Water Use in Las Vegas

How Much Water Does Las Vegas Use? Water Use Per Capita The average household in Southern Nevada uses about 222 gallons of water per day. This has recently dropped from using 314 gallons of water per day. The southern Nevada Water Authority hopes that by the year 2035, water use will have dropped down to 199 gallons per day for each household. The majority of Southern Nevada’s water goes to residential use, both indoor and outdoor. Because of this, restrictions have been placed on certain aspects of water use such as the amount of lawn a household can own. Aside from residential use, a large amount of water is still used in other areas of communities, such as golf courses. A golf course can use up to 6.3 acre-feet of water per acre of land without penalty. That’s over 2 million gallons of water for each acre per year
