How grease traps and interceptors work
Grease traps and interceptors separate grease and oils from wastewater. A grease trap slows down the flow of hot greasy water allowing it to cool. As the hot water cools, the oil and grease separate and float to the top of the trap.
The cooler wastewater collects on the other side of the interceptor's baffle and from there exits into the sewer system, leaving fats, oil and grease in the interceptor.
Small indoor grease traps are usually located in the floor near the sink or rear exit. Large outside grease traps are located a few feet from the outside of the building.
