Charlotte Water draws a clear line at the meter. Here is what the utility owns, what the property owner owns, how to tell which side a leak is on, and when the service line is worth replacing with a repipe.
Last Updated:
Short answerThe property owner is. Charlotte Water owns the main, the meter, the meter box and the line from the main to the meter. The owner owns the tail piece, the shut-off valve, the service line from the meter to the house and all interior plumbing, so leaks on that side are the owner's to repair.
Who is responsible for the water line from the meter to the house in Charlotte? The property owner. Charlotte Water owns the system up to and including the meter, and everything on the house side of it belongs to the owner. Level Repiping Charlotte arranges water line replacement and interior repipes across Charlotte and the surrounding counties through licensed and insured contractors. This guide sets out the ownership split, explains how to tell which side a leak is on, and covers when the service line is worth replacing at the same time as the pipes inside.
Charlotte Water serves all of Mecklenburg County, and it describes the split this way on its Lead Free CLT page:
| Part of the system | Owner |
|---|---|
| Water main in the street | Charlotte Water |
| Fire hydrant and hydrant line | Charlotte Water |
| Service line from the main to the meter | Charlotte Water |
| Meter and meter box | Charlotte Water |
| Tail piece and shut-off valve on the house side of the meter | Property owner |
| Service line from the meter to the house | Property owner |
| All interior plumbing | Property owner |
The meter box is the boundary. In most Charlotte neighborhoods it sits near the street or sidewalk, and the owner’s line runs underground from there to where it enters the house, usually at a crawl space wall, a garage or a utility closet.
North Carolina’s plumbing code amendments call the underground run the water service pipe. It runs from the main, or from the meter where the meter sits at the right of way, to the building, and the code treats it as ending 5 feet outside the foundation wall, where the water distribution system inside the house takes over. The amendments require water service pipe to meet NSF 61 for drinking water, carry a listing, and handle at least 160 psi at 73.4°F. Exterior water supply pipe must be buried at least 12 inches below grade and at least 6 inches below the frost line.
Those rules matter when the line is replaced. Some materials that are fine underground are not approved inside a house, so the code makes them stop outside the foundation, at or before the full-open valve where the line enters.
Charlotte Water says leaks inside a building or between the meter and the building are the customer’s to repair with a plumber, and that the leading cause of a high water bill is a private plumbing leak: running toilets, dripping faucets, irrigation and old plumbing. The utility repairs leaks on its own side, almost 4,000 in a single year by its own count. After a private leak is repaired, Charlotte Water says it has resources to help with the outstanding balance, so it is worth asking the utility once the repair is done.
A simple test narrows it down:
Wet ground, a soft spot in the lawn or a sinkhole along the path from the meter to the house points to the service line. A leak inside a slab house that never shows on the surface can be under the floor; the slab leak signs guide covers that case.
The main shutoff is the valve that stops water to the whole house. In Charlotte houses it is usually where the service line enters, in the crawl space, the garage or near the water heater, with a second shutoff at the meter on the owner’s side. Old gate valves seize, and a shutoff that won’t close fully turns any plumbing problem into a bigger one. Replacing a worn main shutoff is a common part of a whole house repipe and of a service line replacement.
Interior repiping and service line replacement are different jobs. A repipe works inside the house through crawl spaces, attics and walls. Service line replacement is underground, from the meter to the foundation, and it is usually done by trenching or by pulling a new line through the path of the old one, depending on the yard.
They are often done together because the old pipe is often the same. A house with polybutylene inside frequently has a polybutylene service line too, and older houses can have galvanized steel underground. Of the 81 Mecklenburg plumbing permits from April 2025 to October 2026 that describe a repipe, 12 also include water service work. Doing both at once means one shutdown and one set of fittings at the foundation. The service line is still a separate run with its own price, so it should appear on its own line in the estimate. The repipe cost guide shows how it fits among the other price drivers.
A related case is a house moving from a private well to city water. About 40 Mecklenburg plumbing permits since 2024 describe abandoning a private well and connecting to a city tap with a new service line. The well line replacement page covers well systems.
Charlotte Water’s service line inventory lists no lead service lines and 66 galvanized lines that require replacement. Its Lead Free CLT program publishes a searchable map of service line material by address. The lead and galvanized service lines guide explains what the inventory means and how to read the map.
Other utilities in the region set their own rules, and the meter split can differ in detail, so it is confirmed per address:
If the line from the meter is old, leaking or a known material such as polybutylene, the water line replacement page explains how the run is replaced. To talk through your line, call (704) 452-4386.
Questions
Charlotte Water. The utility owns the main, the line from the main to the meter, the meter and the meter box. If water is surfacing near the street or the meter box itself, report it to Charlotte Water. A leak on the house side of the meter is the property owner's.
The homeowner's. Charlotte Water lists the tail piece and the shut-off valve on the house side of the meter as customer-owned, along with the line to the house. If that valve is stuck or leaking, replacing it is the owner's job, and it is often done when the service line is replaced.
Often, yes. A polybutylene or galvanized service line fails for the same reasons as the pipe inside, and replacing it while the house is already being repiped avoids a second shutdown later. It is a separate underground run with its own price, so it appears as its own line on the estimate.
