Lexington homes get water from the City of Lexington, and a leak on the buried line between the meter and the house is usually the owner's repair; the City hasn't published the exact dividing point. With so many homes built before 1980, a plumber will often weigh patching the break against laying a new line. Call the number on this page to be connected with a local plumber in Lexington.

Lexington's water system and its older homes
The City of Lexington runs its own water, sewer, electric and natural gas systems. Water comes from Lake Thom-A-Lex, with City Lake and interconnections to Davidson Water held for emergencies, and moves through more than 192 miles of lines to over 10,000 meters. The City's 2025 report says it is responsible for removing lead pipes and that residents share responsibility for their home plumbing, but it doesn't state where the City's part of a service line ends. For anything at or near the meter, call the City first.
What sets Lexington apart is the age of its housing. The median home was built in 1969, about 68% predate 1980 and roughly 14% predate 1940. In the Uptown, Erlanger Mill Village and residential historic districts, a service line may be original or patched in pieces over the decades. The City keeps a full service line inventory online and at City Centre on N. State Street, and its October 2024 lead sampling put the 90th percentile at 0 ppb. Even so, the private pipe under an old yard is often well past its best years.
Repair or replace?
| Situation | Usual direction | Why |
|---|---|---|
| One crack or bad joint on pipe in good shape | Repair the section | Less digging, and the rest of the line has life left |
| Second or third leak on the same old line | Replace meter to house | More breaks are likely, and each dig costs time and yard |
| Corroded or mixed materials found during the dig | Replace | Joining new pipe to failing pipe moves the problem down the line |
| Driveway or mature trees over the old route | Ask about trenchless or a new path | Pulling or boring a new line can spare the surface |
Signs to look for
- Pressure that fell at every fixture together
- Ground that stays soaked along the path from the meter to the house
- Rusty or discolored water from the cold taps in an older home
- The meter turning with all water off
Timing and the seasons
Leaks in clay soil often show up after a dry spell breaks, when shrinking and swelling ground shifts old pipe. Hard freezes can split shallow sections and the pipe where it enters a crawl space. A slow leak can wait a day or two for a scheduled visit if you can keep the main open safely; a break that floods the yard or leaves the house without water calls for closing the main valve and getting help that day. Permits run through the City of Lexington's online Permit Portal.
