How to Choose a Septic Tank Company
Verify licences and registrations
All septic tank installation and repair work must be performed by a licensed plumber in Australia. Liquid waste pump-out contractors must hold a liquid waste transport licence. For AWTS installations, confirm the installer is familiar with your council's specific approval requirements.
Get a site assessment first
Never accept a firm price for a new installation or major repair without a site assessment. Soil conditions, water table depth, access, and setback requirements vary enormously and directly affect system choice and cost. A reputable company will visit before quoting.
Understand ongoing maintenance costs
AWTS systems require quarterly or 4-monthly inspections under most council requirements — this is an ongoing annual cost of $200–$600. Budget for this when comparing AWTS versus conventional system costs, as the ongoing maintenance obligation runs for the life of the system.
Check council approval status
Confirm the company handles the council approval process as part of the installation contract. Approvals in some councils can take 4–8 weeks and require specific documentation. Delays in obtaining approval before installation add cost and scheduling risk.
Ask about the product warranty
Concrete and polyethylene tanks typically carry 25–50 year structural warranties. AWTS mechanical components (pumps, aerators, control panels) typically carry 1–3 year warranties. Understand what is covered and by whom before purchasing.
Confirm service area and parts availability
If you are in a rural or remote area, confirm the installer has a service network that can attend within 48–72 hours for breakdowns. Parts availability for AWTS units is critical — avoid obscure imported brands where replacement parts may have long lead times.
