Goals and Facts

Southern Nevada has dramatically reduced
its water use since 2002.

Progressive, Comprehensive Water Conservation

Since 1991, the Southern Nevada Water Authority (SNWA) has developed and implemented one of the most progressive and comprehensive water conservation programs in the nation.

In the mid-1990s, the SNWA established a goal of 25 percent conservation by 2010, roughly equivalent to reducing water use by about 280 gallons per capita per day. Southern Nevada made consistent progress toward its conservation goal throughout the 1990s. Beginning in 2000, however, levels of conservation began to decline.

This set the stage for development of the SNWA’s Drought Plan, which went into effect in 2003. Following the implementation of the Drought Plan in 2003, conservation and drought savings rebounded and, by 2004, had surpassed the original goal.

Concerned about continuing drought conditions, the SNWA Board of Directors set the bar even higher in 2005, asking the community to reduce its average water use by an additional 20 percent by 2035.

Record-Breaking Results

The following years witnessed extraordinary conservation achievements. Participation in the SNWA’s rebate programs has realized record-breaking results:

  • The Water Smart Landscape Rebate Program has helped the community to upgrade more than 172 million square feet of lawn to water-efficient landscaping, saving the community billions of gallons of water each year.
  • More than 33,000 coupons have been distributed to participants in the Pool Cover Instant Rebate Coupon Program, contributing to a total of 420 million gallons of water saved annually.
  • The Irrigation Clock Rebate Program, which provided financial assistance for customers to upgrade landscape irrigation controllers to models that can increase water efficiency, facilitated replacement of nearly 2,000 controllers for residential and commercial properties, saving the community more than 134 million gallons of water annually.
  • Since 2001, businesses participating in the Water Efficient Technologies Program have saved more than 1.25 billion gallons of water annually.
  • For the past six years, the community has lowered its total system GPCD (gallons per capita per day) demand from 248 in 2008 to 205 in 2014—well ahead of the projected GPCD expected in order to meet the 2035 goal of 199.
  • The net consumptive water use in 2014 was 118 GPCD. This includes all customer sectors but refers only to the portion of water that is consumptively used since direct and indirect reuse allows the water to be used more than once. Net GPCD is more representative of Southern Nevada's water footprint on the Colorado River.
  • The SNWA’s Water Smart Homes Program is among the most successful water efficiency home programs in the country. More than 10,000 homes have been built via this program, resulting in an estimated savings of about 900 million gallons per year compared with traditional residential developments.

Between 2002 and 2014, Southern Nevada’s consumption of Colorado River water decreased by approximately 32 billion gallons, despite the addition of 520,000 residents during that decade.

Conserving Water Indoors

Southern Nevadans also can realize benefits from reducing water use indoors.

Indoor conservation measures will not help extend the community's water supply or improve our resistance to drought because virtually all water used indoors is already captured, treated and added back to the water supply.

However, saving water inside your home can save money on your water and power bills.

Conservation and Development of Additional Water Resources Needed to Meet Projected Demands

Additional conservation will continue to be an important element in planning and balancing the various water supply and infrastructure needs in Southern Nevada, as identified in SNWA's Water Resource Plan. Continued conservation, coupled with the acquisition and development of additional water resources, will allow the SNWA to meet projected water demands through 2060.
