Safe and compliant greywater reuse requires access to greywater drainage without contamination from toilet and kitchen wastewater. Unfortunately current industry standard plumbing methods makes this very difficult and costly to retrofit, if not impossible in most situations once a house has been built.

With a bit of thought, plumbing drainage can easily be configured to be ‘greywater ready’ for the installation of an approved greywater system at a later date. This simply means that the drainage pipes are laid out so that the suitable greywater streams (bath/shower, washing machine, laundry trough and hand basins) can be directed via a greywater system prior to joining the main sewer line.
