Southern Nevada Water Authority

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.

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.
