Grease interceptors typically use gravity and temperature changes to separate grease and oil from the water. As FOG enters the interceptor, items are cooled down resulting in separation, only allowing water to enter the sanitary sewer line.
The purpose of this checklist is to offer a general format to follow during inspections. All grease traps must be inspected and listed on this form. Return this form with the annual reporting form. Is there a Grease Trap/Interceptor inside the building?
Gravity Grease Interceptor Inspection Examples 1.) Obtain the FOG and/or solid levels using a “Sludge Judge” or a simple rod with a flat bottom piece to feel the accumulation levels within the recognized areas of separation, flotation and settling. 2.) Measure the depth of the grease.
