Control Your Controller

Good programming of your irrigation controller is critical to saving water. We can show you how in a few easy steps.

Setting your controller is as easy as 1-2-3

You only need to tell your controller three things to set it correctly.

  1. What time you want it to start.
  2. What day you want it to turn on.
  3. How long you want it to run each zone (station).

Don’t forget to make sure the date and time is set correctly on your controller and comply with your city’s watering rules!

Remember to turn off your controller in the winter!

Rule of Thumb

Use our recommended guidelines, then let your plants guide your final decision and remember there may be lots of reasons your plants don’t look as good as you want. Water is only one piece of the picture.

Landscape Watering

When to Water

  • Watering with a handheld hose is always allowed any time, any day.
  • Year round rules allow watering with a sprinkler any day without runoff before 11 a.m. and after 7 p.m.
  •  To be sure you are always in compliance, set your irrigation system to Stage 1 or Stage 2 rules, so if things change while you’re away – you’re good to go!
  • During Stage 1, you can water with a sprinkler one day a week based on the last digit of your street address as shown in the left column of the table. Water before 11 a.m. and after 7 p.m.
  • During Stage 2, your day remains the same but you may only water from 7-11 a.m. and 7-11 p.m.
  • You are never allowed to have runoff onto streets, parking lots and sidewalks as a result of irrigation.
  • For additional drought rules, go to saws.org/WhenToWater.
