Aerobic Septic System Repair Near You in Lafayette
Your aerobic treatment unit (ATU) is the engine of your wastewater system — when one component fails, the entire system falls out of compliance fast. Bayou Teche Septic specializes in aerobic system repair across Lafayette Parish and surrounding Acadiana communities. We service every major ATU brand including Norweco Singulair, Delta Whitewater, Hoot, Clearstream, Jet, and Aqua-Safe. Whether your alarm is sounding, your spray heads have quit, or your air pump has gone silent, we diagnose the issue and get your system back in compliance the same day in most cases.
Aerobic systems are required across much of South Louisiana because our high water table and clay soils make conventional anaerobic drain fields impractical. That added complexity means more components that can fail — and Louisiana DHH regulations require your system to stay operational and under a current service contract. A neglected aerobic system does not just fail; it puts you at risk for fines, permit violations, and untreated effluent reaching your yard or neighboring properties.
Aerobic Components We Repair
- Air pumps and compressors (Hiblow, Gast, Thomas, FPZ) — diaphragm rebuilds and full replacement
- Aerators and venturi diffusers clogged with biomat or scale
- Spray heads, spray lines, and irrigation field pumps
- Chlorinators and chlorine feed tubes — tablet or liquid systems
- Float switches, effluent pumps, and pump tank controls
- Audible and visual alarm panels, control boards, and timers
- Pretreatment tank baffles, filters, and transfer pumps
- Disinfection chambers and UV units where installed
Warning Signs Your Aerobic System Needs Repair
Aerobic systems signal trouble long before a full failure — if you know what to watch for. Call us the moment you notice any of these symptoms. Catching an issue early is the difference between a $200 part and a $6,000 spray-field rebuild.
- Flashing red alarm light or continuous audible alarm on your control panel
- Sewage odor near the aerobic tank, spray heads, or pretreatment lid
- Air pump running louder than usual or silent when it should be humming
- Spray heads that no longer pop up or cycle on schedule
- Soggy ground or standing effluent under the spray field
- Cloudy, dark, or foul-smelling effluent at the discharge point
- Chlorinator empty more quickly than normal — possible overflow or bypass
- Repeated tripped breakers on the aerator or pump circuits
Our Aerobic Repair Process
We do not guess. Every aerobic service call begins with a full diagnostic — we open the control panel, measure air output at the diffuser, test effluent quality, inspect the spray field, and verify chlorinator function before quoting a single repair. You get a clear written estimate with parts, labor, and any DHH compliance paperwork spelled out line by line. Most repairs are completed in one visit because we stock replacement pumps, diffuser stones, and control parts on every truck.
Emergency Aerobic Service in Lafayette
An aerobic alarm at 9 p.m. on a Sunday is still an emergency — raw effluent hitting your yard is a health hazard and a permit violation. We offer same-day emergency response throughout Lafayette, Broussard, Youngsville, Scott, Carencro, Breaux Bridge, and the rest of Lafayette Parish. When you call, you talk to a real tech who can often walk you through resetting the alarm while we roll a truck. If the fix is something you can do safely yourself, we will tell you. If not, we will be there the same day.
Louisiana Department of Health (DHH) regulations require aerobic systems to be inspected and maintained under an active service contract. If you inherited a home with an aerobic system and have no idea what shape it is in, or your previous service contract expired, we can get you back in compliance quickly. We offer annual and semi-annual service contracts that cover inspections, chlorine refills, air-pump diaphragm replacement, and priority emergency response. Every inspection report we file with the parish is detailed, accurate, and delivered on time.
