Reducing Water Usage in Boulder

The Water Conservation Program offers support services to City of Boulder customers who want to be more efficient with their water use. Using water efficiently and eliminating leaks can help reduce your water utility bill while also supporting the Boulder community to be more sustainable.

Did You Know?

Nearly one trillion gallons of water are wasted each year in U.S. homes in preventable ways. The average household leaks almost 10,000 gallons of water per year, or the amount of water it takes to wash 300 loads of laundry.

In just 10 minutes, you can search your home for leaks and crack down on water waste.

Many common household leaks are quick to find and easy to fix!

Water Conservation Best Practices

Find a Water Leak

In the Home

  1. Toilets

    Listen for running water and conduct the food coloring test. Put a few drops of food coloring into the tank at the back of your toilet and let it sit for 10 minutes. If color shows up in the bowl, you have a leak.

  2. Sinks

    Look and listen for drips from the faucets or in the pipes under the sink.

  3. Showerheads

    Look for a dripping showerhead and replace with a new one, if needed.

  4. Bathtub

    Turn on the tub, then divert the water to the shower and see if there’s still a lot of water coming from the tub; that could mean the tub spout diverter needs replacing.

  5. Sinks

    Check for pooling water under pipes and rust around joints and edges.

  6. Clothes washer or dishwasher

    Look for pooling of water under pipe connections, rust or other signs of leakage.

Outside the Home

The City of Boulder provides free irrigation consultations through Resource Central that can help you identify obvious leaks in your irrigation system.

  1. Spigot

    Ensure tight connections with the hose and see if the hose washer need replacing.

  2. Irrigation system

    Check for broken sprinklers or nozzles spraying in the wrong direction.

Outdoor Water Tips

There are many ways to reduce water outdoors and to be smart with your landscape. You can create your yard to promote pollinator habitat or reduce pollutants from entering our local waterways! Follow these eight water conservation tips.

Wait to Water image

Don't turn on the sprinklers too early in the season. Leaving lawns dormant longer will save water, and will not compromise the longevity of your lawn. April is too early to go automatic, plan on programming your sprinkler system to start in May or June. Hand-water trees and plants as needed - trees offer many benefits such as shade and habitat, and are often greatly impacted by drought, so keep an eye on the health of your trees and water them when needed.

Water Less Frequently Icon

Check with your water supplier for water use rules. Watering twice a week will make grass roots grow deeper and allow the grass to last longer without water. Cycling sprinkler system run times can prevent excess water runoff; visual inspections after an initial watering cycle will make this apparent. An example of a better watering schedule is setting each zone to water for five minutes then wait an hour, water for five minutes again, wait one more hour, then water for a final five minutes. This breaks up the 15 minutes of watering into three cycles, allowing the water to have time to absorb into dense and compact soils.

Watering Hours Icon

Watering landscapes in the early morning or at night will help reduce water loss. During the daytime heat, less water will be available to plants due to loss from evaporation and wind. Please check your local water provider for current water restrictions, including watering hours.

Don't Water When It's Raining Icon

Watch the weather and adjust watering days and times accordingly. Use soil moisture sensors or rain sensors to automatically adjust watering schedules when it rains. Consider installing a WaterSense Smart Irrigation Controller. Check with your water supplier for potential rebates on irrigation equipment and other opportunities.

Let Grass Grow icon

Raise lawn mower blades and protect lawns from heat by letting grass grow longer (3 - 3.5 inches). A taller lawn provides shade to the roots and helps retain soil moisture, so your lawn requires less water.

Water Plants not Roads icon

Check to see if your irrigation heads are broken, tilted or not set-up properly by scheduling an irrigation assessment. Sweep driveways and sidewalks with a broom instead of spraying with a hose - but please not down the storm drain or into the street gutter. Use hand-watering, deep root water, or drip irrigation for trees, shrubs, bushes, perennial beds, annual flowers and vegetable gardens. Always use a shut-off nozzle on your hose when watering plants.

Fix Irrigation Leaks image

Check your sprinkler system monthly for broken sprinkler heads and damaged irrigation lines. Hire a professional to conduct a sprinkler assessment - check with your water supplier, many have low cost or no cost sprinkler assessment programs for their community. A well maintained system will save both money and water.

Plan Efficiently Icon

If possible, delay new lawn installations for a non-drought year and avoid planting during the mid-summer heat. If you've already purchased a water wise garden this year, plant early in the morning or evening in May. Incorporate water wise plants and turf when planning landscape renovations or installations.

Conservation Tips for Businesses

  • Restaurants should only serve water when asked.
  • Have your system checked for leaks and get them repaired.
  • Teach water awareness to employees.
  • Use one glass per employee per day to cut down on dirty dishes.
  • Install toilet dams or displacement devices to cut down on the amount of water needed for each flush. Put an inch or two of sand or pebbles in the bottom of a quart or larger container and fill the rest of the container with water. Put the cap on and place the bottle in your toilet tank, safely away from the operating mechanism. The container will save on each flush without impairing the efficiency of the toilet.
  • Check your toilets for leaks. Put a few drops of food coloring in the tank. If the coloring begins to appear in the bowl without flushing, you have a leak that should be repaired immediately. Even a small leak can waste thousands of gallons.
  • Install low-flow shower heads in shower facilities.
  • Use high-efficiency equipment and appliances.
  • Don't use or install ornamental water features unless they recycle water.
  • Start a conservation program.
  • Know where your water gets used. It is important to know how much water is being used for each of your firm's industrial processes and/or domestic needs. Monitor your water bills to see how you're doing.
  • Get your business PACE certified! PACE (Partners for a Clean Environment) recognizes businesses that implement conservation methods.
