Lead pipe replacement cost in Delaware (2026)

What homeowners pay, by utility

What drives the price in Delaware

• Length of the line from the curb stop to the house, and whether the meter is inside.
• Depth and soil. Rocky or clay soil and deep lines add labor.
• 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.

Delaware 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 Delaware 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.
