According to the U.S. EPA, the average household's leaks can account for more than 10,000 gallons of water wasted every year, or the amount of water needed to wash 270 loads of laundry. If you feel your water use is high, use the online customer water use portal, AquaHawk, to compare your current water use to your past usage and check for common leaks. Common types of leaks found in the home include worn toilet flappers, dripping faucets, and other leaking valves. Some leaks you can easily fix yourself.

Water Usage and Water Leaks

Faucet leak

Water customers are often surprised by the amount of water typical leaks can waste over time. A leaky faucet that drips at the rate of one drip per second can waste more than 3,000 gallons per year. An irrigation system that has a leak 0.031 inches in diameter (about the thickness of the tip of a ballpoint pen) can waste about 6,300 gallons of water per month.

One of the most common leaks reported to the city are toilet leaks. The volume for toilet leaks can vary greatly depending upon the type of leak. Many toilet leaks are even silent, especially if they are toilet flapper leaks. AquaHawk can be used to assist in finding leaks in the home and around the property.

Checking for leaks

Customer water use portal: Sign up for AquaHawk, the City's online customer water use portal to view your hourly water consumption, manage your water usage and set and customize alert setting. For tips on using AquaHawk to assist in finding leaks, download the Using AquaHawk to Assist in Finding Leaks PDF.

Water meter box: Check your meter box for pooling water. Standing water inside the box often indicates there is a leak.

Irrigation systems: Standing water or areas of consistently moist soil can indicate an irrigation or Watersense sprinklerservice line leak. Check the sprinkler head at the lowest elevation of the yard, pooling water can indicate an irrigation valve leak.

Indoor pipes: If you hear water running in your home, but don’t have a tap turned on, you may have a leaky pipe. Hot water is the most common indoor leak, check your natural gas bill to see if there are spikes in usage.

Toilets: Put two-three drops of food coloring in your toilet tank. If after 15 minutes the coloring has dripped into the bowl without flushing, you have a toilet flapper valve leak.

Faucets and showerheads: Check kitchens, laundry rooms and bathrooms for dripping fixtures. If you have consistent drips or streams, you need to tighten your taps. If that does not work, you may have a leak.

Water usage on utility bills: If the water usage on your utility bill is higher than average, you may have a leak in your home or on your property.

Request a water consumption check: The Public Works Utilities and Operations (PWUO) Department provides water consumption checks free of charge. To request a check for your property, email PWWeb@cityofdavis.org or call 757-5686. PWUO staff will check for continuous use at the meter and contact you with their findings. PWUO staff will only check the meter and city infrastructure; any leaks on the customer side of the meter are the customer’s responsibility. 

The City of Davis does not offer refunds or credit for water consumption charges due to water leaks. Water that passes through the City’s water meter is billed to the property owner. It is the property owner’s responsibility to maintain all water infrastructure (pipes, irrigation, valves, etc.) past the City’s meter.

If you see water pooling in or spilling out of your water meter box, please contact Public Works Utilities and Operations before taking further action so that a meter investigation can be conducted.
