Greywater Systems For Homes
At Garden Master, we specialise in the sales, supply, and installation of Greywater Treatment Systems for homes across NSW, VIC, and ACT.
With over 30 years of experience in greywater treatment systems and wastewater management, we are a trusted provider of high-quality solutions designed to support sustainable water practices.
Greywater systems play a crucial role in reducing reliance on rainfall and alleviating the strain on Australia’s precious water resources. By recycling greywater, homeowners can manage water more efficiently and contribute to a sustainable future. At Garden Master, we are committed to delivering top-notch greywater solutions tailored to your needs.
What is Greywater?
Greywater is any wastewater generated in households, excluding sewage (blackwater). Unlike sewage, greywater contains a lower percentage of organic material and originates from sources such as showers, baths, basins, and washing machines. Despite being less contaminated than blackwater, greywater can include a mix of soluble and insoluble substances, such as soaps, detergents, skin cells, dirt, lint, and microbial content.
Effective treatment of greywater is essential to ensure its safe and sustainable reuse. Proper methods are used to address contaminants, including detergent or surfactant residues, organic matter, microbes, and particulates, ensuring the recycled water meets safety and quality standards.
OUR SYSTEMS
Garden Master Greywater Recycling System

ultraGTS Greywater Membrane Bio-Reactor (MBR)
The ultraGTS Grey Water Treatment System can be connected in Modular form, treating up to 5,000 litres daily. Larger systems are designed specifically for the project, whether it be a School, Golf Course, Hotel or entire Apartment Block we can design an ultraGTS Greywater System to suit your needs. For the home, a compact Membrane Bio-Reactor utilises a combination of biological treatment and advanced membrane filtration followed by Ultra Violet Disinfection. Greywater enters the system via an in-ground collection sump and is then automatically dosed into the system. After advanced treatment, the recycled water is stored in a reuse tank ready for you to use at your pleasure.

Garden Master “Elite” STS
If you’re not connected to a town sewerage system, Garden Master can advise you on the best means of sewage treatment. Garden Master “Elite” Advanced Secondary Treatment System is our primary system and is manufactured at our factory, ensuring our exacting standards are being met. The Elite is a single concrete septic tank with a 7100L capacity, perfect for domestic premises with up to 10 people. The team at Garden Master are experts in manufacturing, supplying and installing top-quality Aerated Wastewater Treatment Systems. Our residential septic systems and commercial wastewater management systems have been approved by the NSW, VIC, and ACT departments of health.
Greywater Membrane Bio-Reactor (MBR) System
A Greywater Membrane Bio-Reactor (MBR) is a system that combines biological treatment, advanced membrane filtration, and ultraviolet (UV) disinfection to treat and purify greywater for reuse.
In this greywater treatment system, greywater is initially treated using biological processes, which involve using microorganisms to break down organic matter and remove contaminants. This biological treatment helps reduce pollutant levels and improve water quality.
After the biological treatment, the water passes through a membrane filtration process. Advanced membrane filters, such as ultrafiltration or microfiltration membranes, separate suspended solids, bacteria, and other fine particles from the water. These membranes have tiny pores that allow only clean water molecules to pass through while retaining the contaminants.
Following the membrane filtration, the purified water undergoes ultraviolet (UV) disinfection. UV light exposes the water to a specific wavelength that kills or inactivates any remaining microorganisms, including bacteria, viruses, and parasites. UV disinfection is a chemical-free process and provides additional protection to ensure the water is safe for reuse.
Combining biological treatment, advanced membrane filtration, and UV disinfection, a Greywater MBR system can efficiently treat and purify greywater, making it suitable for various non-potable reuse applications such as irrigation, toilet flushing, and landscape maintenance.
How Is The Greywater Treated For Re-use?
Our Greywater Systems, the ultraGTS, is a modern state of the art Greywater Treatment System employing the latest in Membrane Technology and UV Disinfection.
The ultraGTS is a compact Membrane Bio-Reactor that utilises biological treatment and advanced membrane filtration followed by Ultra Violet Disinfection.
Greywater enters the system via an in-ground collection sump and is then automatically dosed into the system. After advanced treatment, the recycled water is stored in a reuse tank ready for use at your convenience.
The ultraGTS greywater recycling system offers a highly efficient solution for utilising water that would otherwise go to waste through the sewer system. By employing this system, you can effectively reuse previously discarded water.
The ultraGTS has a WaterMark licence (previously a Plumbing Safety licence) and is listed by NSW Health.

With proper treatment, Greywater can be put to good use, including:
- Water for the laundry
- Toilet flushing
- Watering the lawn
- Washing the car
- Irrigation of plants (treated Greywater can be used to irrigate both food and non-food-producing plants. Greywater is high in nutrients such as phosphorus and nitrogen, which provide an excellent food source for plants)
Our greywater treatment plants are suitable for domestic or commercial applications. Please don’t hesitate to get in touch with any questions!
