Before installing or replacing a grease interceptor, consult these resources:
Grease interceptors will need a plumbing and an SUDP review.
In a restaurant or commercial kitchen, a change to the type of cuisine served, an increase in seating capacity, or a change in the cooking appliances could all have an impact on grease interceptor sizing.
For projects that require a grease interceptor, make sure to connect all fixtures in the kitchen and food prep areas to the grease waste sewer line, which is then directed to the appropriately sized grease interceptor, prior to connecting to the domestic sanitary sewer system for the building. Bar areas, beverage stations, restrooms, and any other area that is not in the kitchen or intended for food prep should NOT be directed to the grease waste sewer line, but rather connected directly to the domestic sewer system for the building.
