Beat the Peak

Watering of landscapes drives Goodyear’s use of water in the summer.  Usage spikes from an average of about 5.5 million gallons of water (December-February) each day to close to 11 million gallons of water a day (June-August) and as high as 13 million gallons a day on some days.  

The city must build its infrastructure to produce and deliver water every time someone turns on the faucet every day of the year.  So the highest days determine how much is built, and what the cost is for that system.

You can help cut that highest day usage! We now offer free water usage estimates so you can see if you are on track with your water use. 

Cut Your Peak: Give Your Irrigation a Vacation 


Goodyear needs your help to beat the peak. It’s easy—give your irrigation a vacation.

The water system’s daily usage is the combined (think stacked) usage of all customers.  So if customers that use high volumes of water on one day can split it between days we can cut the peak (the height of the stack) before plants will even notice.  

How could you do this?  Split your watering.  If you have some turf in the back yard, some more in the front, desert plants in back and a vegetable garden you can use a lot of water in one day if it all waters the same day.  But it does not need to.


Show me what to do:

1.  Water only container plantings, new seedlings, and vegetable/annual plantings every day. 
IF THE PLANTS ARE WATERED DEEPLY ENOUGH everything else will be fine being watered less often.


2.  Water plants according to their needs.  Watering too often kills.
See sample schedule for June before Monsoon below. 
June intervals before monsoon

Turf - Every 4 days
Desert -   Every 7 days
Vegetables -  Daily

See the Central Arizona watering guideline summary for intervals for other months.  


Now, instead of using 365 gallons on the Combined One Day Watering, the peak will be on 240 gallon days when desert, back turf and vegetable plantings are watered.  And the desert plants will thrive on the less frequent watering.


3.  Water deeply so you don’t need to water often. It is better for the plants. 
Rule of thumb for depth is long enough to reach:
8-12 inches deep for turf
2 feet for bushes
3 feet for trees 
How to measure depth to water (link to water use it wisely)


4.  Turn it off!
When it rains, go out and turn it off. It’s embarrassing and wasteful to run sprinklers or drip in the rain.  Better yet, go out when the clouds are certain to bring rain and turn it back on if they don’t.

Rainfall What to Do

0 - turn it back on after rain misses your yard
< ½ " - turn it on in two days
> ½ " - delay watering one full watering interval 
Or buy a rain sensor to do this work for you! They are cheap and keep you out of the rain.


5.  Take them off.
Native and desert-adapted plants don’t need supplemental watering once established.
Cap the lines to desert adapted trees after two summers or three years.  Their roots should be able to get water enough without special watering from natural rainfall and what drips to them from nearby plants.
Don’t water cactus and other succulents (water-holding) plants unless they look shrunken.  Root rot kills and over-watering causes it.
