Wastewater Treatment Systems (WWTS) and Septic Systems are widely used across Australia for sewage and water treatment processing.
A standard style septic tank is a 1,600L concrete tank. The large concrete lid contains two tiny inspection openings and one larger manhole opening. In contrast, WWTS are more sophisticated tank systems which are often emblazoned with the brand name such as AquaNova, Taylex, Biocycle, etc.

Below we will outline the main differences and advantages of introducing either system. Both systems uses bacteria to break down and “eat” the solids and waste that enter the septic tank or treatment system. When the bacteria are alive and healthy, the solids are slowly broken down.
Septic and Waste Water Treatment System Similarities
- Wastewater is treated through having beneficial bacteria break down and digest the waste.
- Sludge is regularly cleaned out of the system
- Regular service intervals are utilised to keep the systems in a healthy and working order
Septic and Waste Water Treatment System Differences
- Wastewater Treatment Systems require electrical power to operate / increased expense
- Wastewater Treatment Systems likely require more maintenance as the technology is more robust
- Septic systems are limited to Anaerobic Bacteria to digest waste
- Effluent from septic systems may only be used underground whilst effluent from a Wastewater Treatment System may be used above ground
Due to Advanced Wastewater Treatment Systems operating with chemicals, filters, pumps, electronics and trenches, they need to be monitored on a regular basis, with most Advanced Wastewater Treatment Systems requiring 3 monthly servicing and 5-7 yearly pump out (emptying).
