The Greywater system at Buninyong Garden is by New Age Water (unfortunately, this local company has gone out of business).
It is connected to the two showers, and has a timer inside it so that any unused greywater is dumped to the sewer within 24 hours (which is a requirement of the Ballarat City Council).
Special soap that is ok for the environment is used, Green tea from Dominant.
April 2008 Update: The plan now is to make ourselves a reed bed system to filter this grey water, and get clean water into a small pond. Hoping for a frog habitat out of this.
2022 Update
All pumps have now stopped working, and it is a major effort to remove the pumps as they are riveted to the bottom of the sump space.
Investigating a simpler set up, with water diverted to sewer, but can be switched to a sump and pumped to plants in the season of major drought.
