Sewage systems

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 systems

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.

Rainwater tanks

In most cases Council approval is not required for rainwater tanks if they meet the criteria listed under Subdivisions 32 and 33 in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 and the State Environmental Planning Policy (Infrastructure) 2007.
