Grey Water Systems in Australia

The reuse of grey water (or greywater) has an enormous potential to reduce drinking water usage in places like Canberra in Australia, but can be difficult to put into practice.

It’s now accepted in most of urban Australia that rainwater can be used for any purpose, including drinking and cooking. In many jurisdictions, you can supply your whole house from rain water.

It’s accepted that blackwater (feces and urine) needs to be sent to a treatment plant. It’s wise to send waste water from the kitchen there, too.

It’s all that other ‘grey water’ that leaves the home with the sewage that offers the tantalising prospect of saving households tens of thousands of litres of drinking-quality water a year, if only we could use it. How much water is that?

According to Sydney Water, “Approximately 61 per cent of the total wastewater produced by an average household can be used as grey water. Kitchen wastewater is not usually included in this amount.”

The table below, reproduced courtesy of Sydney Water, indicates the total amount of wastewater and grey water produced in your home. We have, in fact, removed 44 litres a day coming from the kitchen shown on the Sydney Water table. We believe that kitchen water should not be used as grey water for the garden, because of the fats and solids involved.

Why aren’t there reasonably-priced, simple-to-instal grey water systems? Now there are!

Grey water diverter systems such as the eco-Care don’t require approval for installation in Victoria, NSW, Queensland or the ACT. The Queensland Government has passed legislation permitting grey water systems from March 2006.

Now, let’s have a look at some of the grey water systems available on the market that overcome or go around the problems. They vary in the water sources they use, and where they send it to.
