Septic Repair and Drain Field Repair in Florence, SC

Not every septic problem means a new system. Many failures come down to one broken part: a cracked baffle, a crushed line, a pump that quit, or a distribution box that tipped and sent all the water to one trench. Other times the drain field itself is worn out and needs work. Call (843) 960-3805 and we will connect you with an independent septic repair provider serving Florence and the Pee Dee. Florence SC Septic Pros is a referral service operated by Recover Profits Now. We do not pump tanks, inspect systems or dig drain fields; the independent provider you are connected with quotes and does the work.

Warning signs

• Slow drains or backups even soon after the tank was pumped
• Soggy ground, standing water or sewage smell over the drain field
• Bright green, fast-growing grass in stripes over the lines
• A pump alarm sounding, or a pump tank that keeps filling
• Sinking soil over the tank or lines
• Water flowing back into the tank from the field when it is pumped

Common repairs

Baffles and effluent filters

Baffles keep scum and sludge inside the tank. When one breaks off or rots, solids flow into the drain field and clog it. Replacing a baffle or adding an effluent filter is usually a quick, modest repair that protects the field.

Inlet and outlet pipes

Roots, settling soil and vehicles can crack or crush the pipe between the house and the tank or between the tank and the field. The fix is digging down and replacing the damaged section.

Distribution box

Some systems use a box to split effluent among several trenches. If it settles or tips, one trench gets everything and fails early. Releveling or replacing the box can bring the field back into balance.

Pumps and alarms

Systems that pump effluent uphill or to a distant field depend on a pump, floats and an alarm. Floats stick, pumps wear out and alarms fail. A repair visit tests each part.

Drain field repair or replacement

When the soil around the trenches clogs with a biological mat, or the lines are crushed or flooded, the field stops absorbing water. Options range from repairing a section or adding trenches to replacing the field in a new location. The right answer depends on the soil, the space on the lot and what SCDES will permit.

How a repair visit usually goes

1. Diagnosis. The provider asks about symptoms and history, often pumps the tank to see inside, and may run a camera or probe the field.
2. Written options. A clear quote should explain the problem, the fix and whether a permit is needed.
3. Permit if required. Drain field work and other major repairs generally need an SCDES permit. Ask who applies and how long it usually takes.
4. The repair. Parts are replaced or new trenches are dug and laid, then covered and graded.
5. Final check. The provider runs water through the system and explains care going forward.

Typical repair costs

These are typical national-guide ranges from published cost guides, not quotes. Your price depends on what failed, how deep it is and site conditions.

What moves the price

Digging is the big variable. Shallow, easy-to-reach parts are cheaper to fix than deep ones under a driveway or patio. Drain field work depends on the soil, how much of the field must be replaced, whether there is room for a new field, and what kind of system the site allows. Permit fees, hauling fill or sand, and restoring the lawn add to the total. Ask for a line-by-line quote.

How long it takes

Small repairs such as a baffle, filter or float often take a few hours. Line repairs may take a day. Drain field replacement can take several days of work, plus time beforehand for any SCDES site evaluation and permit, and it may have to wait for the ground to dry out after heavy rain.

Why drain fields fail in Florence County

Two homes a mile apart in the Pee Dee can sit on very different ground. The USDA's official soil descriptions show the range on soils found across this part of the coastal plain:

• Norfolk: well drained farmland soil, with the seasonal water table usually 40 to 72 inches down. It is generally the friendliest to a drain field.
• Goldsboro: moderately well drained, with the water table about 18 to 30 inches down from December to April.
• Lynchburg: South Carolina's state soil. It is somewhat poorly drained, with the water table about 6 to 18 inches down in wet seasons. The state soil booklet notes that a conventional system permit cannot be obtained on it.
• Rains: poorly drained, on flats, depressions and Carolina bays, with water within about a foot of the surface in winter. Its reference site is just northeast of Timmonsville.

Add the flood years (October 2015, Hurricane Matthew in 2016 and Hurricane Florence in 2018) and years of missed pumpings, and it is easy to see why some fields near the Lynches, Black Creek or low "bay" ground give out early. A good provider will work out why a field failed, whether that is wet soil, flooding, solids or a tipped distribution box, before replacing it. A replacement field generally needs a new permit, and the state's Florence office handles Florence and Darlington counties. To check your own lot, the USDA's free Web Soil Survey maps soil series parcel by parcel. See our permits, soils and flooding page for more.

Questions to ask

• What exactly failed, and how do you know?
• Is there a smaller repair that could work before replacing the field?
• Does this repair need an SCDES permit, and who applies for it?
• What is your SCDES installer license, and what tier?
• What does the quote include for digging, fill, hauling and lawn restoration?

South Carolina permits and licenses

In South Carolina, septic systems (the state calls them onsite wastewater systems) are regulated by the South Carolina Department of Environmental Services, or SCDES. SCDES took over the septic program when the old Department of Health and Environmental Control (DHEC) was split into two agencies on July 1, 2024, so older paperwork and websites may still say DHEC. SCDES issues the permits for new systems and licenses the people who do the work: septic system installers, under a tiered license, and septic pumper/haulers who clean tanks and haul the waste. Ask any provider for their SCDES license before work starts, and ask whether your job needs an SCDES permit and who will apply for it.
