Currently, 40 percent of the Las Vegas Valley gets its water through the South Valley Lateral (SVL) transmission system. While the rest of Southern Nevada’s water transmission laterals have redundant facilities to ensure water delivery in the event of an emergency, the SVL is a single-feed system. In 2017, a leak in the pipeline required the Southern Nevada Water Authority (SNWA) to coordinate major repairs with the City of Henderson and Las Vegas Valley Water District to keep water flowing to customers. The SNWA is constructing the Horizon Lateral to work in tandem with the SVL to provide system redundancy and increase reliability to the south part of the valley. Doa Ross, SNWA Deputy General Manager of Engineering, and Adriana Ventimiglia, Senior Program Engineer, talk about the planning and construction of this massive infrastructure project and its impacts on the economy and jobs in Southern Nevada.
