Trade waste is wastewater generated by commercial or industrial businesses that contains substances harmful to the sewer network — such as grease, oil, chemicals, food scraps, or heavy metals. In Brisbane, trade waste cannot be discharged directly into the sewer without treatment because it can damage pipes and disrupt wastewater treatment processes. All Brisbane businesses generating trade waste must obtain a Trade Waste Agreement from Queensland Urban Utilities (QUU) and install approved treatment devices such as grease traps.
In Brisbane, any food-related business that discharges wastewater containing oils, fats, or grease must install a grease trap. This includes: cafés, restaurants and takeaway shops, commercial kitchens and catering facilities, bakeries, hotels and clubs with food service, aged care and hospital kitchens, supermarkets with fresh food preparation, and any business with a Queensland Urban Utilities Trade Waste Agreement that specifies a grease trap as a condition. The size required depends on your discharge volume.
Grease trap cleaning frequency in Brisbane is set by Queensland Urban Utilities as a condition of your Trade Waste Agreement. General guidelines: high-volume restaurants or takeaways: every 4–6 weeks. Cafés and smaller food businesses: every 8–12 weeks. Light food preparation: every 3–4 months. QUU can inspect and issue penalties if grease traps are found to be overflowing or not cleaned to schedule.
A Trade Waste Agreement is a legal permit issued by Queensland Urban Utilities (QUU) that allows Brisbane businesses to discharge trade waste into the sewer. To get one: (1) Apply to QUU with your business type and estimated discharge volumes. (2) QUU assesses your discharge and sets conditions — including required treatment devices. (3) Install approved pre-treatment equipment (grease trap, interceptor). (4) Have the installation certified by a licensed Brisbane plumber. (5) QUU issues your agreement.
Grease trap installation costs in Brisbane range from $1,500 to $8,000+ depending on trap size and complexity. A small in-ground polyethylene grease trap for a café costs $1,500–$3,000 installed. A medium concrete grease interceptor for a restaurant costs $3,000–$6,000. Large grease arrestors for high-volume commercial kitchens cost $5,000–$15,000+. Costs include supply, excavation, installation, and compliance certification.
If a grease trap overflows or is not maintained in Brisbane, the consequences include: blocked sewer mains causing sewage backups into your premises, fines from Queensland Urban Utilities for breaching your Trade Waste Agreement, potential suspension of your trade waste permit and forced business closure, damage to the sewer network resulting in cost recovery notices, and reputational damage if a sewer overflow affects neighbouring businesses or the public environment.
No. Grease trap installation in Brisbane must be completed by a licensed plumber and comply with specifications set out in your Queensland Urban Utilities Trade Waste Agreement. Self-installation is not accepted for compliance purposes and will not be certified by QUU. The installation must be inspected, certified, and documented by a licensed Brisbane plumber before your Trade Waste Agreement is active. Attempting DIY installation risks penalty notices and delayed business opening.
Industrial drainage refers to heavy-duty drainage systems designed to manage large volumes of wastewater, chemicals, and solid waste generated by manufacturing, food processing, and logistics operations. Brisbane businesses need industrial drainage when: standard PVC drainage is inadequate for the discharge volume or chemical content, the site generates trade waste requiring pre-treatment before sewer discharge, or compliance with HACCP or Australian food safety standards requires specific drainage gradient and hygienic design.
