State guide
Louisiana
Louisiana’s drinking-water program is housed at the Louisiana Department of Health, and the state’s lead-service-line work is run through LDH’s Bureau of Engineering Services. On the utility side, Baton Rouge Water, Shreveport, and SWBNO all publish clear split-responsibility language, but the exact handoff point differs by utility: meter, property line, or private-side service line.
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
- Louisiana utilities commonly treat the line from the main to the meter or property-line connection as utility-owned, with the owner responsible from the meter or private-side connection to the building, but the handoff point varies by utility.

- Permits for repair or replacement
- Louisiana does not appear to publish one statewide homeowner repair-permit rule on these pages; Baton Rouge says replacement of any water line requires a permit, and Shreveport says no person may repair or renew service pipes without a valid permit issued by the department.
- Assistance programs
- State pages describe major funding for lead-service-line identification and replacement through public water systems, and SWBNO says it wants to replace both public- and private-side lead service lines; no general statewide homeowner private-side grant page was found.

What to do next

- If you are in New Orleans, complete the Right of Entry form if SWBNO needs to inspect or replace private-side lead pipe.
- If work will replace a water line, confirm permit requirements with your city or utility before excavation.
