Water Budgets are based on the amount of water required to keep lawns green.
Landscape beds with trees and shrubs require approximately 30% less irrigation.
Note, however, in most cases established trees and shrubs need little or no
supplemental water during the dry season.
-
Your Water Budget is based on yearly weather averages and does not factor in
rainfall. To switch your system off when it rains, contact an irrigation
contractor to install a Rain Sensor. Some water utilities provide rebates for
Rain Sensors. To see if you qualify, go to: savingwater.org.
