Approved products

All on-site wastewater systems with a design flow of up to 2,000 litres per day must be product approved by the Department of Health before they can be sold and installed in the Northern Territory (NT).

Product approval provides authorisation for that type of system to be installed anywhere in the NT, subject to compliance with conditions.

This includes septic tanks, aerated wastewater treatment systems, alternative wastewater systems, greywater systems, composting toilets and effluent disposal systems.

Secondary treatment systems

Secondary Treatment Systems (STS) include all aerated wastewater systems, reed beds and aerated sand filters.

If you are a manufacturer of an existing or new STS up to 2000 litres per day, you need to test and accredit your system against the Australian Standard in order to sell them in the NT.

The new Australian Standard for onsite domestic wastewater treatment units is Part 3: Secondary Treatment Systems AS 1546.3:2017.

You must test and accredit your systems using a Joint Accreditation System of Australia and New Zealand (JAS-NZ) accredited Product Certification Body (PCB).

A PCB certifies that an STS meets the requirements of the AS1546.3 so that it can be assessed for DoH product approval.

You must get accreditation for existing or new systems by 31 December 2020.
