As there are two different possible causes you must do the following steps to find the source of the smell.
Aerobic treatment system smell.
An aerobic system should not smell if the wastewater is being treated properly.
Aerobic septic systems inject oxygen into sewage waste stimulating the growth of aerobic bacteria which break down and filter the wastewater and solids.
These systems are commonly found in rural areas where public sewers are not available and may be used for a single.
A properly maintained aerobic treatment system should not smell.
Individual septic tanks have the potential to develop an odor that can be released into the air.
See aerobic atu septic problems.
As mentioned aerobic septic systems differ from conventional systems because the aerobic treatment process requires air to be injected and circulated inside the treatment tank.
Aerobic wastewater treatment systems should not smell septic if they do then something is wrong.
Hence your aerobic septic system is made up of a greater number of parts than a conventional system including electrical components and extra tanks.
If you have an aerobic treatment system and there is a septic odor from the septic tanks themselves or when the sprinklers activate especially a strong septic odor which has also been described as a rotten egg smell this type of odor may indicate.
Verify that aerobic system mechanical electrical components are working properly.
An aerobic treatment system or ats often called incorrectly an aerobic septic system is a small scale sewage treatment system similar to a septic tank system but which uses an aerobic process for digestion rather than just the anaerobic process used in septic systems.
Your tanks need to be pumped or.
Usually an odor is related to a lack of oxygen the aerobic bacteria require oxygen to survive which in turn the aerobic bacteria treats the wastewater.
Aerobic treatment unit septic system parts failure.
Chlorine will not solve septic smells.
Microorganisms exist in the septic tank and digest the organic matter yet in turn they produce large quantities of hydrogen sulfide methane gas carbon dioxide and organic acids.
If you smell any odor from your atu something is wrong.
An aerator pump or control valve failure can cause the atu to emit septic smells and risks system damage or even failure by the discharge of inadequately treated wastewater into the effluent disposal bed.
The odor develops from a ph level that is too acidic.
Plus you cannot even add chlorine to the system to reduce the odor either.
