Domestic Waste Water Cycle
Human use of water affects the natural water cycle in many ways.
When we use water for domestic, agricultural, or industrial purposes, it is drawn from its natural course and must be returned to the environment.
Wastewater from homes falls into two main categories. Greywater comes from everyday sources such as drains, sinks, baths, and showers. It makes up the largest portion of household wastewater. Blackwater, on the other hand, is generated from toilets and contains higher levels of waste.
All domestic wastewater must be collected and treated in accordance with statutory requirements before being returned to the water cycle.
Homes that are not connected to a central sewage system must install a fully approved on-site wastewater treatment system.
Garden Master Septic Systems treats both blackwater and greywater. After treatment, the clean, recycled water is safely returned to the environment through a suitable irrigation system and applied to the designated land area.


Our Range of Quality Wastewater Treatment Systems
Garden Master ‘Elite’ Advanced Secondary Treatment System (STS)
The Garden Master “Elite” Advanced Secondary Treatment System (STS) is our leading septic solution for residential properties.This single concrete tank has a 7100-litre capacity, making it ideal for homes with up to 10 people. It provides reliable wastewater treatment in a compact design, ensuring efficient operation and compliance with local environmental standards.
Small Commercial Wastewater Treatment System
The Garden Master Small Commercial Wastewater Treatment System features two concrete septic tanks for effective wastewater processing. It is designed for commercial premises with up to 20 people and provides reliable, environmentally responsible performance. For best results, we recommend using sub-surface irrigation, which allows the treated water to be safely absorbed into the soil. This system is an eco-friendly solution ideal for small businesses, community facilities, and rural sites.Poly & Concrete Septic Tanks
Garden Master offers a range of durable poly and concrete septic tanks, available in various sizes to suit your property and wastewater requirements. Each tank is built to deliver long-lasting performance, ensuring reliable operation and compliance with Australian standards.Subsurface Irrigation
Subsurface irrigation is the preferred method for disposing of cleaned and disinfected wastewater, as recommended by most local authorities.Its main advantage is safety — the treated water remains underground, so there is no contact with people, pets, or livestock. This method also helps protect the environment by allowing the water to re-enter the soil naturally, supporting healthy plant growth.
Large Commercial Sewage Treatment System
Our Large Commercial Sewage Treatment Systems are custom-designed to suit your site’s specific requirements. They are ideal for premises that serve more than 20 people and are built for long-term reliability and compliance. We provide bespoke wastewater solutions for a wide range of commercial and industrial clients, including vineyards, mine sites, horse studs, hospitality venues, tourism operators, cabins, and accommodation providers. Each system is designed to deliver efficient performance while meeting environmental and regulatory standards.Pump Stations
We supply and install modern pump stations designed to suit your specific site requirements. Each system includes high-quality pumps and equipment that efficiently move fluids from one location to another. Our water pumping stations range in size from 500 litres to 3000 litres and come fitted with reliable pumps chosen for each application.Greywater Recycling Systems
With over 30 years of experience in greywater and wastewater treatment, Garden Master delivers systems you can trust. Our ultraGTS greywater treatment system is a compact Membrane Bio-Reactor (MBR) that combines biological treatment with advanced membrane filtration. After filtration, the water undergoes ultraviolet (UV) disinfection, ensuring it is clean and safe to return to the environment.Septic Tanks & Wastewater Systems

Testimonials
What our customers say...
We recently had a Septic Tank and System installed on our property.
We had no experience in this, having never had to have one before as this is our first ‘Rural’ property.
We decided to go with ‘Garden Master’ because we found that they we a Family owned, operated and run business, their pricing was more than competitive and Troy Speed was very knowledgeable, helpful, patient and we feel cared enough to go above and beyond what was necessary.
The team kept us informed and guided us throughout the entire (to us complicated) process making it stress free for us and giving us full confidence in our (as it turned out) correct decision, even to point handling all of the Council requirements.
Therefore we completely recommend Garden Master to anyone that needs a Septic Tank and system as we are more than happy with our choice and we look forward to dealing with them for any of our service needs in the future as we have every confidence in their ongoing support.
18months in…. with my new Garden Master system. Happy to share my testimonial. Replacing a competitor brand system after 25 years. Fitted now with new Garden Master Septic system. Did have a wiring issue,but on house side,and not on the Garden Master side. 10/10 score for help,and assistance , to rectify this from their team of technicians. Here is a good tip.
When the electrican needs to connect to the system, make sure the sparky, has plenty of wire( good loop),on the tails when connecting, to the connection box.
If the wiring moves under the weight of dirt , or active clay,it could pull the tails from the connector box, and you”ll lose power. Highly recommend the Garden Master system.
I can not recommend Garden Master any more highly! Their management of our existing system is fantastic and Troy has gone above and beyond with respect to our application for additional system for our new build! He is knowledgeable across all local council’s individual requirements, and will ensure his application is exactly what they are seeking. If you need a new septic system definitely go and see Garden Master!
Highly recommend Garden Master at Rutherford. Troy and his team are extremely helpful and communication and customer service is top on their priority. A lot of other companies say they will call you back, or they are going to do something and they never do. However, Troy was on the ball and always called back and actioned what he said he would do. Even going over and above to help us through some council issues. Pricing was the best around and we have recommended to many others building in the estate we are building in, to go and see Troy and his team. They will not be disappointed!!
If anyone is in the market for a new Aerated waste water system i wouldn’t go anywhere else but Garden master.
Not only is the product itself fabulous but you can see that the time and effort has gone into the system making sure it works great.
the service techs seem to know what they are doing and gave me a run through of the system and if i ever have any questions which i definitely do regarding the products that go into the system the office staff are incredibly helpful and so easy to talk to unlike other office environments that try to get you off the phone quickly.i will continue to get my system serviced by these guys, they do a great job!
