Purpose of a Grease Trap and Grease Interceptors?

F.O.G.S. Gravity Device

It is mandatory for most food servicing establishments (FSE) to install a F.O.G.S. (Fats, Oils, Grease and Solids) separator device also known as a grease trap or grease interceptor in the city of Los Angeles in efforts to reduce the amount of F.O.G.S. contamination entering the city waste water line. Without having the proper regulations that would reduce the amount of fats, oils, grease and solids waste going into the city sanitation these waste will build up on the walls of the pipes decreasing the pipe's capacity and ultimately clogging the pipes fully causing sewer waste to overflow. Spillage of sewer waste is not only costly to clean up; it can also release bacteria and hazardous waste that is hazardous human health. Therefore, in order to substantially reduce the amounts of F.O.G.S. waste entering the city sewer; it became mandatory for FSE’s to acquire a grease trap or an interceptor.

Grease Trap VS Grease Interceptor

The main difference between the two is the size. Grease interceptors are usually made out of concrete located outside the establishment ranging in sizes of 500 gallons and above. On the other hand, grease traps are significantly smaller in size ranging from 5 gallons up to 100 gallons located beneath the sink.

What should we install; grease trap or a grease interceptor?

Decisions of what device to install will be determined by the city FOGS program officer (contact the city). Most likely, cities tend to require FSE’s to install a large in ground grease interceptor located outside the premises unless there is no other possibilities that one can be installed. Before installing a grease trap or interceptor contact the city to determine their requirements. The cost of installing grease trap or interceptor can be expensive and installing a grease device without knowing the city requirements can be very costly mistake.
