Wait, don't irrigate!

Water is a limited resource in our dry climate, and using water wisely not only saves you money, but it's the right thing to do. Remember to adjust your automatic sprinklers monthly based on weather conditions.

Denver Water is enforcing its annual water rules, which run May 1 to Oct. 1.

  • Water during cooler times of the day – lawn watering is NOT allowed between 10 a.m. and 6 p.m.
  • Water no more than three days per week.
  • Do not allow water to pool in gutters, streets and alleys.
  • Do not waste water by letting it spray on concrete or asphalt.
  • Repair leaking sprinkler systems within 10 days.
  • Do not irrigate while it is raining or during high winds.
  • Use a hose nozzle with a shut-off valve when washing your car.

  • Penalties

    These rules are mandatory. Penalties are:

    • 1st violation — warning.
    • 2nd violation — $50 fine. 
    • 3rd violation — $100 fine.
    • Continued violations can result in suspension of service.
  • Watering times

    Use this chart as a starting point to determine the number of minutes to water each zone on the days you water. These times are averages. Adjust your watering minutes based on rainfall, type of grass or plants, sunny or shady locations and other characteristics.

    Watering two days a week should be sufficient during most of the summer. If needed, water a third day during extreme heat or dry periods. Water trees and shrubs as needed, but not between 10 a.m. and 6 p.m. Shrubs and perennials need half as much water as lawns.

    There are no assigned watering days, but never water a zone more than three days a week.

    Read more information and tips for watering your lawn. Keep track of your water use (past and present) and customize a water budget or irrigation schedule for your landscape needs.

  • Rules for watering new plant material

    Denver Water customers with new plants, including seed, sod, annuals, shrubs or trees, may water as necessary for up to 21 days. After 21 days, routine watering is limited to no more than three days per week and not between 10 a.m. and 6 p.m.

    To submit your request for a 21-day watering exemption, call 303-893-2444 or email customercare@denverwater.org.
