Service & Maintenance

We install, service and replace parts for Secondary treatment systems (STS), formerly called aerobic treatment units (ATUs) in WA, as well as, Greywater Reuse, Rainwater Tank & Irrigation Systems.

Secondary treatment systems (STS), formerly called aerobic treatment units (ATUs) in WA, have service requirements under the Health (Treatment of Sewage and Disposal of Effluent and Liquid Waste) Regulations 1974 and the Code of Practice for the Design, Manufacture, Installation and Operation of Aerobic Treatment Units (ATUs) Serving Single Dwellings, pg 34.

Maintenance work on a Secondary treatment systems (STS) can only be carried out by service persons authorised by the Executive Director of Public Health. Water Installations is approved by the Department of Health to service STS units in WA.

We offer a maintenance service for many ATU and STS units, and we also service Greywater systems and Rainwater Tanks.

We recommend that you maintain your own system weekly by washing out your greywater and rainwater tank filters and keeping an eye on your system. Check your irrigation to ensure that water is coming out of the drippers and there are no leaks or blockages. Six monthly services are recommended for greywater and rainwater systems, although an annual service is the minimum requirement for keeping your system in peak operational condition. 
​
ATU and STS units have their own requirements and need to be serviced typically every 3 months depending on the system.
