Grease traps/ interceptors are required to receive the drainage from fixtures and equipment from grease-laden waste located in food preparation areas, such as in restaurants, hotel kitchens, hospitals, school kitchens, bars, factory cafeterias, clubs, and other institutions. Grease traps/interceptors should receive waste only from fixtures that allow fats, oils, or grease to be discharged. Dishwashers should only be included when necessary in order to capture grease that cannot be otherwise contained.
