Grease Interceptor Program

Never dump grease down the drain! Grease is a solid waste and goes in the trashcan!


Basic Grease Interceptors (Traps) Sizing Requirements:

The City of Cumming Utilities Ordinance requires that all  food service establishments install and maintain a properly sized grease interceptor (trap). Each grease trap must be constructed to allow for 15 gallons per seat. For example, a food service establishment with 200 seats would be required to install at least: (200 seats) x (15 gallons per seat) x (24 Hours of Operation /12) x (1.0 Loading Factor) = 6000 gallon grease trap. In addition, no single grease trap shall be smaller than 1000 gallons or larger than 3,000 gallons. If more than 3,000 gallons of capacity is  required, multiple grease traps may be utilized.
