and water features with a surface area of less than 25 square feet.

Fountains and water features are prohibited for commercial use, with the following exemptions:

  • Fountains and water features supplied by privately-owned water rights
  • Fountains or water features that are necessary and functional components serving other allowable uses (for example, storage ponds on a golf course or aeration devices)
  • Indoor water features or features with most the total water volume contained indoors or underground
  • Recreational water parks, both public and private
  • Fountains and water features at resorts as defined by the governing jurisdiction
  • Fountains or water features necessary to sustain aquatic animals, if such animals are of significant value and have been actively managed within the water feature prior to declaration of drought

Mist systems

Residential mist systems are allowed under water restrictions, but each jurisdiction has regulations limiting commercial use to certain months and times of day. Contact your local water provider for specific information.

Golf courses

Golf courses are subject to an annual water budget of 6.3 acre-feet of water per irrigated acre, with appropriate surcharges applied to any water used over the budgeted amounts. Surcharges are assessed on an annual basis and are in addition to the price paid for water. Courses that go over their water budget have significant financial penalties assessed to the excess water use.

Golf courses are water-budgeted based upon acre-feet of water (including potable, raw, reclaimed and recycled water) for each acre currently being irrigated. The irrigated acreage includes lakes and ponds existing within a golf course and lakes and ponds serving, in total or in part, as a golf course irrigation reservoir. Once measured, the irrigated acreage shall remain fixed, thus creating incentive for golf courses to convert unneeded turf to other styles of water-efficient landscaping. If a golf course expands its course by increasing the number of playing holes, a new irrigated acreage will be determined.

Homeowners associations

Most government jurisdictions in the Las Vegas Valley have laws that prevent a homeowners' association (HOA) from restricting the installation of a water-saving landscape. An HOA may require homeowners to submit landscape design plans for approval; however, the HOA cannot require a homeowner to install grass nor can it prohibit water-efficient landscapes. An HOA may restrict the use of some types of landscape materials, such as artificial turf. To avoid problems, review all appropriate HOA policies that may apply to your new landscaping project before proceeding.

Note: Restrictions may vary based on individual jurisdictions. Contact your local water provider for specific information.
