Fats, Oils and Grease (FOG) are generated at food service establishments (FSEs) as a byproduct of food preparation activities. When FOG enters the sewer system it begins to cool and solidify, reducing conveyance capacity and blocking flow. Often time this leads to sewer overflows and spills which put the health and safety of the public at risk. Grease interceptors have played an important role in preventing accumulated FOG from damaging the public infrastructure by collecting it at the source. Grease interceptors, when combined with Best Management Practices (BMPs), will significantly reduce the amount of FOG entering the sewer system.
