Mandatory watering schedule
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. While you may water any day of the week, watering may not exceed the maximum number of days per week allowed by the restrictions. Experts agree that running drip irrigation less frequently is much better for plants than daily watering.
- For lawns, use the cycle-and-soak method for sprinkler watering. 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.
- 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.
Sprinkler watering tips for all seasons
Use the cycle-and-soak method
The cycle-and-soak sprinkler irrigation method allows soil to absorb water slowly and reduces the risk of runoff. Here’s how it works:
- Water 3 times a day
- 1 hour apart
- 4 minutes for each watering
- Water before sunrise May through October
Drip irrigation is usually needed less frequently than sprinkler irrigation. See our drip watering tips for details.
Don't water on windy or rainy days
Winds can send sprinkler water in unintended directions, saturating the sidewalk more than the lawn. Watering during rainy periods can cause soil over-saturation and wasteful runoff. Shut off the sprinklers on windy or rainy days and save as much as 500 gallons of water a day.
What to do if you have brown spots
If you notice brown spots in your lawn, check your sprinklers to see if any of the heads are broken or twisted. Also, check to see that your sprinklers are popping up 4 inches above the grass. You may water by hand with a hose. To break down surface tension and allow for better water absorption, add a tablespoon of liquid soap to a gallon of water and drench the brown spots with the mixture.

Fall watering restrictions
Mandatory watering restrictions limit landscape irrigation to three assigned days per week from Sept. 1 through Oct. 31. Sprinkler watering on Sundays is prohibited.
Watering on days other than assigned watering days and watering during restricted hours are considered water waste and may result in a fine.
Fall drip irrigation
During fall, we recommend that you run your drip irrigation system in a single cycle of 30 to 90 minutes, two days a week. The length of each watering should be determined by the emitter flow rate, soil type and weather conditions. Experts agree that running drip irrigation less frequently is much better for plants than daily watering. See our drip watering tips for details.
Drip irrigation may occur any day of the week, but must not exceed three assigned days.
