State guide
Indiana
Indiana does not have one single ownership split statewide: utility rules I found vary sharply by city and provider. IDEM’s lead page requires inventorying all service lines, including utility and customer portions, and IDEM guidance says it does not endorse partial lead service line replacement.
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 default split was found; Indiana utilities vary, with examples ranging from utility ownership to the curb stop, utility responsibility only to the public right-of-way, or customer ownership of the full service line from the main connection to the building.

- Permits for repair or replacement
- Indiana state pages reviewed did not give one statewide homeowner permit rule, but local utility rules can: Citizens requires a water service application permit for repair, modification, or new service-line work by a bonded plumber or contractor.
- Assistance programs
- Citizens says designated project-area replacements are done at no additional cost to the homeowner, Fort Wayne offers free replacements in some federally funded neighborhoods and financing or low-income help elsewhere, and Lafayette says its current program replaces identified lead service lines at no cost to customers.

What to do next
- Do not assume the public/private split in Indiana; read your utility’s own rules for your address before authorizing excavation or leak repair.
- If you are in Citizens or another utility territory with a lead-replacement program, check whether joining the utility project is cheaper than hiring your own contractor.
- Ask whether your utility requires its own permit, bond, inspection, or approved plumber list before private-side work begins.
