Grease Traps Catch Basins
A grease trap or catch basin is a receptacle that kitchen wastewater flows through before entering the sanitary sewer lines. This receptacle captures, or "traps" grease. How? Grease, the industry term for animal fats and vegetable oils, is 10 to 15% less dense, or lighter than water. Grease is also immiscible with water, which is to say it does not mix with water. Thus, grease and oils float on water. When kitchen wastewater flows through a grease trap, the grease and oils rise to the surface and are trapped inside the receptacle using a system of baffles. The captured grease and oils fill the trap from the top down, displacing "clean" water out of the bottom of the trap and into the sanitary sewer line. This is why you see a grease "mat" when observing a grease trap. When a significant layer of grease has accumulated, the trap must be cleaned out as the grease will impede the flow of drain water from you kitchen sink.
