Abstract

A grease interceptor and method of use thereof is provided for separating solids, fats, oils, and grease waste ('F.O.G.'), and other particulate matter. The grease interceptor receives waste water in a liquid storage area where solids in the waste water have residence time long enough to gravitationally separate towards the bottom of the liquid storage area and waste that is less dense than water floats to the top of the liquid storage area. A series of features including channels, interrupter plates, and walls can increase the residence time or otherwise improve the separation of waste from the water. In addition, embodiments of the grease interceptor can have tapered access holes that improve visual inspection of the liquid storage area of the grease interceptor.
