OUTDOOR WATER USE - LAWN WATERING & OTHER USES

We have not provided a calculation for lawn watering due to the many variables for Boulder households (lawn and garden size, sprinkler system differences, landscaping variables, etc.). Outdoor watering is the largest area for water use and we highly recommend reading the conservation and lawn watering tips at www.bouldersaveswater.net.

OUTDOOR WATER USE - OTHER USES

Water is used outdoors to wash cars, fill pools, rinse outdoor furniture and clean equipment.

Estimate the average number of minutes water is used outdoors for purposes other than lawn watering each week. Note: Choose '0 Minutes' during winter months when you are not watering outdoors
