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.
In 2021, Thornton City Council adopted permanent Water Use Rules into City Code. The following turf/lawn irrigation rules will be enforced April 1 – October 31 (watering vegetable gardens and plant materials are not included):

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.
