Mark’s House – greywater in a new home – Greyflow PS Self Clean System
Our climate has many dry summer months with virtually no rainfall. We have long hot Summers in Perth. Watering restrictions mean we can only use automatic watering systems two days a week. Not only that but our long term average rainfall is decreasing. If more people take control of their homes water usage we could avoid building another desalinisation plant.
Perth people have embraced solar pv systems on their roof, why, well one reason is we can avoid having to build another coal fired power station. Another reason is we love the thought of embracing natures energy. With water in the home we can capture rainwater for usage inside the home to flush toilets and run washing machines. Greywater is using the homes water a second time to go on our garden plants. We don’t need drinking quality water on our garden beds.
A Greywater diversion system that is connected to your Bathroom and Laundry will send that shower/bath water and washing machine water directly to your gardens every time you shower or wash clothes.
In Perth we have the best available Greywater systems in the World. AWWS, Advanced Waste Water Systems, also known as the Greyflow systems have won many awards. Owned and operated by Sam Milani, he has a factory in Malaga. His systems are now exported to many countries around the world and they are continually being improved as the Industry grows. The warranty and back up service provided by AWWS is unsurpassed. We are very lucky in Perth to have Sam and his products, his knowledge on Greywater is sought after widely.
LOCATION & SYSTEM
A new home in Beaconsfield, near Fremantle, has recently installed a Greyflow PS Self clean system. This is a below ground unit suitable for bathroom and laundry and the most common system used in Perth for new homes.
The Builder’s kit was installed during the build process when the Plumber’s did the drainage works.
After building completion the rest of the system was installed. Pump, Cabinet on the wall with the controller and air blower. A 300 watt pump was used, a medium size suitable for most homes.
Dripline irrigation was then positioned to the garden beds to irrigate the new plants.

On every 20th cycle of the pump a self cleaning operation is activated. Air is blown below the filter and sends dirty particulates to the sewer.
Emitters on the dripline spaced at 30 cm intervals provide an even dispersal of greywater to the plants. Approximately 100 lineal metres of dripline has been set up in a grid pattern, with new plants positioned near the dripline emitters.
Maintenance of this system will be required at a minimum of yearly. Preferably the dripline should be flushed out and the filter cleaned 6 monthly to prolong the systems life.

I love using Grey water in my garden because it allows me to minimise the use of scheme water in our garden watering regime with only small changes to the type of cleaning products we use in our laundry and bathroom. It also allows me peace of mind every time I take a shower knowing the water isn’t just going down the drain but directly into my beloved garden.
Sustainable Garden Design Perth
Having Greywater go to my garden means my plants get watered every day of the year when I’m home. The water savings in summer are huge. Installing a greywater system at my own new build was a must, along with a Rainwater tank. Putting these systems in during the build process is easy compared to retrofitting, and generally cheaper. ‘Water Capture’ sell, install and service Greywater systems in Perth.
WaterCraft service a lot of greywater systems across the metro area and see many gardens thriving on the use of greywater. Frequent watering with traces of soap and nutrients works really well for plants on poor sandy soils. But just as you wouldn’t expect your mains water retic system to run for years without any attention, don’t expect your greywater system to keep running without a service!
