Fats, Oils & Grease (FOG) OverviewFOG 1

All food service establishments that are connected to public sewers must have an approved grease system, such as grease traps, interceptors and other devices that keep fats, oils, grease (FOG) and food debris out of sewer pipes.

FOG is a problem for food service establishments, as FOG can buildup and clog sewer pipes and cause costly overflows and backups within businesses. It is bad for business and bad for public health and the environment.

When fats, oils or grease (FOG) enter the sewer lines, it cools, solidifies and sticks to the insides of the pipes, trapping food particles and other debris. Over time, this mass continues to grow until it obstructs the flow of wastewater and causes sewage to back up.

Additional Information

Additional information is located in the City’s FOG Brochure at Fats, Oils, and Grease Booklet
