Aerobic Septic Tank Maintenance: What Homeowners Need to Know
If you have an aerobic septic system, you already know it’s different from traditional systems. What you might not know is that aerobic septic tank maintenance is critical to keeping everything running smoothly – and avoiding costly repairs down the road!
What Is an Aerobic Septic System?
Unlike conventional systems that rely solely on gravity and anaerobic bacteria, aerobic systems use oxygen to break down waste more efficiently.
They include multiple chambers, an aerator, and a spray or drip dispersal system. These systems are popular in areas with poor soil drainage, high water tables or small lots – and they require a bit more attention than standard septic systems.

Why Aerobic System Maintenance Matters
Aerobic systems are more complex, which means they have more parts that need regular checkups. Neglecting routine maintenance can lead to system failure, foul odors, soggy yards, or even health hazards. Regular upkeep ensures:
- Efficient wastewater treatment
- Safe dispersal of effluent
- Longer system lifespan
- Compliance with local health regulations
Top 5 Aerobic Septic Tank Maintenance Tasks
1. Pump the Tank Regularly
Even with aerobic treatment, solids build up over time. Most homeowners should pump their septic system every 2–3 years, but check with your installer or local guidelines.
Not pumping regularly can cause your spray to smell and your pump and aerator to fail prematurely.

2. Clean or Replace Air Filters
Aerators need clean air to function. Clogged filters reduce oxygen levels, treatment efficiency and causes heat to build up.
Excessive heat can cause your aerator for fail prematurely. A non-working aerator will cause your spray to smell.

3. Check and Add Disinfectant
Aerobic systems include a disinfection step. Your system is designed for a specific disinfectant – tablets or liquid bleach.
Only use tablets designed for aerobic septic systems – pool chlorine can damage the system.
Disinfectant won’t prevent your system from smelling but will kill any pathogens in the wastewater.

4. Clean or Replace Air Stones
Aerobic systems need air to function. Over time the air stones get clogged and will need to be cleaned or replaced. They should be inspected annually. Failing to pump your tank regularly will cause premature failure.
Clogged air stones will lead to your spray smelling and heat buildup in your aerator (remember, heat is bad!)

5. Maintain Your Distribution System
Aerobic systems have spray or drip distribution.
For systems that spray treated water, the heads can clog or get knocked out of alignment. Keep them clean and properly adjusted.
If your system has drip distribution, the lines need to be back-flushed and filters cleaned.

Consider a Maintenance Plan
Aerobic systems require routine inspections, so many areas – including some Oklahoma towns – mandate a maintenance contract with a licensed provider. A service plan ensures professionals catch problems early, document compliance, and handle the dirty work for you!
