Approved Wastewater Systems

​Aerobic Treatment Units (ATU's)
​
​In non-sewered areas, septic tanks systems were once the norm. As more Councils require stringent effluent discharge quality, the installation of a secondary treatment system (STS), formerly called an aerobic treatment unit (ATU) in WA.
​In many parts of Australia an STS/ATU is called an Aerated Wastewater Treatment System (AWTS).

Available for both Residential & Commercial.

​These whole-house systems treat all wastes to a secondary standard and the discharge water can then be used to irrigate gardens.

​Septic Tanks and Leach Drains
​
A septic tank is a watertight chamber, typically made of concrete or plastic, that is used for primary treatment. Wastewater flows from the whole house into the tank/s. Settling and anaerobic (without air) processes reduce solids and organics, but the treatment is only moderate.

The first tank or chamber holds gross solids, while the second tank or chamber allows sedimentation of some suspended solids before it passes into the leach field.

Greywater Reuse Systems

Our Greywater Reuse Systems (GRS) Filter systems are diversion systems, not treatment systems, therefore cannot be used to flush the toilets.

Untreated greywater is only authorised to be used to water the gardens (not root vegetables) via subsurface irrigation method (covered by mulch) or under lawns.
