Supermarkets, Restaurants, Hospital Cafeterias, and School Cafeterias are required to install grease traps to handle waste from food preparation areas. Grease traps should be inspected monthly and must be cleaned by a licensed septage hauler whenever the level of grease is 25% of the effective depth of the trap, or at least every three months, whichever is sooner.

Contact your local Board of Health for a listing of licensed septage haulers able to pump out grease traps. Pumping and Inspection results are sent to the local Board of Health. It is the system owner's responsibility (restaurant, supermarket, cafeteria, hospital) to ensure that grease traps are pumped regularly and maintained. See 310 CMR 15.230  for the Title 5 regulatory requirements as they relate to grease traps.
