Greywater guidelines to help create new water efficient homes

9/07/2013

The Water Corporation has partnered with Josh Byrne to develop guidelines for greywater diversion systems in residential homes.

Greywater is water that comes from the bath, spa, shower, bathroom wash basins, washing machines and laundry troughs. A greywater diversion system harnesses this greywater to be used in the garden.

Water Corporation Manager Water Industry Policy Meredith Blais said installing a greywater system is something customers may consider when building a new home.

“We funded the development of these guidelines because of a lack of technical detail on how to install a greywater system during the building phase,” Ms Blais said.

“So, we partnered with Josh Byrne to develop the greywater diversion system guidelines to make it easier for our customers to recycle greywater in their homes.

“The new guidelines will help the Greywater Industry Group to provide guidance to builders on greywater pre-lay and plumbing.”Josh Byrne installing a greywater diversion system

The greywater diversion system guidelines will be launched on Josh Byrne’s online program, Josh’s House, which follows the construction of two 10 star rated homes in Hilton. The program is designed to showcase how sustainable homes can be built at a comparable cost and timeframes as a conventional home. The Water Corporation is also Gold Partner for Josh’s House.

Josh Byrne wanted to get the plumbing designed for Josh’s House to be greywater ready, however, there was little information for his builder and plumber to work from.  Josh’s experience, along with help from the Water Corporation, formed the basis of the guidelines which can now be used to install greywater systems in all new houses.

“These guidelines capture all the necessary details for plumbing pre-lay, information that until now has not been available to the building industry,” said Stewart Dallas, from Josh Byrne and Associates.

The greywater diversion system guidelines can be found on the Greywater Industry Group’s website gwig.org
