Greywater reuse
Greywater is waste water generated from bathrooms (showers, baths and hand basins), laundries (washing machines and troughs) and kitchens (sinks and dishwashers).
Permanent greywater systems
If you want to install a permanent greywater system, including diversion devices and/or treatment systems, you will need to lodge an application for a Plumbing Permit through PlanBuild.
PlanBuild
As part of your application, you need to supply supporting documents, which may include site plans, appropriate hydraulic calculations and documentation, and a Geotechnical Assessment Report. These documents are to be completed by a suitably qualified engineer.
