Expensive Water Bill? Expert Gives Tips on Ways to Cut Your Home Use and Save Money

Water bills can be a big expense for many people, so we spoke with a water efficiency expert about ways to cut down on your water use in every part of your home.

Krista Guerrero with the Metropolitan Water District says the first thing you should do is to check for leaks in your home.

Leaks can be a major drain on your bank account and officials say the first place to look is inside your bathroom. Guerrero said the top water-wasting culprit is your toilet but there’s a simple way to check for a leak.

Spruce Up Your Sprinklers in April

Californians gave their irrigation systems the winter off in much of 2023 thanks to above-average precipitation. As the weather warms, the U.S. EPA encourages everyone to perform a maintenance check in April as part of its “Sprinkler Spruce Up” effort.

Annual Leak Detection Program Gets Underway in Otay Water District

As part of its annual preventative maintenance program to safeguard its water supply and reduce water loss, the Otay Water District will conduct leak inspections of its pipeline system beginning January 30. Inspections are expected to continue until April 28.  The District’s contractor, Utility Services Associates, will inspect approximately 171 miles of potable water mains in Spring Valley and Jamul, along with potable and recycled water mains in areas of Chula Vista.

Minor water leaks account for more than a trillion gallons of water wasted each year in homes across the United States. According to the EPA Fix-A-Week-Leak website, each average household with unaddressed leaks can account for 10,000 gallons of water loss every year, enough to wash 300 loads of laundry.

Since 2013, the proactive Leak Detection Program has identified 292 leaks that have been repaired by the District, resulting in an average annual savings of $54,000 per year from reduced water losses. Graphic: Otay Water District leak prevention

For example, the EPA reports a leak just one-32nd of an inch in diameter (about the thickness of a dime) can waste 6,300 gallons of water per month.

Since 2013, the proactive Leak Detection Program has identified 292 leaks that have been repaired by the District, resulting in an average annual savings of $54,000 per year from reduced water losses.

“The Otay Water District conducts inspections annually in different communities we serve,” said Otay System Operations Manager Jake Vaclavek. “It is more critical than ever to insure we are not wasting water as we cope with our state’s ongoing megadrought.”

Customers may see workers inspecting the meter in front of their home or business, typically between 7 a.m. and 5 p.m., Monday through Friday. Weekend and night work may also be required. Inspections can range from a few minutes to a full day.

Inspection workers will wear a Utility Services Associates logo and carry company identification. They will not need access to the homes or property of customers. They may contact customers if they need to momentarily shut off their water supply for further testing. Water supply will not be shut off without permission from someone at the home or property.

Workers might lift water meter covers, inspect, and attach equipment to meters or valves. If they suspect a leak, the Otay Water District will contact the customer and advise them of the potential leak.

Invest In Water Conservation During Fix a Leak Week 2022

Fix a Leak Week is a time to check indoor and outdoor plumbing systems for leaks. This year’s reminder about water conservation comes as California and much of the U.S. Southwest are in the third consecutive year of drought.

Minor water leaks account for more than one-trillion gallons of water wasted each year in homes across the United States. One-trillion gallons equals 3.068 million acre-feet, nearly enough water to meet the needs of San Diego County for seven years.

Fix a Leak Week started in 2009 by the Environmental Protection Agency’s WaterSense program to educate water users and promote the importance of repairing leaks to conserve and protect the water supply.

The week highlighting water conservation is supported by regional WaterSense partners throughout North America, including the San Diego County Water Authority, its 24 member agencies and water agencies throughout the country.

Fix a Leak Week 2022 resources

The Water Authority won its third WaterSense award for Excellence in Collaboration and Promoting WaterSense Labeled Products in 2021.

The Water Authority also partnered with San Diego Gas and Electric to install nearly 4,000 WaterSense labeled showerheads for residents in the area and helped residents save water outdoors through its WaterSmart Contractor Incentive Program, which installed more than 1,000 WaterSense labeled irrigation controllers to achieve six million gallons in water savings

Repairing a leaky toilet can save up to 500 gallons of water a day. In just a month, that’s enough to fill a backyard swimming pool.

The Vallecitos Water District and City of San Marcos are partnering to provide Fix a Leak resources to its customers, including a new website, bill statements, and a demonstration video. It features San Marcos Mayor Rebecca Jones showing a simple method for detecting a toilet leak.

