<< Prev     Utilities     Next >>
The Southern Nevada Water Authority (SNWA) is a cooperative agency formed in 1991 to address Southern Nevada’s unique water needs on a regional basis. SNWA officials are charged with managing the region’s water resources and providing for the present and future water needs of Las Vegas Valley residents and businesses.

Record-Breaking Results
The Water Smart Landscape Rebate Program has helped the community upgrade more than 160 million square feet of lawn to water-efficient landscaping, saving the community billions of gallons of water each year.

More than 14,000 coupons have been distributed to participants in the Pool Cover Instant Rebate Coupon Program, which has contributed a total of 480 million gallons of saved water.

The Irrigation Clock Rebate Program gave financial assistance for customers to upgrade their landscape irrigation controllers to water-efficient models, facilitating replacement of nearly 2,000 controllers and saving the community more than 150 million gallons of water.

Since 2001, businesses participating in the Water Efficient Technologies Program have saved more than 1.75 billion gallons of water, and between 2002 and 2012, Southern Nevada’s consumption of Colorado River water decreased by approximately 29 billion gallons despite the addition of 400,000 residents.

Press Release
Community-wide efforts to conserve water in Southern Nevada go hand-in-hand with helping you save money on your water bill. With that in mind, the Southern Nevada Water Authority (SNWA) offers several rebate programs along with seasonal watering restrictions that can help you join your new neighbors in safeguarding our community’s most precious natural resource, while earning a little green on the side.

Mandatory seasonal watering restrictions
Each residential and business address in the Las Vegas Valley is assigned to a seasonal watering group, which identifies the days in which you can irrigate your landscape. Sunday watering is prohibited year-round.

Seasonal restrictions limit weekly watering to:Spring:
  • Spring: Three assigned days from March 1 through April 30
  • Summer: Landscape irrigation is permitted Monday through Saturday from May 1 through Aug. 31; however, watering is prohibited between the hours of 11 a.m. and 7 p.m., when water is often lost to evaporation from the heat and high winds.
  • Fall: Three assigned days from Sept. 1 through Oct. 31
  • Winter: One assigned day from Nov. 1 through Feb. 28

Water Smart Landscapes Rebate Program

Since its launch in 2000, the SNWA’s highly popular Water Smart Landscapes rebate program (WSL) has helped the community save more than 118 billion gallons of water, while the amount of turf converted would cover 3,215 football fields. If you’re unfamiliar with WSL, here’s how it works: For each square foot of thirsty turf you convert to water-efficient, desert-adapted landscaping, the SNWA will rebate $2 up to the first 5,000 square feet, and $1 per square foot of grass removed beyond the first 5,000 square feet. To participate, complete an application at or call (702) 258-SAVE (7283). Sample landscape designs and a plant search tool are available on the website to help you design a landscape that fits your lifestyle.

Pool Cover Instant Rebate Coupon
If you are a pool owner, you can save as much as 9,500 gallons of water each year that otherwise would be lost to evaporation with a pool cover. As a bonus, pool covers also limit windblown debris, which can drive up the cost of pool maintenance, while helping to conserve energy. The SNWA pool cover program provides a discount coupon for up to $50 or 50 percent off the purchase price of a typical pool cover, whichever is less. The program also provides up to $200 or half off the purchase (whichever is less) of a permanent, mechanical pool cover. Residential customers of SNWA member agencies may redeem one pool cover coupon per property address every 36 months at a participating retailer. Visit for a list of retailers and to download a printable coupon.

Smart Irrigation Controller Rebate Coupon
Smart controllers are irrigation clocks that use sensors and weather information to manage how much water is applied to your landscape each day. The smart controllers adjust watering times or shut off sprinklers automatically in response to environmental changes, such as rain, high wind or low temperatures. On average, they can reduce outdoor water use by an average of 15 to 30 percent. The SNWA’s rebate program offers 50 percent off the purchase price or up to $200, whichever is less. You can download and print the coupon from, then take it to one of our participating retailers for an instant rebate; or, you can purchase one of the smart controllers on our qualifying products list at the retailer of your choice and receive your rebate by mail.

Water Smart Car Wash Coupons
Taking advantage of the SNWA’s Water Smart Car Wash coupon can not only help you clean a dirty car, but conserve water at the same time. The coupons are redeemable at dozens of Water Smart Car Washes that recycle the water they use. This results in greater water savings than washing your car at home. Home car washing can use two to three times more water than a Water Smart Car Wash, and much of that water flows into the street and can’t be recovered or reused. Water Smart Car Wash coupons are easily accessible at along with a full list of participating locations throughout the valley.

n order to address unprecedented drought conditions and provide long-term protection of Southern Nevada's primary water storage reservoir—Lake Mead— the Southern Nevada Water Authority (SNWA) Board of Directors approved the construction of a new drinking water intake in May 2005.

The intake is designed to maintain SNWA's ability to draw upon Colorado River water at lake elevations as low as 1,000 feet above sea level. This will ensure system capacity if lake levels fell low enough to put Intake No. 1 out of service. It also will protect municipal water customers from water quality issues associated with declining lake levels.

Construction on this third intake is scheduled for completion in 2015. Once completed, Intake No. 3 will connect with the existing Intake No. 2 to convey water to SNWA's water treatment facilities. From there, the water will be piped to households and businesses.

Begun in 2008, the construction of Intake No. 3 is an enormous project involving a tunnel boring machine chewing through solid rock underneath Lake Mead and an intake structure two and a half miles offshore. More than 1,000 concrete truck loads were transported to the intake site on 143 barge trips.

The Southern Nevada Water Authority (SNWA) has received the "15 Year Directors Award of Recognition" from the Partnership for Safe Water, a national volunteer initiative developed by the Environmental Protection Agency (EPA) and other water organizations representing water suppliers striving to provide their communities with drinking water quality that surpasses the required federal standards.

The SNWA was presented the award for successfully completing the Self-Assessment and Peer Review phase of the Partnership program, a phase which consists of identifying factors that limit treatment plant performance.

"We are honored to receive this award, which reflects the commitment of our organization to providing a safe, reliable water supply," said Dave Johnson, director of Water Quality and Treatment for the Southern Nevada Water Authority. "Maintaining water quality that surpasses state and federal health standards is critical to the SNWA's mission. Being considered among the highest-performing water treatment facilities in the country is a rewarding achievement, and it is a level of performance that we will continue to build upon as both conditions in Lake Mead and the regulatory environment change. This award would not be possible without the professionalism and dedication of our entire team."

The Partnership currently includes more than 220 water utilities, collectively serving more than 85 million people. This represents more than 60 percent of the U.S. population served by surface water supplies.

Each utility has committed to the enhancement of drinking water quality and operational excellence in water treatment. As members of the Partnership, utilities make a pledge to their communities to improve their treatment operations to reduce the risk of exposure to microbial contaminants, namely Cryptosporidium, a parasite that can cause illness. By making this commitment, the member utilities' treatment practices undergo a rigorous review developed by national experts, and includes a four-phased, self-assessment and peer-review process.
