What is a grease trap verses a grease interceptor?
A grease trap is an interior small reservoir built into the wastewater piping closed to the grease producing area. This is normally under the sink but also can be located in the floor. The grease trap is used for conditions where space is limited for an external interceptor. Baffles retain the waste water long enough to separate allowing the grease to rise to the surface. The grease and settled solids can be removed and disposed of properly, either in an exterior grease collection tub or in the garbage. The city recommends grease traps to be cleaned nightly but no less than every two weeks. A grease interceptor is an exterior in-ground vault. The vault includes minimum of two compartments with floor between each compartment. These are for larger food service establishments. Interceptors have a minimum capacity of 500 gallons but normally consist of 1000 gallons or more. The city recommends grease interceptors be cleaned monthly but no less than every three months.
