The Southern Nevada Water Authority (SNWA) has selected Stantec, a global sustainable design and engineering company, to help deliver its $125 million Stage II Reliability Upgrades Project to support long-term sustainable and resilient water for the Las Vegas Valley.
“We’re incredibly excited to support SNWA on this critical water reliability project,” said Margaret Regan, Stantec project manager, based in Las Vegas. “Drought impacts have only increased the need for a reliable and sustainable water source. We look forward to helping the Las Vegas Valley have a safe and sustainable water delivery system for decades to come.”
The water supply of many major urban areas in the United States is at risk due to aging infrastructure, water scarcity, a lack of resiliency to extreme weather events, and insufficient system capacity. In August of 2021, federal officials issued Lake Mead’s first-ever water shortage declaration. Two decades of drought have significantly reduced Lake Mead’s water level, increasing the need to build systems that support sustainable, resilient, and redundant water distribution and meet the Las Vegas region’s current and future needs.
Project at a Glance
The Hacienda Pumping Station is one of the Valley’s water supply conduits, meeting about 35 percent of the area’s water demand, equivalent to 180 million gallons per day (MGD). In service since 1980, the pumping station requires system upgrades and replacements to protect against aging, provide reliability, and prevent water loss.
Stantec’s role on the Stage II Reliability Upgrades Project will include the design of the new Flamingo Pumping Station and the design of approximately two miles of interconnecting pipeline from the station to the Pittman Lateral, which conveys water to the central Las Vegas Valley.
Delivering the new 90 MGD Flamingo Pumping Station will serve two primary functions: to provide backup to the existing Hacienda Pumping Station (which has served the area for decades) in the event it is out of service and to supplement the capacity of Hacienda during periods of very high demand. Future projects will include rehabilitating portions of the Pittman Lateral and localized improvements to enhance the water system’s reliability along this central corridor.
The project is part of SNWA’s Major Construction and Capital Plan (MCCP) to help identify and deliver additional water resources, major system repairs and replacements, and water quality enhancements across the Las Vegas Valley. The 2020 MCCP includes 22 projects totaling an estimated $3.17 billion.
Stantec’s preliminary design for the Stage II Reliability Upgrades Project is expected to be complete in February of 2022.
