Change Your Clocks, Check Your Sprinklers, and Replace Your Batteries!

It’s that time of the year again! As you ‘fall backward’ and set your clocks, jump into action and check your irrigation controllers! The change in season is a great reminder to check your batteries for your irrigation controllers.  The City of Corona Department of Water and Power also offers a rebate of $200 for a smart controller. These smart controllers will adjust automatically and water based on the weather here in Corona. Visit DWP’s website for more information.

check your sprinklersUsing Daylight Saving Time as a reminder to check your irrigation system for leaks and to reset your controller can save significant amounts of water. You will not only gain an hour of sleep, but you will also gain savings on your next water bill! Checking for leaks and reducing irrigation times for fall will reduce the possibility of over-watering and help keep you within your water budget.

When checking your irrigation system, follow these steps:

  • Replace the battery, if there is one, in the irrigation controller and adjust the settings for Daylight Saving Time.
  • Remember to check your controller after a power outage; a power outage will reset your irrigation timer to its default setting which can be upwards of 10 minutes per station every day.
  • Check the settings to determine the number of days and minutes the system is watering the lawn and gardens. Odd numbered addresses can water on Saturday, Monday, and Wednesday, and even-numbered addresses can water on Sunday, Tuesday, and Thursday.
  • Take advantage of the lower evaporation rates when temperatures are cooler by watering in the early morning or in the evening. Water only during the hours of 8 p.m. and 10 a.m. Watering during the cooler parts of the day can save 25 gallons each time you water.
  • Reduce the number of minutes on your irrigation controller stations. At this time of year, the weather will begin to cool, and there are less hours of sunlight. Your outdoor budget will go down, and so should the minutes on your irrigation controller.
  • Run the irrigation system to ensure that all the sprinkler heads are working properly and provide accurate coverage. Make sure the sprinkler heads are only watering your lawn and plants – not the house, sidewalk, driveway or street. Adjusting the sprinkler heads to deliver water where it is needed can save 12 to 15 gallons each watering cycle. If your sprinklers need an upgrade, the City of Corona Department of Water and Power offers 25 free sprinklers nozzles to all of our customers! Please visit for more information.
  • Look for continually damp spots in the yard or places where water pools, as these could be signs of a leak in the irrigation system.

If you think you have a leak, follow these simple steps to use your water meter to detect the leak.

  1. Make sure all running water/devices are shut off inside and outside of your home.
  2. Go to your water meter box and remove the lid. Please use caution as the lid may be heavy.
  3. Look at the flow indicator. If it is spinning, water is passing through your meter and you may have a leak.
  4. Repeat the test to be certain all water is off.
  5. If you suspect a leak, try to locate it and fix it immediately.11.1.14 Change Clocks and Check Sprinklers
