Winter Watering Restrictions | Southern Nevada

Winter Watering Restrictions

The Southern Nevada Water Authority mandates watering restrictions during the winter months. If you do not comply with the watering restrictions, you could be assessed a water waste fee. LV Yard Doctor can set your irrigation system to the proper restrictions for you if you are unsure of how to set the scheduling on your irrigation controller. 

Winter Watering Months

Mandatory watering restrictions limit landscape irrigation to one assigned day per week from November 1st through February 29th. Watering restrictions also apply to drip irrigation.

Winter Watering Days

Find your watering group on the SNWA website or check your monthly water bill for your assigned group. 

SNWA Winter Watering Schedule

Daylight Saving Time Ends

When daylight saving time ends each year, do not forget to reset your irrigation clocks. Daylight-saving time ends the first Sunday in November at 2 a.m. 

Sprinkler watering tips

Use the cycle and soak sprinkler irrigation method, which allows the soil to absorb water slowly and reduced the risk of runoff. Set each sprinkler station to run: 

  • 3 times a day
  • 1 hour apart
  • 4 minutes each watering session

Do not water on windy or rainy days

Winds can send sprinkler water in unintended directions, saturating the surrounding sidewalk, rocks and other hardscaping more than the lawn. Watering during rainy periods can cause soil over-saturation and waste-full runoff. Shutting of the sprinklers on windy or rainy days can save as much as 500 gallons of water per day. 

To keep landscapes healthy, follow these tips: 

  • Aerate your lawn. Aeration pulls tiny plugs from the soil, allowing water to be better absorbed. 
  • Bermuda goes dormant in the winter so it doesn't need as much water. Irrigate Bermuda grass just one time per month from November through March. 
  • Avoid the risk of icing from watering during the afternoon and water in the midmorning. 
  • Adding a protective mulch on the soil around your plants will trap moisture so you do not have to water as much. 
  • If frost or freeze damages a plant, leave it alone until warmer weather arrives and new growth appears. Pruning or transplanting a damaged plant may hurt or even kill it. 
  • Turn on sprinklers for a minute after you mow and scan for broken or misaligned sprinkler heads and broken pipes. 

Drip watering Tips

During winter, SNWA recommends running your drip irrigation system in a single cycle of 30 to 90 minutes, one day a week. The length of watering should be determined by the emitter flow rate, soil type and weather conditions.
