What is a grease trap? What type do I have?

A grease trap, sometimes referred to as a grease interceptor, is a plumbing device designed to capture fats, oils, and greases (FOG) before entering the wastewater system. Two primary types of grease traps may be at your establishment.

  • Interior traps are usually located in the kitchen area near the sink or dishwasher and tend to hold smaller amounts of FOG.
  • Exterior traps are located outside your building, underground. Exterior traps are much larger, holding thousands of gallons. Many cities require grease traps to be used in commercial kitchens, as they play a critical role in preventing costly sewer problems.

What to expect from your expert SeQuential Technician



We will open the trap and take a picture of what it looked when they arrive. They'll take another picture once your service is complete, so you can ensure that everything was done properly.



Measurements will be taken contents to determine whether you meet your municipality’s requirements. If you don’t, they’ll make a note for an Account Manager to follow up with you to reassess your frequency.



The trap will get pumped out! Our expert technicians make sure to scrape the sides to remove any accumulated FOG, leaving your trap in tip-top shape!



Once your trap has been completely pumped out, the technician will take a picture and complete a FOG report. You’ll receive a copy of this report shortly after your service. If your city requires a copy of your FOG, we can submit it for you.

Why regular grease trap cleanings are important

As water from your sink passes through the grease trap, FOG accumulate and makes it difficult for water to drain. This causes the trap to fill up. By having your trap regularly cleaned, you prevent it from overflowing and avoid expensive plumbing bills. Regularly cleaning your trap also reduces odors, which can be off-putting to your customers.

Recommended cleaning frequency

Cleaning frequency varies on your trap size and the grease your kitchen uses. Most cities require restaurants to clean their trap frequently to maintain less than a specified level of FOG accumulation. This requirement usually results in cleaning at least once each quarter. When you sign up for SeQuential grease trap service, your Account Manager will determine an ideal cleaning frequency.

Failure to clean & service your trap

Failing to service your restaurant grease trap at the proper interval can cause issues. Not only do you increase your risk of smells and overflows, but your grease inspector may also fine you for allowing fats into the sewer system. Moreover, FOG hardens as it accumulates, making it more difficult to remove and increasing the time it takes to clean the trap.
