Greywater and Alternative Toilets
Grey water reuse systems are used to filter wastewater from bathrooms, laundries and sometimes kitchen sources for use in gardens. The systems are not connected to toilets because of the high bacterial load and associated risk of illness.
There are many products available on the market, however the system that is installed must be on this list of approved grey water systems published by the WA Department of Health. The Department also publishes a list of approved composting or waterless toilets.
The installation of a grey water system or alternative toilet is required to undergo the same application and approval process as any other septic system.
