The purpose of an interior or exterior grease interceptor is to remove grease or oil from sewage prior to discharge to the public sanitary sewer. These interceptors serve as a small flotation chambers where grease rises to the water surface and is retained, while the clearer water underneath is discharged. The use of word “interceptor” is interchangeable with the word “trap.”
