Aerobic treatment units are common across the Midlands — from the clay-heavy lots east of Columbia to the tighter soils and lakeside properties around Lake Murray where a conventional drain field simply can't handle the flow. If your home runs an aerobic (ATU) system that sprays treated effluent across the yard instead of draining into a gravel field, it needs regular, knowledgeable service to keep working and to stay within SCDHEC rules.
Aerobic isn't the same as conventional — and it needs more attention
A conventional septic system is mostly passive. An aerobic system actively pumps air into the tank to grow the bacteria that break waste down to a cleaner standard, then disinfects and sprays it. Those moving parts — the aerator, the chlorinator, the pump, the spray heads, the alarm — are exactly what fails, and in South Carolina's humid climate and clay soils they fail on a schedule. Regular service is what keeps a small part from becoming a yard full of untreated effluent.
What we do on a service visit
- Aerator / air pump — test air output, clean or rebuild it, and replace it before it quits and the tank turns septic.
- Disinfection — check and refill chlorine so what's sprayed on your yard is actually treated.
- Spray heads and distribution — clean the heads that Midlands grit and iron love to clog, so the field waters evenly instead of pooling.
- Alarm, floats, and filters — verify the high-water alarm and controls so the system warns you early.
- Effluent quality check — confirm clear, odorless output the way SCDHEC expects.
Signs your Columbia ATU needs service now
An alarm at the control panel, sewage odor near the spray field, unusually green or soggy patches in the yard, or slow and gurgling drains inside. Don't wait for the next visit if you see these — call and we'll get out to it.
Local knowledge that matters
We work the specific soils and system brands common around Richland and Lexington counties, keep the fast-moving parts stocked, and handle the SCDHEC-side paperwork so your system stays permitted and documented. If another company installed or neglected your unit, we can take it over and bring it back into good standing.
Frequently asked questions
Do aerobic systems in SC require ongoing maintenance?
Yes — SCDHEC expects these systems to be maintained and functioning; the moving parts genuinely need it regardless.
The alarm is going off — now what?
Ease up on water use and call us. It usually means a float tripped or the aerator faulted; we'll diagnose and fix it.
Can you service a system another company installed?
Absolutely — we service and take over maintenance on existing aerobic units across the Midlands. Keep your aerobic system healthy, compliant, and out of your yard. Reach out for a maintenance plan or to get a neglected system back on track.
What it costs, and taking over a neglected system
An aerobic system has a modest but real annual cost — the routine inspections, chlorine, and the odd part — and it is far cheaper than the cleanup when one is ignored. If a previous owner or a hands-off company let yours slide, we can assess it, bring it back into working order, and put it on a regular schedule so it stops being a worry. We quote repairs before doing them, so there are no surprises on the bill.
Do you install aerobic systems too? Yes. When a unit is past economical repair or you are building, we size and install an aerobic system suited to Midlands soils and then maintain it, so it is documented and functioning from the start.
How do I know if I even have an aerobic system? If you have a control panel with an alarm, an air pump running near the tank, and sprinkler-style heads that run in the yard, it is almost certainly aerobic. We can confirm on a visit.
