Aerobic Treatment Units

Aerobic Treatment Units (ATUs) are self contained electrical wastewater (sewage) treatment systems for use on properties that cannot be connected to the sewerage main. They are designed to receive and treat all household wastewater from the toilet, bathroom, kitchen and laundry. There are several ATU designs approved for use in single houses in Western Australia.

They can also be scaled up in size and used in multiresidential and non-residential developments. However, such larger systems require individual assessment and approval of their technical design.
