Trade waste grease arrestors and grease reduction devices approved by Power and Water Corporation in the Northern Territory as of June 2025.
Before purchasing or installation commences, please contact Power and Water’s Trade Waste Department to ensure that a Trade Waste Application Form has been completed and plumbing plans for installation have been stamped ‘approved’ by Power and Water. Once an application has been received, Power and Water will contact you to discuss the correct and most suitable pre-treatment equipment for your business.
Any businesses unable to install an in-ground grease trap must provide a report by a hydraulic consultant confirming that a minimum 1000 litre grease trap cannot be installed. Power and Water must approve, in writing, the installation of a grease reduction device before installation is carried out. Only products listed in the table below are permitted in the Northern Territory.
Any pump systems related to above ground grease traps will require written pre-approval by Power and Water and Environmental Health before installation.
Installation of a grease trap or grease reduction device can only be carried out by a Northern Territory licensed plumber in accordance with Australian Standard 3500. The location of these devices must ensure they are always readily accessible and sample points supplied on the outlet to sewer in all cases. It is the applicant’s responsibility to contact Plumbing Building Advisory Services on 8999 8985 where required.
Please note: Pre-treatment equipment installed in the Northern Territory that does not meet these standards and guidelines, may require removal at the cost of the installer.
