What Is an Aerobic Septic System?

5 min readUpdated June 1, 2026

An aerobic septic system uses oxygen and mechanical aeration to treat wastewater more thoroughly than a conventional tank, then sprays the treated effluent over a lawn, a design that’s very common in Oklahoma because of poor-draining soils.

How it’s different from a conventional system

A conventional septic system relies on anaerobic (no-oxygen) bacteria and lets liquid soak away through a buried drain field. An aerobic system adds an aerator to introduce oxygen, treats the water to a cleaner standard, and then sprays it above ground rather than relying solely on soil absorption.

The parts of an aerobic system

  • Trash/pre-treatment tank to settle solids.
  • Aeration chamber where an aerator adds oxygen.
  • Pump tank and spray heads that disperse treated effluent.
  • Control panel and alarm that warn you of problems.

Do you have one?

If you have sprinkler-style heads fed by your septic, a control panel with an alarm, or a required maintenance contract, you almost certainly have an aerobic system, and Oklahoma requires regular professional maintenance to keep it running and compliant. See our aerobic system service.

Frequently asked questions

What is an aerobic septic system?
A system that adds oxygen via an aerator so bacteria treat waste more thoroughly, then sprays the treated effluent over a lawn. It’s common in Oklahoma where soils drain poorly.
How is aerobic different from conventional septic?
Conventional systems use anaerobic bacteria and a buried drain field. Aerobic systems add oxygen for cleaner treatment and disperse water above ground through spray heads.
Do aerobic systems need more maintenance?
Yes. They have mechanical parts (aerator, pumps, panel) and discharge treated water to the surface, so Oklahoma requires regular professional maintenance.
