State guide
South Carolina
South Carolina’s drinking-water program is run by the South Carolina Department of Environmental Services, which publishes both a general drinking-water program overview and a specific Lead & Drinking Water page. I did not find a statewide ownership rule on the state pages reviewed; the large utility pages I found generally place utility responsibility through the meter and homeowner responsibility from the meter to the house.
Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.
- Who usually owns the water service line
- No statewide ownership split was found on the SCDES pages reviewed; the large utility pages found for Charleston, Greenville, and Columbia all put homeowner responsibility on the line after the utility meter.
- State drinking water program
- South Carolina Department of Environmental Services, Drinking Water Protection Program.
- Permits for repair or replacement
- Local rules vary; on Charleston Water’s lead replacement project form, Charleston Water says it will obtain necessary permits for the replacement work.
- Assistance programs
- Charleston Water says it will replace eligible lead service lines at no charge under its state revolving fund lead service line replacement project; Columbia also endorses optional exterior service-line protection plans.

What to do next

- Before paying for a private leak repair, confirm whether your utility’s responsibility ends at the meter or another utility-owned point on the official utility page.
- If you are in Charleston Water territory and have a lead line notice, check whether you qualify for the utility’s no-charge lead service line replacement project.
