If you live in a house that’s not connected to the main Sydney Water sewage system you’ll need to install the best system possible to dispose of your wastewater. Council approval is required for all on-site sewage systems such as septic tanks to prevent the spread of disease, contamination and odour.

Greywater is wastewater from your home that can be used for irrigation, toilet flushing and washing machines. Greywater comes from the bath, basin, shower and laundry. It cannot be used for drinking water, watering vegetables or topping up rainwater tanks or swimming pools.
Greywater can be reused through manual bucketing, diversion or treatment. Council approval is required for greywater treatment systems.
