Drought Restrictions and Water Conservation

Water restrictions have been adopted by
local city and county governments to help
curb water use.

As a community, we've been dealing with drought conditions for more than a decade. Together, residents and business owners have removed thousands of acres of turf, planted desert landscaping and curbed water waste.

The community is currently ahead of schedule to achieve its water conservation goal of 116 GPCD by 2035.

Drought restrictions were adopted in 2003 to help Southern Nevada conserve water. Conservation efforts in the Las Vegas Valley have helped reduce the community’s Colorado River consumption by 28 billion gallons between 2002 and 2017, even as the population increased by nearly 660,000 residents during that time.

In 2017, Southern Nevada used 127 gallons per capita per day, representing a 36 percent decline the community’s per capita water use since 2002. (Note: This number reflects water from all sources used by residents and businesses served by municipal water providers, as well as recovered indoor water treated and returned to the Colorado River system and water used by 40 million annual visitors. Because different water agencies' calculation methodologies vary, comparing cities' water efficiency through the use of this metric is not recommended.)
