Understanding Septic Systems
What is a septic system?
A septic system is an underground wastewater treatment system commonly used in rural areas or homes that are not connected to a municipal sewer system. It is designed to treat and dispose of household wastewater, including sewage and greywater, in a safe and environmentally friendly manner.
How does a septic system work?
A septic system works by relying on natural processes to treat the wastewater. It consists of a septic tank, where the wastewater initially flows, and a drainfield, where the treated water is dispersed into the soil. The bacteria in the septic tank break down the solids in the wastewater, while the drainfield allows for the natural filtration and absorption of the water into the surrounding soil.
Why are septic systems important?
Septic systems are important because they provide an effective solution for managing household wastewater in areas where a municipal sewer system is not available. They help protect the environment by treating wastewater on-site and preventing the contamination of local water sources. Additionally, septic systems help maintain public health by preventing the spread of diseases caused by untreated sewage.
Introduction to Aerobic Septic Systems
What is an aerobic septic system?
An aerobic septic system is a more advanced and efficient alternative to traditional septic systems. Unlike traditional systems that rely solely on anaerobic bacteria, aerobic septic systems use aerobic bacteria, which require oxygen to function. This additional oxygen allows for more efficient decomposition of waste and higher quality treatment of the wastewater.
How does an aerobic septic system differ from a traditional septic system?
The main difference between an aerobic septic system and a traditional septic system lies in the treatment process. In an aerobic system, the aerobic bacteria in the system require oxygen to break down organic matter and convert it into harmless byproducts. This process produces cleaner and clearer water compared to the anaerobic process in traditional systems.
Additionally, aerobic systems often include additional components such as aerators, clarifiers, and disinfection units to enhance the treatment process and improve the quality of the treated water. These components make aerobic septic systems more efficient and effective in treating wastewater.
Components of an Aerobic Septic System
Aerobic septic tank
One of the key components of an aerobic septic system is the aerobic septic tank. This tank is similar to a traditional septic tank but is designed to introduce oxygen into the wastewater. It typically has three chambers: a settling chamber, an aeration chamber, and a final settling chamber. The settling chambers allow solids to separate from the wastewater, while the aeration chamber introduces oxygen to encourage the growth of aerobic bacteria.
Aerator
The aerator is a mechanical device that supplies oxygen to the aerobic septic tank. It typically consists of a pump and diffuser, which inject air into the wastewater. The aerator ensures a constant supply of oxygen to the aerobic bacteria, allowing them to thrive and effectively break down the waste.
Clarifier
The clarifier is responsible for separating the solids from the treated water. It is typically located after the aerobic septic tank and allows any remaining solids to settle to the bottom of the tank. The clarified water is then directed to the disinfection unit for further treatment.
Disinfection unit
The disinfection unit is an optional component in an aerobic septic system. It is used to further treat the clarified water and remove any remaining pathogens or bacteria. Common disinfection methods include ultraviolet (UV) light treatment or chlorination. The treated water is then safe to be released into the environment or reused for irrigation purposes.
Functioning of an Aerobic Septic System
Wastewater treatment process in aerobic systems
In aerobic septic systems, the wastewater treatment process begins in the aerobic septic tank. As the wastewater enters the tank, the first settling chamber allows the solids to settle at the bottom. The liquid then flows into the aeration chamber, where the aerobic bacteria thrive in the presence of oxygen. These bacteria break down organic matter through the process of aerobic digestion. The final settling chamber allows any remaining solids to settle before the water moves to the next stage of treatment.
Role of the aerobic septic tank
The aerobic septic tank is a crucial component in an aerobic septic system. It provides the necessary environment for aerobic bacteria to flourish, promoting the efficient decomposition of organic matter. The tank’s design allows for the separation of solids and the retention of wastewater for sufficient contact time with the bacteria.

The aerator plays a vital role in an aerobic septic system by supplying oxygen to the septic tank. The pump in the aerator draws air and injects it into the wastewater through the diffuser. This continuous supply of oxygen creates the perfect conditions for the aerobic bacteria to multiply and decompose the waste more efficiently compared to traditional septic systems.
Importance of the clarifier
The clarifier is an important component in an aerobic septic system as it ensures the separation of solids from the treated water. It allows any remaining solids to settle to the bottom of the tank, reducing the amount of suspended solids in the effluent. This process helps prevent clogging of the drainfield and ensures the overall effectiveness of the system.
Disinfection unit and its purpose
The disinfection unit, if installed, further enhances the treatment process in an aerobic septic system. It eliminates any remaining pathogens or bacteria in the treated water, making it safe for release into the environment or reuse for irrigation purposes. Ultraviolet (UV) light treatment or chlorination are commonly used methods to disinfect the water, ensuring it meets the necessary quality standards.
