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.
