  • Mandatory winter watering restrictions: During the winter, sprinkler irrigation is limited to one assigned day per week. Watering restrictions also apply to drip irrigation. Sunday is not an optional watering day.
  • Drip watering: Drip systems deliver water more slowly and efficiently than sprinklers, which means plants on drip irrigation should be watered less often than grass irrigated by sprinklers. We recommend watering one day a week in winter.
  • Sprinkler watering: Water your lawn a maximum of 12 minutes on your watering day. Water in three 4-minute cycles with each cycle spaced out an hour.
  • Change all your clocks when Daylight Saving Time ends: Don’t forget to change the time on your irrigation clock when daylight saving time ends on the first Sunday in November.
  • Midmorning watering: Water in the midmorning to avoid the afternoon winds that keep your sprinklers from hitting their grass target. You also will reduce the risk of icing that can occur if you water during early morning or evening.
  • Save water on rainy days: Turn your irrigation clock off on rainy days or let a smart irrigation clock do the work for you.

Winter Watering Schedule in Effect November 1 in Southern Nevada

It may not officially be winter yet, but as the calendar rolls over and cooler temperatures set in, it’s time to change our landscape watering clocks to follow the community’s mandatory winter watering schedule.

In effect from November 1 through February 28, the winter watering schedule limits sprinkler irrigation to one assigned day per week; sprinkler watering is prohibited on Sunday. Find your assigned watering day at snwa.com.

Saving water—and managing your monthly bill—is even easier during the winter when you run your drip irrigation system on a recommended schedule of once every seven to 14 days for 30 to 90 minutes. When it comes to drip irrigation, keep a simple five-word rule of thumb in mind: Drip It, Don’t Drown It!

Here are more tips to help keep your landscape vibrant this winter while helping the community save water:
• Set your spray irrigation for grass to water during the mid-morning hours to avoid freezing.
• 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 November 2.
• Following the seasonal watering restrictions year-round can help the average customer save up to $300 annually on their water bills.

The amount of water we apply to our landscapes is critically important because it is used once and cannot be reclaimed. Conversely, the water we use indoors for cooking, bathing, and cleaning is reclaimed, highly treated, and returned to Lake Mead for reuse.  This recycling process helps extend our community’s water supply, making every drop count–especially outdoors.
