Grease and Tempe's FOG rules
Under Tempe City Code Sec. 27-22, every food service establishment in Tempe must have either an indoor grease trap or an outdoor grease interceptor. According to the city's FOG program:
- Grease traps are allowed for kitchens with four or fewer fixtures on the grease line, and must be serviced by a permitted non-hazardous liquid waste hauler monthly, or more often if needed.
- Grease interceptors (500 to 2,500 gallons, installed outside) are required for more than four fixtures or any commercial dishwasher, and must be serviced quarterly, or more often if needed.
- The city inspects establishments and reviews pump-out records.
Tempe also runs the voluntary Tempe Grease Cooperative, where the city brokers pricing and service for grease device maintenance. The city's Environmental Services division runs the FOG program and can answer program questions.
Where jetting fits
Pumping the trap or interceptor is the hauler's job. But grease that has already made it into the lines between the fixtures and the trap, or past the device toward the sewer, builds up on the pipe walls. That is where jetting comes in:
- Floor drains that back up during a rush
- Slow three-compartment sinks or dish lines
- Lines that clog again soon after being snaked
- Odors from grease buildup in the line
A contractor can jet the lines, run a camera to check for damage or sags, and suggest a maintenance schedule that works around service hours.

Commercial Kitchen Drain Jetting FAQ
Does jetting replace grease trap pumping?
No. Tempe requires trap and interceptor service by a permitted hauler on a set schedule. Jetting cleans the drain lines themselves.
How often should restaurant lines be jetted?
It depends on the menu, volume and how well the grease device is maintained. A camera inspection after cleaning helps set a sensible schedule.
Can work be done after hours?
Ask when you call. Many commercial drain contractors schedule around service hours, but availability varies.
Who do I call about Tempe's grease rules?
The City of Tempe's Environmental Services division runs the FOG program, including the voluntary Tempe Grease Cooperative. The city's website has current contact details.
