About Aqua Nova

Required in Australia for properties that do not have access to main sewer lines, Aqua Nova is a mini council treatment plant in your own backyard.


Aqua Nova (AQ) is an aerated treatment system designed to treat all wastewater from toilets, kitchens, laundries & showers. Required in Australia for properties that do not have access to main sewer lines, it’s a mini council treatment plant in your own backyard, providing reusable water. Ideal for both commercial and domestic use, AQ is a two tank system that prevents cross contamination, minimising the need for unnecessary pump outs.  There are several different systems available to meet the needs of different sites and council requirements.  It is an environmentally friendly approach for business and land owners who want to channel recycled safe water back into their property. It is helping Australia and other countries to reduce sewerage entering natural waterways.

 Septic Tank v Aqua Nova

A septic tank is a primary treatment system for waste water that is usually discharged underground to naturally transpire, potentially allowing nutrient-rich water to re-enter soil and pollute waterways.  Septic tanks can also be vulnerable to poor soil conditions and high water tables. The Aqua Nova system is different from standard septic tanks because it uses aeration to treat waste water to a secondary level or better, reducing nutrients in effluent so it can be safely irrigated back into soil through gardens and lawns, reducing damage to the environment and fragile waterways. It’s also an economically beneficial alternative, saving you on water bills. If you have a block of land that is not connected to sewage provided by local council, and you want to manage and recycle the waste that you produce through toilets, showers, kitchen and laundry, the most environmental, efficient and economical way, is through an advanced wastewater management system such as the Aqua-Nova.

How Aqua Nova Works


1. Primary treatment
Wastewater flows into the primary tank that allows for the removal of solids and fats from raw sewerage.

2. Aerobic treatment
Once settled, wastewater flows into an aerobic zone that is aerated using a small air compressor. This zone is fitted with media that allows for the growth of aerobic bacteria that biodegrades the residual organic material – making it an environmentally friendly solution.

3. Clarification
The aerated water then undergoes a final clarification. This allows most of the residual solids to settle, which are then returned back to the primary tank.

4. Disinfection
Where specified by local authorities, the clarified water can be disinfected. This is achieved by allowing the water to flow over the chlorine tablets, providing the necessary chlorine concentration to eliminate any residual bacteria.

5. Irrigation
When sufficient wastewater has been treated, a pump will activate. Safe, recycled water is expelled from the pump to water your garden either by sprinkler or subsurface irrigation.
