Trade waste approval (for liquid waste discharge to sewer) - Queensland


If your business discharges any liquid trade waste to sewer (other than domestic sewerage) then you require a trade waste approval.

Trade waste is defined as: waterborne waste from business, trade or manufacturing premises, other than waste that is a prohibited substance, human waste or stormwater.

A trade waste approval specifies the conditions under which a customer can discharge trade waste into the sewerage system. The purpose of the approval is to manage the potentially adverse effects of waste, which can cause blockages or corrosion, undermine the sewerage treatment process or be harmful to people or the environment.

Trade waste approval is required for a wide range of business activities. Examples of business activities that require trade waste approval are:

  • food and beverage service
  • manufacturing and industrial processes
  • metal processing, finishing, fabricating or engineering operations
  • hospitals, dental clinics, veterinary clinics and educational, testing or research laboratories
  • mechanical workshops, including panel beaters, spray painters, car washes, service stations, wreckers, plant, vehicle and equipment hire and washing)
  • cleaning services, dry cleaning, carpet cleaning, bottle washing and laundry operations
  • commercial swimming pool operation.

For many of the business activities, the relevant water authority may require appropriate pretreatment before allowing discharge to sewer. The pretreatment device requirements may impact on the suitability of premises for discharging trade waste as part of their business activities.
