ABOUT HALF OF ALL WATER USED IN A YEAR IS OUTDOORS.
Reducing outdoor water use is the easiest way to save and has the largest impact on lowering your water bill. You don’t even have to give up your green lawn! There are smart watering practices, low-water plants and grasses, hardscaping features, and other water-wise options that let you stay green while caring for the blue.

October-April: Winter Watering
During colder months, snow does a good job of keeping trees, shrubs, perennials, and lawns hydrated so you don’t have to. If it’s over 40 degrees and there’s no snow on the ground, you can water once or twice a month.
