About Grease Interceptors

Cutaway diagram of a grease interceptorA grease interceptor is much larger than a grease trap and is usually located outside. The minimum size is 1,000 gallons.
 

It too should be cleaned regularly (at least every six months) by a licensed grease hauler or recycler. The actual schedule should be based on your establishment's needs and can range from weekly to every six months.
 

Cleaning the interceptor vaults requires special training and equipment. It is very important that a restaurant representative be present during any cleaning, pumping, or skimming performed by a contractor to ensure that no shortcuts are taken. They should always follow the cleaning requirements outlined in Part 29: Section 29.3.6 PDF document.

Servicing Grease Interceptors

The minimum services should include:
 

  • Complete pumping and cleaning of the interceptor and sample box (not just skimming the grease layer).
     
  • Deodorizing and thorough cleaning of affected areas, as necessary.
     
  • Reclaiming FOG or disposing of it at an approved location.
     
  • Refilling the vault with clean water (not water already pumped out).
     
  • Record the volume of grease removed on a Maintenance Log For Cleaning XLS document
     

The cleaning frequency depends on the individual establishment. Interceptors require cleaning at least every six months. However, frequency depends on the capacity of the device, the amount of grease in the wastewater, and the degree to which the facility has contributed to blockages in the past. Thus, the frequency can range from weekly to every six months.
