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.
Certificates issued against AS/NZS 1546.3:2008 will continue to be valid for 2 years from commencement of the Environment Protection Act 2017 (that is, to 30 June 2023), or earlier if the expiry date in the certificate is earlier.
Find out about the regulatory framework and approval process for onsite wastewater treatment systems.
