Domestic Below-Ground ATU System

Coerco’s Aquarius® Below-Ground ATU Systems for residential applications are ideal for treating wastewater from toilets, kitchens, showers, and many more. Approved by the Department of Health of WA, the treated wastewater can be reused for irrigation and landscaping, enhancing water usage efficiency.  

Efficient Domestic Below-Ground Aerobic Treatment Unit Systems


Coerco’s Aquarius® Below-Ground ATU Systems are designed to treat all wastewater in your home from the kitchen, bathroom, shower, and laundry, as per Department of Health of WA Standards. This recycled water can be used for irrigation landscaping or lawns, or disposed of into flatbed or conventional leach drains and soak wells. 

The O-2 NR and O-3 models feature nutrient-retention capabilities, further treating the water to reduce phosphorous and nitrogen, which is crucial if the discharged effluent is recycled in water catchment or environmental areas.   

O-3 models, on the other hand, use Ozone as a final disinfectant, producing oxygen as a by-product, making it the most environmentally friendly ATU option.
