A working knowledge of your aerobic septic system prevents most emergency calls. Below is the same walkthrough we give every new homeowner — plus manuals, chlorination guidance, and alarm troubleshooting.
Six stages, from the moment wastewater leaves your home to the moment cleaned water returns to your yard.
Solids drop out and separate. Grease and lighter waste rise to a scum layer.
Air is pumped in so aerobic bacteria can digest the organics — the heart of the system.
Treated liquid separates from remaining solids; the solids return to the aeration chamber.
Clean liquid is stored, ready to be dispersed on a timed cycle.
Chlorine reduces bacteria to safe levels before dispersal.
Sprinklers distribute the treated, disinfected water across your permitted spray field.
A conventional septic tank relies on bacteria that thrive without oxygen. An aerobic system runs an air compressor to feed oxygen-loving bacteria — they digest waste more thoroughly, so effluent leaves the tank much cleaner and can be safely sprayed onto a lawn instead of dumped into a drain field.
More treatment power means more moving parts: a compressor, an alarm, chlorine, and a control panel. That's why regular inspection is legally required — and why an informed homeowner saves the most money.
Chlorine kills the last remaining bacteria before treated water leaves your system. Homeowners generally choose between two forms — here's how they compare.
| Attribute | Chlorine Tablets | Liquid Bleach |
|---|---|---|
| Chemistry | Calcium hypochlorite — septic-formulated | Sodium hypochlorite — unscented bleach |
| Feeder type | Dry tablet chlorinator | Liquid drip chlorinator |
| Refill cadence | Check monthly; refill as tablets dissolve | Refill jug on a regular routine |
| Do | Use only septic-rated tablets | Use only unscented, non-thickened bleach |
| Don't | Never use pool-store trichlor tablets — they release toxic gas | Never use scented, splash-less, or gel bleach |
Our maintenance contracts are 100% paperless. You can log in any time to check contract status, sign renewals, and review inspection history through our SAFE program.
If you can identify your system by make, we can usually get you a fresh manual. Call the shop or email support with your address.

Silence the alarm on the control panel, check the list below, and if none apply, call the shop for a free repair estimate.
| Likely cause | What to check | Fix |
|---|---|---|
| Power interruption | Recent storm or breaker trip | Reset the breaker feeding the control panel |
| High water level | Excessive household usage or heavy rain | Reduce usage 24 hours; if it doesn't clear, call us |
| Compressor failure | Quiet aeration tank, no bubbling | Diagnostic visit — rebuild or replace |
| Pump failure | Sprinklers stopped cycling | Diagnostic visit — service or replace |
| Float switch | Alarm won't clear after usage drops | Float replacement — a common quick fix |
