About half the water used in a year is outdoors.

Reducing outdoor water use is the biggest way to save, has the largest impact on your water bill and it’s easy to do. You don’t even have to give up your green lawn! There are efficient and effective 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 you can water once or twice a month.
