Septic & Drain Field Repair Cost in Lumberton, NC

Drain field and repair prices (national)

Every figure here is a national range or average, not a North Carolina or Robeson County quote. HomeServe's drain field and leach field ranges cite HomeGuide.

Whole systems and tanks (national)

The system type isn't a menu choice. The soil evaluation and the permitted design decide what a lot can use, and a wetter site can push the design toward a pump or treatment unit. Alternative septic systems explains North Carolina's system types.

Inspections and pumping (national)

• Maintenance inspection: $150 to $450; comprehensive inspection: about $300 to $650; average $290, citing HomeGuide (HomeServe, July 2024).
• Camera inspection of the lines: $125 to $500 (HomeServe, July 2024).
• Pump-out: average $420, typical $290 to $560 (This Old House, May 2026). By tank size, from Angi data in the same guide: 1,000 gallons $225 to $400; 1,250 gallons $275 to $500.

The local fees that are official

The schedule shows no effective date, so confirm any amount with the health department's on-site line, (910) 272-6560. It also lists a filing fee for the private engineer and AOWE routes; state law caps the health department's fee on those routes at $35, so ask what the county charges now.

How Robeson's fees compare

This is where the county stands out. HomeServe's November 2025 guide puts a septic permit at $250 to $1,000 nationally and a soil survey at $100 to $400; its June 2025 guide puts a perc test at $600 to $2,000. In Robeson County, the health department does site and soil evaluations itself, and North Carolina doesn't require a private soil evaluator for a repair. So a repair's county-side cost can start at the $100 repair evaluation, and a new system's at the $600 new soil evaluation, before any contractor's price.

The line items inside a bill

• Labor. HomeServe's June 2025 guide says labor often accounts for at least 60 percent of a leach field job.
• Pumping. A complete sale inspection under the state's inspector standards calls for pumping the tank, and a repair may need it emptied too. Ask whether it's in the quote.
• Parts. A distribution box, baffle, filter, pump or lid, priced in the table above.
• New trenches. Line at $40 to $180 per linear foot (HomeServe, September 2024), plus gravel or other media, depending on the design.
• Design work, if you choose a private engineer or AOWE instead of the county's evaluation.
• County fees, from the schedule above.

What moves the price

• What actually failed. A part is a small dig; a field is a rebuild.
• The soil and the water table. On one Fairmont-area tract, a federal soil report shows the water table about 0 to 12 inches down in one soil and 40 to 72 inches in another. Wetter ground can mean a pumped or treated system instead of gravity trenches, and national guides put mounds and aerobic units at roughly $10,000 to $20,000.
• Room on the lot. The new field has to stay at least 50 feet from a private household well and away from other setbacks in Rule .0601.
• Ongoing costs. Types IV, V and VI need a certified operator under contract, plus county compliance inspections on a schedule set by type.

Ways the bill can come down

Ask whether the problem is a part or the field before anyone prices a rebuild. If the house is in one of the towns with a sewer plant, ask the town whether connecting is an option. Use the county's own soil evaluation unless you have a reason to go private. And if you're adding a bedroom rather than replacing a system, ask whether an existing system evaluation, posted at $200, answers the question. We didn't find a Robeson County or statewide septic repair assistance program we could confirm; ask the health department, 910-671-3200, what may be available.

Who this page isn't for

If you need to know whether you have a problem at all, start with septic backing up or drain field repair. If a flood just went through, cost comes later: see septic after a flood.

Cost questions

Is the $100 repair evaluation the whole county cost of a repair?

It's the posted evaluation fee. Other lines can apply, such as $100 if the site is unprepared at the visit or a permit amendment. Ask the on-site line what to expect for your job.

Why do the published ranges disagree so much?

Each guide uses its own data, categories and dates, from late 2023 to 2026. Some cite other sources: HomeServe's drain field ranges come from HomeGuide, and Bob Vila's tank-and-field average comes from Angi.

What does a pump-out cost in Lumberton?

We found no local price list. This Old House's May 2026 guide gives a national average of $420, and each pump-out company sets its own rate.

Should I get the price in writing?

Yes. The contractor sets the price, and a written quote that lists the work, any county fees, materials, how the yard will be left and the warranty is the figure to rely on.
