Wastewater management

Apply for product approval

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

If you are a manufacturer or importer of a wastewater management system (WMS), you can apply to get your product approved.

By getting approval, you are authorised to install that particular system anywhere in the NT, subject to compliance with conditions.

You can also apply to get your product varied or extended.