The Sweetwater Authority will participate in Fix a Leak Week 2022, offering tips for consumers and rebates of up to $75 for leak repairs made through June 30. See its website for details and an application. Sweetwater customers can schedule a free water audit by calling the Water Efficiency Hotline at 619-409-6779 or email

Common water leaks such as leaky showerheads or dripping faucets are often easy to fix, requiring common tools and hardware that can pay for themselves in water savings. How much? According to the EPA Fix a Week Leak website, each average household with unaddressed leaks can account for 10,000 gallons of water loss every year, enough to wash 300 loads of laundry.

Investing just 10 minutes to perform a quick search of your home and fixing them can save an additional 10% on your water bill.

Take Ten Minutes to Track Down Leaks During Fix-A-Leak Week 2020

Easily fixed water leaks in American households account for nearly one trillion gallons of water wasted annually. The average household leaks nearly 10,000 gallons of water every year. This would wash 300 loads of laundry and could cost you an additional 10% on your water bill.

Fix-A-Leak Week 2020 is March 16-22. It was created by the U.S. Environmental Protection Agency and is supported by WaterSense partners across the U.S. and Canada, including the San Diego County Water Authority and many of its 24 member agencies.

The Sweetwater Authority will join other water agencies in California, Texas, and Oregon for a Fix-A-Leak Week 2020 “Twitter Party” to help consumers virtually with tips on tracking down leaks and other ways to save water.

In 2019, “leak detectives” across the U.S. put their tools, checklists, and dye tablets to work in bathrooms, kitchens, at faucets and spigots around their homes and joined EPA in the annual Fix a Leak Week by donning their leak detective hats and grabbing their sleuthing gear to find and fix common household leaks. Leaks were detected and fixed in bathrooms – toilets, showerheads and faucets, outside at spigots and in many other locations.

It takes just 10 minutes to perform a quick search of your home for leaks. Many of the most common leaks are easy for anyone to fix such as worn-out toilet flappers, leaky showerheads, and dripping faucets. They require basic tools and hardware.

Here are a few handy tips for finding leaks:

  • Check your water meter before and after a two-hour period when no water is being used. If the meter changes at all, you probably have a leak.
  • Identify toilet leaks by placing a drop of food coloring in the toilet tank. If any color shows up in the bowl after 10 minutes, you have a leak. Flush immediately after this to avoid staining the tank.
  • Turn on your shower and look for drips or stray sprays you can stop with tape.
  • Under sinks, check for pooling water under pipes. Look for rust around joints and edges caused by leaking water.
  • Check under your water heater tank for pooling water, rust, or other signs of leaks.
  • Check all spigots outside. Fixing a leak might be as simple as securing the hose connection, or replacing a worn-out washer.

Find more guides and videos you might find helpful in finding and fixing leaks on the EPA’s “Fix-A-Leak Week” website.

Helix Water District, Sweetwater Authority Offer Smart Leak Detector Rebates

The Helix Water District has rolled out a new smart leak detector rebate program. Helix and Sweetwater Authority customers can get a rebate of up to $100 when they purchase a smart leak detector.

The detectors sync to smartphones, allowing customers to monitor water use 24/7 via smartphone and the devices notify customers of leaks and water consumption amounts.

Smart Leak Detectors

There are two types of smart leak detectors: plumbed devices and external devices, according to Helix.

  • Plumbed Devices
    Plumbed devices are plumbed into your existing water lines. Most of these devices can automatically shut the water off at their point of installation, or allow you to shut your water off remotely, in case of a leak. Since these devices tap into your existing plumbing system, a licensed plumber and permit may be required for installation. Plumbed devices are typically more expensive than external devices.
  • External Devices
    External devices attach to the outside of your water meter, typically with some type of strap, making them simple to install. Since external devices are not directly attached to your plumbing system, they do not have the ability to automatically shut off your water, or allow you to shut off your water remotely, if a leak occurs. External devices are typically less expensive than plumbed devices.

Measure All of Your Water Use

To monitor indoor and outdoor water use, install the leak detector before the point where your irrigation line branches off. This way, the device can alert you of faulty irrigation programming, broken sprinklers or outdoor leaks. This is important, because outdoor use is about half of a typical home’s total water use.

To monitor indoor water use only, install a smart leak detector on your water service line after the point where your main irrigation line branches off.

Rebates are first come, first served

Rebates are available on a first-come, first-served basis and are not guaranteed. To be eligible for this rebate pilot program you must be a customer of either Helix Water District or Sweetwater Authority and purchase a qualifying device on or after August 1, 2019.

Questions? Customers of Helix Water District can contact Helix staff at 619-667-6226 or ; customers of Sweetwater Authority can contact Sweetwater staff at 619-409-6779 or .
