State Accreditations

Every treatment system in Australia is required to be tested for a six month period under the 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.

Please note that each state has a different approval system and that some systems may be approved in one state but not another.

Listed below are the links to each Treatment Plant's State Accreditation.
