Water Line Leak Between the Meter and the House: Who Pays in Baltimore?
Baltimore City DPW’s Cold Weather Tips say the Department of Public Works maintains outdoor water lines up to and including the meter, and that the line from the meter into the house is the property owner’s responsibility. This guide shows how to tell which side a leak is on using DPW’s own meter test, who to call for each side, what homeowners insurance usually leaves out, and how to claim a bill credit after the repair.
Water bubbling in the street? That side is the utility’s: call 311.
Which side is the leak on?
- Leak in the street, hydrant or meter vault: call 311.
- Leak between the meter and your foundation: call a plumber.
- Leak inside the house: call a plumber.
- High bill with no visible leak: run DPW’s meter test.
Step 1 of 4
Look for round-the-clock water use first
Baltimore City DPW tells customers with a high bill to check their daily use in its Customer Self-Service Portal at waterbillportal.baltimorecity.gov; when DPW launched the portal it noted that use continuing around the clock can point to a broken service line. Without portal access, use EPA WaterSense’s test: read the meter before and after a two-hour stretch with no water running, and any change means a leak.
Step 2 of 4
Close the main valve inside your home
DPW’s leak test starts by shutting off the valve on the main water line where it comes into the home, so every fixture and appliance inside stops drawing water. Where that valve sits in Baltimore homes walks through gate and ball valves.
Step 3 of 4
Watch whether the meter still registers use
If the meter keeps registering water use with the main valve closed, water is escaping between the meter and the house. DPW says that result points to an underground leak on your property, which is the owner’s to repair.
Leave the meter vault itself alone: in Baltimore City the meter and its valves are City equipment, and City Code § 21-6 bars tampering with them without DPW permission.
Step 4 of 4
Call the right party for the side that leaks
- Public side: report water main breaks, leaking hydrants and exterior leaks to Baltimore City 311 (what to do during a water main break covers the steps). For homes outside city limits, follow DPW’s current guidance on its water emergency page, or ask 311 which line applies.
- Private side: a leak on the service line between the meter and your foundation, or anywhere inside, needs a plumber. A leak at the water heater, from its fittings, relief valve or tank, is covered under leaking water heater repair in Baltimore.
A smell of gas is a different emergency: leave the building and call 911 or the gas utility. Gas lines are a separate system, and what a repair runs is in gas line repair cost.
Who owns each part of the water line in Baltimore?
The property owner is responsible for the line from the meter to the house and all indoor plumbing; DPW maintains the public side, though its documents word the dividing point two ways. DPW’s Cold Weather Tips say DPW maintains outdoor lines up to and including the meter, while its Rules and Regulations put the dividing point at the meter vault, or at the property line where no vault exists.
City rules install meters and meter vaults at the curb line nearest the water main unless DPW decides otherwise. Baltimore City DPW and Baltimore County’s public works department also state that part of every residential service line in the regional system is privately owned. Repairing or replacing the private stretch is covered in meter-to-house water line repair and replacement. The sewer lateral divides at the property line too: DPW maintains it from the sewer main to the property line, and the owner is responsible for the rest, as set out under sewer line repair in Baltimore, MD.
Baltimore County homes are billed by Baltimore City, which owns and runs the regional water system; County billing and meter questions go to 410-396-5398, and the County’s first online portal is scheduled for fall 2026.
Can you get a leak credit on your Baltimore water bill?
Yes, once the leak is repaired and you apply within 60 days of the bill. DPW removes all the extra water from an underground leak, and recalculates the sewer charge to match, but only 50% of the extra water from an interior leak such as a running toilet.
| Rule | Underground service line leak | Interior leak (toilet, fixture, appliance) |
|---|---|---|
| Extra water removed | All of it; sewer charge recalculated | 50% (the DPW example shows 100% for senior or hardship customers) |
| Proof required | Licensed plumber’s receipt with the repair date and type of repair | Confirmation that repairs are complete |
| Deadline | Request within 60 days of the bill; the owner or an authorized person applies | |
| How often | Limits apply: DPW’s adjustment page says once every two years for underground leaks and every three years for interior leaks, while its online form says one of each per 12 months | |
| When the credit shows | About 4 weeks after DPW receives the form | |
For a bill review, call DPW Customer Support at 410-396-5398 or email [email protected]. Disputes that stall can go to the City’s independent Office of Water Advocacy & Customer Appeals at (443) 984-WACA; City Code gives customers 90 days after a disputed billing decision to ask for its help and bars requiring payment to anyone, including a plumber, before an appeal is heard.
Does homeowners insurance cover the line from the meter to the house?
Usually not. Baltimore City DPW states that homeowners insurance plans do not typically cover repairs to exterior, underground lines, and that the customer is responsible for all maintenance costs of the water service pipe on their property.
Water damage inside the house from a sudden break is a different question; standard homeowners policies cover sudden and accidental discharge, as the burst pipe first steps explain. Water on the basement floor after a storm, with the meter standing still, is groundwater rather than a service line leak; sump pump drainage and repair covers that case.
What a water service line repair costs
National price ranges for a service line leak repair and a full replacement, and what moves the price on a Baltimore job, are set out on our water line repair and replacement page.
Check the line’s material while it’s exposed
A service line dug up for a leak is the easiest moment to confirm what it is made of. Baltimore City DPW announced in September 2025 that it would mail service line inventory letters and asks owners of unknown lines to report the material; what those letters mean and how to test the pipe covers the key-and-magnet check.
Water line leak questions
Who is responsible for the water line from the meter to the house in Baltimore City?
The property owner. Baltimore City DPW’s Cold Weather Tips say water lines running from the meter to the house, and internal plumbing, are the property owner’s responsibility. DPW’s Rules and Regulations place the dividing point at the meter vault, or at the property line where no vault exists.
How do I know if I have an underground water leak?
Close the main water valve inside your home and watch the meter. Baltimore City DPW says that if the meter still registers use with the main valve closed, there might be an underground leak on your property.
Can I get money back on my water bill after fixing a leak in Baltimore City?
Yes, within limits. Apply to DPW within 60 days of the bill. An underground leak repaired by a licensed plumber gets all extra water removed; an interior leak gets 50% removed. Credits appear about 4 weeks later.
Who do I call about water bubbling up from the street?
Call Baltimore City 311 to report water main breaks, leaking hydrants or exterior leaks. Homes in the Baltimore County service area should follow DPW’s current guidance, and 311 can point you to the right line.
Get the private-side leak fixed
Once the meter test points to your side of the line, the leak needs locating and the damaged section replaced. The 24/7 Baltimore emergency plumbers in our network handle service line leaks around the clock; see our Baltimore water service line repair page.
