Mandatory watering schedule
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.
Winter watering restrictions
Mandatory watering restrictions limit landscape irrigation to one assigned day per week from Nov. 1 through Feb. 28. 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.
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.
- Running your landscape irrigation system outside your assigned days is water waste and may result in a water waste fine.
- Watering with a handheld hose and supervised testing of your irrigation system are allowed any time.
- 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 new or re-seeded 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.
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.

How to set your irrigation clock
Most irrigation clocks have programs A, B and C to help ensure different areas of your landscape are getting the right amount of water. Using them correctly will save water and money. For detailed directions on how to set your irrigation clock, refer to the product manual on the manufacturer's web site.
💦 Program A: Sprinkler irrigation
Water your lawn 3 times a day, 4 minutes each watering for each assigned watering day, scheduling start times at least one hour apart.
💧 Programs B and C: High-water use and water-efficient plants on drip systems
The types of drip emitters you use, variety of plants in your landscape, and soil conditions all play a role in figuring out how much to water your landscape when it comes to drip irrigation. To ensure efficiency, group high-water use plants on one program and low-water use plants on another.
