With winter about to wrap Southern Nevada in its chilly grip, it’s time to save water by changing your watering clock to follow the community’s mandatory winter watering restrictions.
From Nov. 1 through Feb. 28, sprinkler irrigation is limited to one assigned day per week; sprinkler watering is always prohibited on Sunday. Find your assigned watering day at snwa.com.

If you have water-efficient plants and trees in your landscape—which need much less water than grass to thrive in even the coldest months of the year—you can save even more water by running your drip system once every seven to 14 days for 30 to 90 minutes. When in doubt, remember this simple five-word rule of thumb: Drip It, Don’t Drown It!
To extend your water savings and manage your monthly bill this season, follow these handy tips:
- Set your spray irrigation for grass to water during the mid-morning hours to avoid freezing and prevent ice from forming on lawns and sidewalks.
- Water grass only on your one assigned watering day.
- Change the time on your irrigation clock to coincide with the end of Daylight-Saving Time on Sunday, Nov. 2.
- Follow the seasonal watering restrictions year-round. The average customer can save up to $300 annually on their water bills.

Reducing the amount of water used on landscapes is critical because most of Southern Nevada’s water is consumed outdoors, and once it’s used, it’s gone for good. In contrast, the water we use indoors for bathing, washing dishes and clothes, and cooking is captured, highly treated, and returned to Lake Mead, where it can be reused. This cycle helps extend our community’s water supply. That’s why when it comes to outdoor water use, every drop truly counts.
