State guide
Maine
Maine’s primacy agency is the Maine CDC Drinking Water Program, which has detailed lead-service-line inventory guidance and state funding pages. Utility responsibility in Maine is often split at the curbstop or curb valve near the property line, but local tariffs and utility rules control the exact boundary.
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
- In Maine, a common utility split is utility ownership from the main to the curbstop or curb valve near the property line, with the owner responsible from there into the building, but utility-specific rules govern.

- Permits for repair or replacement
- No single statewide homeowner repair-permit rule was found on these pages; Bangor Water says all new service lines and service line renewals require a Project Application prior to construction.
- Assistance programs
- Maine publishes Drinking Water State Revolving Fund and lead-in-service-line funding for public water systems, plus inventory assistance grants; no general statewide homeowner private-side replacement grant page was found, and Maine Water instead offers an optional Linebacker® protection plan.

What to do next
- Ask your utility for its tariff or customer-rights sheet; Maine systems often split responsibility at the curbstop or curb valve.
- Before replacing or renewing a service line, ask the utility whether a project application or utility approval is required.
- If your utility found lead, GRR, or unknown material, ask whether it has state-funded replacement work planned.
