What is a grease trap interceptor?
An interceptor is a vault with a minimum capacity of 750 gallons that is located on the exterior of the building. The vault includes a minimum of two compartments, and flow between each compartment is through a 90 fitting designed for grease retention. The capacity of the interceptor provides adequate residence time so that the wastewater has time to cool, allowing any remaining grease not collected by the traps time to coagulates and rise to the surface where it accumulates until the interceptor is cleaned.
