Water Efficient Irrigation

Water is the most important resource to sustain life and as the Earth’s population grows, the need for water grows. Water is being used and wasted faster than it can be replenished.

Irrigation Efficiency

Lawn irrigation can be 40-60% of your water bill
Watering less than two times a week is usually sufficient
Brown grass does not mean dead grass
Frequent watering promotes shallow roots instead of deep long lasting roots

For more information on how much you should water your lawn based on the weather visit: watermyyard.org

Landscape

Plant native and drought resistant plants that require less watering
Taller grass holds water more efficiently, don’t cut more than one third of the grasses length at one time
Buy or make a rain bucket to water your plants

Cycle and Soak Method

How Much Water Does your Irrigation System Use?

Try these calculations for your yard!

Print out this Water Usage Chart or use the calculations below.

First, Determine what kind of sprinkler head yo have:

Spray Head – Up to 3 gallons per minute (per head)
Rotor Head – Up to 9 gallons per minute (per head)

Then, Plug in the numbers below:

# of sprinkler heads ______ x # of gallons per minute (see above) ______x # of minutes scheduled per use ____ = # of gallons emitted per use

Do you have drip irrigation? it uses up to 1.5 gallons per minute in each 10×10 area. Plug in the numbers below if you have drip irrigation:

# of sq. ft. of irrigated lawn____ = # of gallons emitted per use x # of minutes scheduled per use ____ = # of gallons emitted per use.

Any variance above your normal household consumption could indicate any of the following:

Incorrect irrigation timer settings
A power surge could reset a timer to factory defaults, causing it to run more frequently than expected.
Check weekly and daily timers
Check for multiple timer programs (A, B, and C)
Broken or damaged sprinkler heads
Leaky or running toilet. (Public works has free tablets to help you check for toilet leaks)
