Approved septic tanks

The Health (Treatment of Sewage and Disposal of Effluent and Liquid Waste) Regulation 1974 requires septic tanks to be approved by the Executive Director, Public Health. 

DOH now requires all manufacturers’ to comply with the Code of Practice for Product Approval of Onsite Wastewater Systems which requires all septic tanks to be certified to AS/NZS 1546.1. This will ensure that the quality standards of all septic tanks manufactured in WA are in line with the Australian Standards.

The following tables detail the specifications of precast concrete septic tanks (Table 1) and non-concrete septic tanks (Table 2) approved for use in Western Australia for the treatment of wastewater.
