Assigned watering days are mandatory for all customers.

Running your landscape irrigation system outside your assigned days is water waste and may result in a water-waste fine.

Report water waste

Conservation and water efficiency are critical to meeting Las Vegas’ current and future water needs. Report water waste when you see it by filling out a water waste report form.

Winter watering restrictions are in effect.

Additional watering restrictions

In addition to watering on your assigned days, keep the following in mind when setting a schedule on your irrigation clock:

  • Sprinkler watering on Sundays is prohibited.
  • Watering restrictions also apply to drip irrigation. Drip irrigation systems deliver water more slowly and efficiently, and they should run longer but less frequently than sprinkler systems. The length of each watering should be determined by the emitter flow rate, soil type and weather conditions. See our drip watering tips for details.
  • For lawns watered by sprinklers, water no more than 12 minutes total. On your assigned watering days, water in three 4-minute cycles, with about an hour between each cycle if using pop-up sprinklers. Water for about 12 minutes each watering cycle if using rotating sprinkler heads. See our sprinkler tips for details.
  • Watering with a handheld hose and supervised testing of your irrigation system are allowed any time.
  • Watering new or reseeded landscapes daily for up to 14 days is allowed once per calendar year. Call 702-822-8571 before the planting takes place so we can make note of this on your water account. See more water waste exemptions.

Winter watering restrictions

Mandatory watering restrictions limit landscape irrigation to one assigned day per week from Nov. 1 through Feb. 29. Sprinkler watering on Sundays is prohibited.

Watering on a day other than your assigned watering day is considered water waste and may result in a fee.

Winter watering tips

  • Aerate your lawn. Aeration pulls tiny plugs from the soil, allowing water to be better absorbed.
  • Bermuda grass goes dormant in the winter so it doesn't need much water. Irrigate Bermuda grass just once per month November through March.
  • Avoid afternoon winds and reduce the risk of icing by watering in the midmorning.
  • Add a protective mulch on the soil around your plants to trap moisture.
  • Drip irrigation may occur any day of the week, but must not exceed one day in winter.

Standard time change

Don't forget to set your irrigation clock back an hour when standard time begins on the first Sunday in November at 2 a.m. This also is a great time to check your clock's batteries.
