GWIG – Greywater & Wastewater Industry Group

GWIG is a non-profit organisation which was formed in late 2010 in order to provide a united voice for a WA industry that is largely unsupported and under-acknowledged for the important work that it does.

We have developed a number of aims to enhance community awareness and increase the uptake of wastewater re-use in all its forms.

GWIG is working towards a responsible, sustainable use of water in Western Australia and promoting the re-use of wastewater through education, public promotions and professional development, for residential, large-scale industrial and commercial premises.

I have been lucky enough to have had a greywater system in our Hami Hill Sustainable Home since 2011. As a family of five we have worked the system pretty hard and I have been amazed at the reliability and efficiency of the system as well as just how readily my landscape has adapted and even thrived through the use of greywater. Plants that I had originally thought might struggle with greywater – Grevilleas, citrus, fruit trees and Hakeas – have all responded really well and our soil continues to build and improve under this greywater regime.

When I think that this system has saved me hundreds of thousands of litres of scheme water, not too mention fertiliser and that is essentially a hassle free system, I couldn’t imagine a scenario where greywater was not front and centre in my water efficiency regime.
