Charlotte Water has classified every one of its service connections. Here is what the inventory says about lead and galvanized lines, what Lead Free CLT does, how to look up your address, and where lead can still hide inside a house.
Last Updated:
Short answerCharlotte Water's inventory of 333,871 service connections lists no lead service lines. It lists 66 galvanized lines that require replacement, mostly in central and inner-ring Charlotte. Through Lead Free CLT, the utility publishes a searchable map of service line material and replaces qualifying lines. Plumbing inside the house remains the owner's.
Lead service lines in Charlotte are rare enough that Charlotte Water’s inventory counts none. The utility has classified every one of its 333,871 service connections, and the open question for a few dozen homes is galvanized steel, not lead. Level Repiping Charlotte arranges galvanized pipe replacement, service line work and whole house repipes across Charlotte and the surrounding counties through licensed and insured contractors. This guide explains what the inventory shows, what Lead Free CLT does, how to check your own line, and where lead can still come from inside a house.
Federal rules required water systems to inventory the material of every service line. Charlotte Water’s public inventory reports:
| Classification | Service connections |
|---|---|
| Total service connections | 333,871 |
| Non-lead | 333,805 |
| Galvanized requiring replacement | 66 |
| Lead | 0 |
On the private side, the part the owner owns from the meter to the house, the inventory classes 333,736 lines as non-lead copper, 69 as non-lead plastic and 66 as galvanized. Of all connections, 202,101 are classed as non-lead from records or inspection and 131,704 as predicted non-lead. A predicted classification comes from building age, records and modeling rather than someone looking at the pipe, which is why a look at your own line still has value.
The 66 galvanized lines are mostly in central and inner-ring Charlotte, the city’s oldest neighborhoods, with a few in south and east Charlotte and two near Lake Norman.
A galvanized steel line is not lead. It lands on the replacement list because of what may have been upstream of it. Before lead pipe was banned, some houses had a short lead connector or lead line between the main and a galvanized service line. Lead particles from upstream can collect in the rough, rusty scale that builds up inside galvanized pipe and be released later. That is why federal rules treat galvanized lines that are, or ever were, downstream of a lead line as needing replacement, and why Charlotte Water describes its program as removing galvanized lines previously downstream of lead.
Galvanized pipe has its own problems apart from lead. It rusts from the inside, the bore narrows, flow drops and the water can run brown after it sits. Those are reasons to replace it whether or not it is on the list. The galvanized pipe replacement page covers that work inside the house.
Charlotte Water’s Lead Free CLT program has four parts:
Replacement is utility-led. Charlotte Water selects homes using its modeling, prioritized by building age and community need, and contacts owners by letter or visit. It is not a rebate a homeowner applies for, and it does not cover interior plumbing. Charlotte Water says property owners are responsible for internal plumbing, faucets and fixtures.
Charlotte Water calls Charlotte a relatively young city, with most of its growth after the 1986 federal ban on lead pipe, solder and flux in drinking water plumbing. Census figures back that up: the median home in the city was built in 1995, and only about 10% of its housing predates 1960. Most service lines went in after lead was out of use.
The utility also manages its water to limit corrosion. Charlotte Water adds lime to raise the pH, which it says helps prevent pipe corrosion and the leaching of metals, and the state has set a pH range for its system for corrosion control. In its most recent annual water quality report, lead and copper were below detection at the 90th percentile of tap samples, with one site above the 15 ppb lead action level.
Start with the map: search your address on Charlotte Water’s service line map and note how your private side is classed.
Then look at the pipe where it enters the house, usually at the main shutoff in the crawl space, garage or utility closet. The U.S. Environmental Protection Agency’s quick check uses a magnet and a coin:
| What you see | What it usually is |
|---|---|
| Copper color, like a penny | Copper |
| Dull gray; a magnet sticks | Galvanized steel |
| Dull gray, soft; scratching shows shiny silver; a magnet does not stick | Lead |
| White, black, blue or gray plastic | Plastic, such as PVC, polyethylene or polybutylene |
Scratch gently, and only on the pipe itself, not on a fitting. If the result disagrees with the map, or you can’t tell, the identify your pipe material guide has more photos and clues, and an assessment can confirm it.
A lead-free service line does not mean a lead-free house. Before the 1986 ban, copper pipe was often joined with lead solder, and some older faucets and brass fittings contain lead. Those sources sit inside the house, on the owner’s side, and Lead Free CLT does not address them. Replacing old copper and fixtures during a whole house repipe removes both. Testing water from a specific tap is the way to know what reaches the glass.
Neighboring utilities have done their own inventories:
If your service line is galvanized, or the map and the pipe disagree, the lead service line replacement and water line replacement pages explain how the run from the meter is replaced, and the water line ownership guide explains which part is yours.

Questions
Charlotte Water's Lead Free CLT program publishes a searchable map of private service line material. Search your address and it shows how your side of the line is classified, for example non-lead copper, non-lead plastic or galvanized. A predicted classification comes from records and modeling, so checking the pipe where it enters the house adds certainty.
Not by itself. The concern with galvanized lines is that ones which sat downstream of a lead line can hold lead in their rusty inner scale. Charlotte Water's inventory flags 66 such lines for replacement. Its tap sampling found lead below detection at the 90th percentile, though one site was above the 15 ppb action level, so testing a specific tap is the way to know.
No. Lead Free CLT removes lead service lines and galvanized service lines that were downstream of lead, at homes Charlotte Water selects. Charlotte Water says property owners are responsible for internal plumbing, faucets and fixtures, so pipe inside the house is the owner's to replace.

Galvanized pipe replacement in Charlotte: why old steel pipe loses flow and runs brown, how it is tested, and how a repipe runs in older homes.
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.
Five supply pipes turn up in Charlotte-area houses. Color, joints, markings and a magnet tell most of them apart in a few minutes, as long as you look in more than one place.
The three supply pipes found in older Charlotte-area houses, how each one was meant to work and how it fails, the signs that point to the pipe rather than something else, the rules and insurance questions around replacement, and what each scope leaves behind.
Both are approved under the North Carolina Plumbing Code. The house, the routes the pipe has to take and what the owner values decide between them, not a rule of thumb.
One leak on sound pipe is a repair. A pattern of leaks, or a pipe with a known failure history, is a question about the whole system. The evidence that separates the two is usually in the house.
