Your Irrigation System

How much water does your irrigation system use? Keep an eye on the watering schedule and check monthly for leaks.

Monthly Maintenance

Your in-ground irrigation system can account for 50 to 70 percent of your home water use.

Like your car, your irrigation system requires regular attention. Monthly monitoring can reduce your water usage and help you save money and avoid water waste citations. Proper scheduling can lower water use while maintaining a healthy garden.

Every month, use the two-minute test program to check for:

  • broken and clogged heads
  • misaligned heads
  • long run-times and extra programs
  • overspray onto sidewalks, streets and driveways (always illegal and can result in citations year round)

Don’t forget to turn off your irrigation system during rainy weather and the cold months.

Have an Older System?

If your system is 10 years or older, replace your irrigation components with modern, water-efficient components, such as:

  • pressure-regulated spray heads and rotors
  • stream rotators
  • a rain sensor with rain delay
  • a controller with a seasonal adjust feature

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.
