The city is responsible for a water meter leak when the leak sits on the utility’s side of the system, which in most places means the water main, the service pipe running from the main to the meter, and the meter itself. Once water passes the meter’s outlet fitting, the pipe and everything downstream belong to you. The exact boundary varies by utility, so the first job is figuring out which side of that line your leak falls on.
Where the Utility’s Responsibility Ends and Yours Begins
Every property has a service line running from the water main under the street to the house. Somewhere along that line, ownership shifts from the utility to the homeowner. In most communities, the meter marks that transition: the city owns and maintains everything from the main through the meter, and you own everything from the meter’s outlet to the house.
That split is not universal. Some utilities draw the line at the curb stop valve, a shutoff buried near the property line or sidewalk. In those systems, you own the pipe from the curb stop through the meter and on to the house. A smaller number of utilities own the full service line from main to building, and others place the whole line in the homeowner’s hands. Your utility’s service agreement or website spells out exactly where its responsibility ends. If you can’t find it, call the water department and ask.
The practical effect is the same wherever the line is drawn. Leaks on the utility’s side get fixed at the utility’s expense. Leaks on your side get fixed at yours.
How to Tell Which Side the Leak Is On
Before you call anyone, you can usually narrow things down in about ten minutes. Shut off every water-using fixture and appliance in and around the house, including ice makers and irrigation.
Find the meter, usually inside a concrete or plastic box near the curb. Most meters have a small triangular dial or a spinning silver wheel known as a low-flow indicator. With all water off, watch that indicator for two to three minutes. If it moves, water is flowing through the meter and the leak is somewhere downstream.
To tell whether that downstream leak is in the buried pipe between the meter and the house or inside the house, close the main shutoff valve where water enters the building. Check the indicator again. If it stops, the leak is inside. If it keeps moving, the leak is in the buried pipe between the meter and the foundation. That second scenario is the expensive one.
If water is pooling around the meter box itself, bubbling up in the street or sidewalk, or surfacing near a fire hydrant, the leak is almost certainly on the city’s side. Skip the test and report it.
Reporting a Leak on the City’s Side
When the leak appears to be on utility infrastructure, call the water department or public works division. Most utilities run a 24/7 emergency line for leaks and main breaks, and many also take reports through 311 or an online service request portal.
Have your account number and service address ready. Describe what you’re seeing: water flowing from the meter box, a wet spot in the street or right-of-way, pavement buckling, water surfacing near a hydrant. If you ran the meter test and the indicator kept moving with your main shutoff closed, say so. That detail helps the dispatcher prioritize.
A technician will come confirm the location and severity. Emergencies where water is flooding or undermining a road usually get same-day attention. Smaller seeps may be scheduled anywhere from a few days to several weeks out depending on the utility’s backlog. Keep the reference number so you can follow up if the repair stalls.
When the Leak Is on Your Side
If testing points to the buried pipe between the meter and the house, the repair typically runs anywhere from a few hundred dollars for a simple joint fix to several thousand for a full service line replacement. Cost depends on the pipe’s depth, its material (older galvanized steel and polybutylene are more prone to failure), the length of the run, and whether the work requires cutting through concrete, driveways, or landscaping.
Before any digging, federal law requires you to contact 811, the national “Call Before You Dig” line, at least a few business days before excavation. The one-call system notifies utilities with buried infrastructure near your property so they can mark their lines. Under federal law, anyone excavating in a state with a one-call notification system must use that system first to locate underground facilities in the work area.1Office of the Law Revision Counsel. 49 U.S. Code 60114 – One-Call Notification Systems Hitting a gas line or fiber optic cable because you didn’t call can result in fines, repair liability, and injury.
Most homeowners hire a licensed plumber for this work. Get at least two or three quotes, because underground estimates vary widely. Ask each plumber whether they’ll restore landscaping and hardscape they disturb; some include that and some don’t.
Getting a Bill Adjustment After a Hidden Leak
A hidden leak can waste thousands of gallons before you spot it, and that water shows up on your bill. Many utilities offer a leak adjustment program that credits back part of the excess, but the rules are strict.
The most common requirement is proof that the leak has been repaired. Utilities want a dated invoice from a licensed plumber or, for DIY work, receipts for parts along with a description of what you fixed. You typically have to submit within a set window after the high bill, often 30 to 120 days depending on the utility. Miss the deadline and you usually get nothing.
Most programs will not make you whole. The standard formula takes the difference between your normal usage and the inflated bill and credits roughly half of that excess. You pay your normal amount plus half the overage. Some utilities are more generous, others less. Nearly all limit adjustments to once every 12 or 24 months, so a second leak in the same period won’t qualify.
Check the utility’s website for a leak adjustment form or call and ask. Fill it out completely, attach your repair documentation, and keep copies of everything.
Insurance and Service Line Coverage
Standard homeowners insurance does not cover underground service line repairs. The policy likely covers sudden water damage inside the home, such as a burst pipe flooding a finished basement, but the buried line running from the meter to the house sits in a coverage gap.
Two options fill it. The first is a service line endorsement added to your homeowners policy. These riders typically cost less than $5 a month and provide around $10,000 in coverage for repairing or replacing damaged buried utility lines, including water, sewer, gas, and electrical. They usually cover damage from corrosion, tree root intrusion, freezing, and normal wear, which are the failures standard policies exclude. A deductible applies, often around $500.
The second option is a standalone service line protection plan, typically offered by a third-party company that partners with your local utility. These plans appear as a small monthly charge on the water bill, usually in the $5 to $17 range depending on what lines are covered. They work like a warranty: if a covered line fails, you call the plan provider and they send a contractor.
Either option is worth considering if the home is more than 20 or 30 years old, if mature trees sit near the service line, or if the area has clay or galvanized steel pipes known to deteriorate. A single underground repair can easily exceed what you’d pay in premiums over a decade.
When the City May Owe You for Damage
If a water main break or a leak on the city’s side floods your property, damages your foundation, or destroys landscaping, you may be able to recover those costs, but recovery is not automatic. Cities carry legal protections that private companies don’t.
Courts in most states treat a city’s operation of its water system as a proprietary function, meaning the city is held to the same standard of care as a private water company. There is no blanket immunity simply because the operator is a government entity. You still have to show the city was negligent, which usually means proving it knew or should have known about a problem and failed to act with reasonable care.
The strongest claims involve notice. If you reported a leak weeks ago and the city ignored it, and the line then burst and flooded your basement, that delay creates real liability. If a main breaks without warning and the city responds promptly, courts are far less sympathetic.
Document everything right away: photograph the damage, note the date and time, save any communication with the water department, and get written repair estimates. Most municipalities require a formal tort claim within a short window, often 30 to 90 days, before you can sue. Missing that deadline can bar the claim entirely regardless of how strong the evidence is. The city clerk’s office or risk management department can provide the claim form and the filing deadline.
When you’re not sure whose side a leak is on, report it to the utility anyway. The utility will investigate and tell you, and you’ll have a record showing you acted promptly, which matters if you later need a bill adjustment or a damage claim.
