SNWA headquarters in Las Vegas.

The Southern Nevada Water Authority (SNWA) is a government agency that was founded in 1991 to manage Southern Nevada's water needs on a regional basis in Clark County.

SNWA provides wholesale water treatment and delivery for the greater Las Vegas Valley and is responsible for acquiring and managing long-term water resources for Southern Nevada. [1]

From its inception, the SNWA has worked to acquire additional water resources, manage existing and future water resources, construct and operate regional water facilities and promote water conservation.

The SNWA is governed by a seven-member board of directors, which comprises one elected official from each governing board of the SNWA's seven member agencies. While the Board of Directors sets policy direction for the SNWA, the Las Vegas Valley Water District is responsible for the day-to-day management of the organization through an agreement between the SNWA member agencies.

Water supply and distribution

Southern Nevada gets nearly 90 percent of its water from the Colorado River. The other 10 percent of the water comes from groundwater that is pumped out through existing wells within Clark County. [3] Perchlorates in ground water in Henderson and associated runoff into the Las Vegas Wash has been a concern since 1997. [4] [5]

Treatment facilities

These facilities first treat the water with ozone to kill any potentially harmful microscopic organisms. As the water leaves the water treatment facilities, chlorine is added to protect it on the way to customers' taps. Since 2000, SNWA has also added fluoride to the municipal water supply. [6]
