We use septic tanks for properties where sewerage is not available to dispose of domestic wastewater from toilets, bathrooms, laundries and kitchens.
What types of septic tanks need a permit?
All septic tank installations need approval. The type of approval depends how much sewerage your septic tank disposes per day.
For septic tanks designed to:
dispose less than 5000L > apply for permit with us
dispose of more than 5000L > apply for licence with Environmental Protection Agency (EPA).
When do you need to get the permit?
You must get a permit before any works to install or alter a septic tank system.
