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, greywater reuse systems, composting toilets and biological filter systems.
