Accreditations

Every treatment system in Australia is required to be tested to the Australian Standard AS1546.3/2017 or the previous Australian /New Zealand Standard AS/NZS1546.3:2008 testing criteria for home sewage treatment systems.

Once a treatment system has passed the criteria it is then submitted to each state for approval. Each state has a different approval system and some systems may be approved in one state but not another. Listed below are the links to each Treatment Plant’s State Accreditation.
