Conserving Water Outdoors

More than 50 percent of water consumption happens outdoors, so it also provides the greatest potential to reduce consumption.

Tips for Outdoor Water Conservation:sprinkler

  • Make sure your irrigation system is functioning properly.
  • Get a FREE sprinkler inspection (also known as an irrigation audit) from the Center for ReSource Conservation, a non-profit  partner in Longmont’s efforts to conserve water.
  • Do not water lawn or gardens more than two days per week.
  • Do not water lawns or gardens between the hours of 10 am and 6 pm.
  • Adjust irrigation heads to avoid overspray onto the sidewalks and streets.
  • Adjust the automatic irrigation controller at least once per month to account for changes in weather.
  • Consider installing a rain shutoff device; at the very least, don’t water when it’s raining.
  • Water deeply for deep root growth.  Use cycle irrigation, with an hour between cycles, to allow water to soak into the soil and reduce runoff.
  • Select sprinklers that water evenly, in a low pattern, and with large droplets.
  • Use a broom rather than a hose to clean decks, patios, and driveways.
  • Wash your car with soapy water from a bucket.  Only use the hose to rinse.
  • Visit the Colorado State University’s Cooperative Extension website for more great tips for getting a green lawn while still reducing water use, including information for watering during drought and/or watering restrictions.

Smart Lawn Watering

For water-wise lawn watering and outdoor water conservation, the City suggests following the lawn watering schedules recommended in the Drought Response Plan and outlined below.

Suggested Voluntary Lawn Watering Schedule

  • Sunday:  Residential (single family and duplexes) EVEN Addresses
  • Monday:  No Watering
  • Tuesday:  Non-Residential (commercial, multi-family, multi-family, homeowner's associations, other)
  • Wednesday: Residential (single family and duplexes) ODD Addresses
  • Thursday:  Residential (single family and duplexes) EVEN Addresses
  • Friday:  Non-Residential (commercial, multi-family, multi-family, homeowner's associations, other)
  • Saturday:  Residential (single family and duplexes) ODD Addresses

Cycle Irrigation 

Longmont's clay soils can only absorb a limited amount of water at one time. Cycle irrigation reduces runoff and allows more water to be absorbed, resulting in deeper root growth and more drought-tolerant lawns.

Cycle irrigation is a lawn-watering approach that uses multiple start times, running through a multiple cycle of zones more than once per day. For example, instead of watering an entire zone for 20 minutes, set up three start times of 6 minutes each for a total of 18 minutes or two start times of 10 minutes each for a total of 20 minutes. Set start times so that there is an hour in between cycles, and adjust the length of time you water each zone so that no runoff occurs.

Don’t Forget Your Trees!

The City of Longmont publishes an informative brochure to guide residents on watering trees during the Fall, Winter, and a drought. 

Businesses Can Conserve, Too!

The Center for ReSource Conservation, a nonprofit partner with the City of Longmont, offers FREE sprinkler inspections in qualifying water districts to businesses and commercial properties.
