What drives the price in New Hampshire
- Length of the line from the curb stop to the house, and whether the meter is inside.
- Depth. Service lines in New Hampshire are buried below the frost line, often five feet or more, which means deeper pits and more digging than in warm states.
- Trenchless or open trench. Pulling a new pipe through the old path from two small pits usually costs less to restore than a full trench.
- Permits and the public side. Some cities charge permit and street-opening fees, and a few make the owner pay to cut the street.
- Restoration of lawns, driveways, sidewalks and basement walls, which free programs often limit.
New Hampshire has no law we found that decides who pays for the private side of a lead service line, so each utility sets its own policy. Under the federal rule, utilities must replace every lead line and galvanized line that needs it within ten years of November 1, 2027, but the rule does not make utilities pay for the owner's side. Federal infrastructure money passed through the state revolving fund can pay for it, so many utilities offer free or discounted replacement, especially for low-income owners. For fiscal year 2026, EPA allotted $27,456,000 to New Hampshire for lead service line replacement through the Drinking Water State Revolving Fund, and at least $13,453,440 of it must go out as grants or forgivable loans. Compare every state.
What would you pay?
Many utility loans are 0% (enter 0). Private loans run higher. Your real price depends on how far the house sits from the street, digging versus trenchless methods, permits and restoration. This is an estimate, not a quote.
