Everything You Need To Know About AWTS Systems
If you’re researching an AWTS (Aerated Wastewater Treatment System), it’s important to understand how these systems work, where they’re used, and the wastewater treatment options available for your property.
Aerated Wastewater Treatment Systems are commonly installed on properties that are not connected to a town sewer network. They use a combination of aeration, biological treatment and disinfection processes to treat household wastewater before it is safely dispersed via a suitable irrigation system.
While the term AWTS is widely recognised throughout Australia, wastewater treatment technology has evolved significantly in recent years. Today, many property owners are choosing modern Advanced Secondary Treatment Systems (STS) that deliver high-quality wastewater treatment outcomes while meeting the requirements of local councils and regulatory authorities.
At Garden Master, we have more than 30 years of experience providing environmentally responsible wastewater treatment solutions across NSW, ACT and Victoria. Our team can assess your property, explain your options, and recommend the most suitable system for your site’s specific conditions and wastewater requirements.

What Is An AWTS?
AWTS stands for Aerated Wastewater Treatment System. These systems are designed to treat wastewater generated from homes and commercial properties where access to a centralised sewer system is unavailable.
Unlike a conventional septic tank, which primarily separates solids from wastewater, an AWTS uses aeration and biological treatment processes to further break down organic matter and improve the quality of the treated water.
Wastewater from bathrooms, laundries, kitchens and toilets enters the treatment system, where naturally occurring bacteria help break down contaminants. Air is introduced into the treatment process to promote the growth of beneficial microorganisms, thereby significantly improving treatment performance compared to traditional septic systems.
Once treated, the wastewater undergoes additional clarification and disinfection before being distributed to an approved irrigation area.
AWTS systems have become a popular solution for properties located in rural, regional and semi-rural areas where connection to a municipal sewer network is not possible. They provide an effective method for managing wastewater on-site while helping protect surrounding land and waterways.
Although many people use the term AWTS when researching wastewater treatment systems, it is important to understand that modern treatment technologies now extend beyond traditional AWTS designs. Advanced Secondary Treatment Systems offer an alternative approach that can provide excellent wastewater treatment performance while meeting the needs of a wide range of residential and commercial properties.
How Does An Aerated Wastewater Treatment System Work?
An Aerated Wastewater Treatment System (AWTS) treats household and commercial wastewater through a series of treatment stages designed to reduce contaminants and improve water quality before it is safely dispersed via an approved irrigation area.
Unlike a conventional septic tank, which relies primarily on the settling of solids, an AWTS introduces oxygen into the treatment process. This encourages the growth of beneficial bacteria that help break down organic matter and produce a higher-quality treated effluent.
While individual system designs may vary, most AWTS units operate using the following treatment stages:
Wastewater from toilets, bathrooms, laundries and kitchens enters the primary treatment chamber. In this chamber, heavier solids settle to the bottom while oils and grease float to the surface. This process separates solid waste from the liquid wastewater and begins the treatment cycle.
The partially treated wastewater then flows into the aeration chamber. Air is continuously introduced into the wastewater to support naturally occurring aerobic bacteria.
These microorganisms break down dissolved organic matter and significantly reduce contaminants within the wastewater. This stage is one of the key differences between an AWTS and a traditional septic tank.
Following aeration, the wastewater enters a clarification chamber, where suspended particles and biological solids settle out of the treated water.
The clarified water then proceeds to the next stage of treatment, while settled solids are retained in the system for further processing.
Before leaving the treatment system, the wastewater is disinfected to further reduce harmful bacteria and pathogens.
Depending on the system design, this may be achieved through chlorination, ultraviolet treatment or other approved disinfection methods.
The final treated effluent is distributed through an approved subsurface irrigation area. This allows the water to be safely absorbed into the soil while supporting sustainable wastewater management on properties that are not connected to a municipal sewer network.
Why Is Proper System Selection Important?
Not all wastewater treatment systems operate in the same way, and the most suitable solution will depend on factors such as site conditions, soil characteristics, occupancy levels, local council requirements and environmental considerations.
For this reason, it is important to understand the differences between traditional AWTS systems and newer treatment technologies when selecting a wastewater solution for your property.
Are AWTS And Advanced Secondary Treatment Systems The Same?
Many people researching onsite wastewater treatment use the terms AWTS (Aerated Wastewater Treatment System) and Advanced Secondary Treatment System (STS) interchangeably. While both systems are designed to treat household wastewater to a standard suitable for land application, there are important differences in how they achieve this outcome.
Traditional AWTS systems rely on a combination of aeration, biological treatment, clarification and disinfection to treat wastewater. They have been widely used throughout Australia for many years and continue to provide an effective solution for many residential and commercial properties.
However, wastewater treatment technology has continued to evolve. Modern Advanced Secondary Treatment Systems utilise sophisticated processes to achieve high-quality wastewater treatment while meeting strict environmental and regulatory requirements.
An Advanced Secondary Treatment System is engineered to treat wastewater beyond the capabilities of a conventional septic tank and may utilise enhanced treatment processes to improve effluent quality before it is used for irrigation or disposal. These systems are commonly selected for properties where environmental sensitivity, site constraints or local authority requirements demand a higher level of wastewater treatment performance.
For many property owners, the term “AWTS” has become a general description for any wastewater treatment system that provides advanced treatment. In reality, there are several different wastewater treatment technologies available, each designed to suit specific site conditions, household occupancy levels and environmental considerations.
This is why selecting the right system should never be based solely on a product name or acronym. Factors such as soil conditions, available land area, council requirements, wastewater volumes and long-term maintenance requirements all play an important role in determining the most suitable solution.
At Garden Master, we work closely with homeowners, builders, developers and consultants to assess individual site requirements and recommend the most appropriate wastewater treatment system. In many cases, an Advanced Secondary Treatment System may offer significant advantages over traditional wastewater treatment approaches, depending on the property’s unique characteristics and treatment objectives.
The key is understanding the differences between available technologies and selecting a system that provides reliable, long-term performance while meeting both environmental and regulatory requirements.
Why More Property Owners Are Choosing Advanced Secondary Treatment Systems
As wastewater treatment technology continues to evolve, many homeowners, builders, and developers are looking beyond traditional treatment methods and exploring modern solutions that deliver reliable, long-term performance while meeting increasingly stringent environmental standards.
Advanced Secondary Treatment Systems have become a popular choice for a wide range of residential and commercial applications because they are designed to produce high-quality treated effluent suitable for approved land-application systems.
For properties with challenging site conditions, limited usable land, environmental sensitivities, or specific council requirements, selecting the right wastewater treatment technology can significantly impact system performance, maintenance requirements, and long-term outcomes.
