Manufacturers of on-site wastewater treatment systems informed EPA that their systems were certified under an Australian Standard and EPA listed them in the following tables to support residents and council officers.

Duty holders must get a copy of the current ‘certificate of conformity’ from the manufacturer and attach it to their permit application to council. Council assessors who receive on-site wastewater system applications should ensure the certificate is valid.

On-site systems certified under AS/NZS 1546.3: 2008 – On-site domestic wastewater treatment units, Part 3: Aerated wastewater treatment systems are also in the list and could be used until the certificate expires.

Find out about the regulatory framework and approval process for onsite wastewater treatment systems.
