How water gets to your faucet
The Las Vegas Valley water system consists of a complex network of pipes, pumps, and reservoirs that work in harmony to connect more than 400,000 homes and businesses in our community.
Water pipelines, which can be larger than 8 feet or smaller than an inch in diameter, form the backbone of water distribution around the Las Vegas Valley, carrying water to buildings, fire hydrants, and other water use points.
Strategically situated throughout the valley are:
- 82 reservoir basins and tanks that collectively hold nearly a billion gallons of water.
- 55 pumping stations with the capacity to move more than 1 million gallons of water per minute.
- Nearly 7,000 miles of water transmission and distribution pipelines.
- 76 production wells and 26 recharge wells capable of producing more than 200 million gallons of water per day.
The Las Vegas Valley Water District manages this complex water distribution system to deliver water to more than 1.7 million people in Las Vegas and surrounding areas.
Investing in one of the nation's most reliable water systems
For more than a half century, the Water District and its customers have been investing in one of the nation's most reliable water delivery systems.
That investment has paid off. Instances of water main breaks in Southern Nevada are below the national average and our water system has an efficiency rating that is considered world-class.
Ensuring that our water delivery network remains among the nation’s most reliable requires proactive maintenance.
The Water District will invest more than $600 million to maintain, upgrade and expand the community’s drinking water system, including:
- $200 million to replace and repair aging water pipelines
- $142 million in several maintenance, repair and replacement projects
- $125 million in new reservoirs, pipelines and pumping facilities
- $100 million for backflow prevention to ensure water quality
- $15 million to maintain and replace groundwater wells and pumps
Two-thirds of capital projects scheduled focus on repairing and replacing aging water system components. The balance is split between water quality protection and new water facilities.
The Las Vegas Valley water system is among the most reliable systems in the nation with instances of water main breaks 8 times below the national average.
Construction costs for the community's water system account for more than half of the Water District's annual expenses; staffing costs account for less than one third of the not-for-profit agency's budget.
This investment in the water distribution system will keep costs down and save our community many millions of dollars, as proactively taking action is cheaper and less disruptive to residents than fixing water system failures.
Storing and pumping water around the valley
After water from Lake Mead (the source of most of Southern Nevada's drinking water) has been treated, it's pumped uphill to reservoirs throughout the valley. These reservoirs store the water until it's needed.
High-power pumps at pumping stations force water from the reservoirs to transmission pipelines, usually at night when the cost of power is less.
Major transmission mains move water from treatment plants and reservoirs, and, finally, gravity delivers water through distribution pipelines to your home or business.
Groundwater wells support peak demand
Wells are used to tap into our groundwater supply, mainly during summer periods of peak usage. They also are available for emergencies.
During some winters, treated Colorado River water is injected into the local aquifer, where it is stored for Southern Nevada's future use. This artificial recharge gives nature a helping hand in maintaining our groundwater supply.
Wells can pump anywhere between 400 and 4,000 gallons of water per minute. Combined, our 66 operational production wells can produce approximately 170 million gallons of water per day.
