Abstract: A grease trap and management tank is disclosed herein. The trap has two compartments, a forward and rear compartment separated by two baffles so that grease and oils may rise and solids and sludge settle out and not be introduced into a sewer line. An ultra sonic monitoring device is also shown with local record keeping and alarm capabilities as well as remote management options through phone line, wireless or internet communications. Servicing may be scheduled according to this data to prevent any problems with the trap. The grease trap also features an access door that opens to reveal the entirety of the grease trap for easy cleaning. Since the dimensions of the tank do not exceed the width and height of standard doorways, installation indoors is greatly simplified. Along with adaptable risers, the trap may be made of metal, plastic or any other suitable material, installed indoors and mounted in concrete or any other suitable construction material.
