Las Vegas, Nevada relies on a complex and resilient water infrastructure designed to reliably deliver drinking water in one of the driest regions of the United States. The backbone of the system begins at Lake Mead on the Colorado River, which supplies nearly 90% of the region’s municipal water — pulled through multiple intake stations and low lake-level pumps that ensure access even as water levels fluctuate due to drought. That water is treated at major facilities like the River Mountains Water Treatment Facility, which sends finished water into a vast network of more than 7,000 miles of pipelines, storage reservoirs, and hundreds of pumping stations that move water across the valley to homes and businesses. Local groundwater wells supplement supplies during peak demand and emergency needs, and treated Colorado River water is even artificially recharged into the aquifer to bolster long-term resources. The system is managed regionally by the Southern Nevada Water Authority alongside local utilities like the Las Vegas Valley Water District, and includes extensive storage, pumping, treatment, and distribution assets that balance reliability, conservation, and sustainability in a desert environment.
