What maintenance does a Georgia aerobic septic system need?
Georgia requires every aerobic septic unit to come with a three-year service policy covering six inspection visits, one every six months. After that, the owner must buy an extended policy or arrange equivalent maintenance for the life of the system, with emergency service available within 48 hours and yearly visit reports filed with the county.

Plain definitions
Aerobic septic terms, defined
- Aerobic treatment unit (ATU)
- An aerobic treatment unit is a septic tank with an air pump or blower that keeps oxygen-loving bacteria working on the wastewater, producing cleaner effluent than a standard anaerobic tank.↗
- NSF/ANSI Standard 40
- NSF/ANSI Standard 40 is the third-party performance test a residential aerobic unit must pass before Georgia will add the model to its approved list.↗
- Authorized representative
- An authorized representative is the dealer or contractor the manufacturer has trained and approved to install, service and stock parts for its aerobic units in Georgia.↗
- Extended service policy
- An extended service policy is the paid maintenance agreement an owner buys after the three-year initial policy ends, required to be at least as thorough as the original.↗
- Data plate
- A data plate is the permanent label on the control box and on the tank or riser listing the manufacturer, model, serial number and rated daily capacity, which a technician reads at every visit.↗
How the job runs
What a service visit covers
- 1
Read the alarm and the panel
The technician checks that the alarm lights and sounds, since it must signal both high water and aeration failure and has to stay live through a breaker trip or pump failure.
GA DPH Manual for On-Site Sewage Management Systems (March 2026), Section D: Pretreatment
- 2
Inspect the moving parts
Through the ground-level access ports, the aerator, blower, diffusers, pumps and any spray or drip controls are inspected, adjusted and serviced. Georgia's service policy names electrical and mechanical components specifically.
GA DPH Manual for On-Site Sewage Management Systems (March 2026), Section D: Pretreatment
- 3
Look at the effluent and solids
Access ports exist for sampling and for removing collected solids by hand or by pumping. Cloudy, smelly effluent or a deep sludge layer tells the technician the unit needs more than an adjustment.

Put problems in writing
If something cannot be fixed on the spot, the owner gets written notice with an estimated correction date. If the problem could cause a backup or surface discharge, the county health office gets a copy.

File the report
Each visit goes into the annual report the manufacturer or distributor files with DPH and the county by March 15. Keep your own copy with the house records.

The whole story
Why lake houses end up with aerobic units
Around Lake Oconee and Lake Sinclair, aerobic units usually are not a choice; the soil makes the choice. A conventional drain field needs 24 inches of soil between the trench bottom and rock or seasonal groundwater. With aerobic pretreatment to Class I effluent, Georgia allows that separation to drop to 12 inches. On a Piedmont point lot with shallow clay over rock, that one rule is often the difference between a permit and no permit.
Every drip field in Georgia also needs aerobic pretreatment ahead of it, so a lake house with drip tubing on a wooded slope has an aerobic unit somewhere between the house and the field. When either part stops working, both are affected.
The catch on the lakes is how the houses are used. Putnam County alone has 2,498 housing units held for seasonal or occasional use. A unit that sits idle for a month and then takes a full house for a holiday weekend is working hard, and a summer storm that cuts power while everyone is home is the worst case: Georgia's manual says aerobic performance starts dropping after an outage of roughly 48 to 72 hours and suggests considering backup power where outages are common.

Aerobic unit alarming? Call (678) 863-5620
- 1. Alarm light or buzzer at the control boxGeorgia requires the alarm to flag high water or aeration failure. Silencing it does not fix either.
- 2. No hum from the blower or aeratorA quiet unit is an unaerated unit; Georgia's manual says performance starts dropping after about 48 to 72 hours without power.
- 3. Strong sewage odor at the lidsThe unit exists to keep air in the wastewater, so a heavy septic smell is a reason to check the aeration equipment.
- 4. Gray or cloudy effluentEffluent heading to a drip field or spray area should be clear; solids carried over will clog emitters.
- 5. Wet spots over the field or tubingSurfacing effluent is a malfunction the county may need to know about, especially near the lake.
- 6. Tripped breaker for the septic circuitReset once; if it trips again, a pump or blower motor may be failing.

FAQ
Aerobic septic maintenance questions
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Do aerobic septic systems in Georgia require a maintenance contract?
Yes, in effect. The first three years of service are included in the purchase price, with six visits. After that the owner must buy an extended service policy or make sure equivalent maintenance and repair is provided, and the state says maintenance and reporting continue for the life of the system.

How often does an aerobic septic system need service?
Georgia's initial service policy calls for an inspection and service visit every six months for the first three years. The extended policy that follows must be at least as extensive, so twice-yearly visits are the practical standard after that as well.
Source: GA DPH Manual for On-Site Sewage Management Systems (March 2026), Section D: Pretreatment
Why is my aerobic septic alarm going off?
Georgia requires the alarm to signal two things: water above normal operating level, or aeration equipment working outside the manufacturer's limits. Common causes are a failed blower, a stuck pump or float, a tripped breaker, or a surge of water. Cut water use and call for service.
Source: GA DPH Manual for On-Site Sewage Management Systems (March 2026), Section D: Pretreatment
Does an aerobic septic tank still need pumping?
Yes. Georgia's manual requires access ports that allow removal of collected residuals by hand or by pumping, and solids build up in any tank. DPH also says additives are not a substitute for pumping. The technician's sludge readings at service visits tell you when it is due.
What happens to an aerobic system during a power outage?
The blower and pumps stop. Georgia's manual says performance begins to decrease after extended outages, generally over 48 to 72 hours, and recommends considering emergency power where outages are common. Use as little water as possible until power returns.

Can any septic contractor work on my aerobic unit?
Georgia requires anyone installing or working on an advanced treatment system to carry a card showing they completed the manufacturer's certification program, and manufacturers report their certified installers and service providers each year. Ask to see the card for your unit's brand.

Who is responsible if an aerobic system fails?
Georgia's manual puts responsibility for proper operation and timely maintenance on the owner of the house. The manufacturer's warranty covers components for at least two years, and the service provider must document problems it cannot fix on the spot.

Does a lake house aerobic system need anything extra when it sits empty?
Leave the power on so the blower and alarm keep running, and ask your service provider how the specific unit should be handled for long absences. Schedule a visit before a busy season. Greene County lists a $175 residential septic evaluation if you want the county's view of an existing system.
