Summer Watering Restrictions

Summer Watering Restrictions

While irrigation is permitted any day of the
week from May 1 until Sept. 1, your
landscape probably needs less.

From May 1 until Sept. 1, watering restrictions allow watering any day of the week.

However, consider taking Sundays off! Landscapes can stay healthy and look great with much less water. Taking just one day off each week can reduce your water use by 10 to 15 percent.

Monitor your landscape closely during the hot summer days and adjust watering times or days as needed.

Time-of-Day Watering Restrictions

Watering restrictions prohibit sprinkler irrigation between the hours of 11 a.m. and 7 p.m. from May 1 until Sept. 1.

During the hottest hours of the day, water is often lost to evaporation from the heat and high winds. Watering during restricted hours is considered water waste and may result in a water waste fee or citation.

You may hand water your landscape at any time of day, but use a hose with a positive shut-off nozzle.

When to Water

Water your landscape early in the morning, before sunrise, to reduce evaporation caused by wind and heat.

Sprinkler Watering Tips

Use the cycle and soak sprinkler irrigation method, which allows the soil to absorb water slowly and reduces the risk of runoff. Water four days per week and increase the schedule only if your landscape needs more water.

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

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.

Problem Areas

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.

Drip Watering Tips

During summer, SNWA recommends running your drip irrigation system in a single cycle of 30 to 90 minutes, three 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.
