The City's grease control program exists to protect Wichita sewer lines from deterioration and stoppages due to Fats, Oils, and Grease (FOG). FOG includes cooking grease and also comes from meat products (raw or cooked), dairy products, and even some plant products.
All food service establishments which are served by Wichita sewer are subject to Wichita's grease ordinance in Chapter 16.24 of the City's municipal code. "Food Service Establishment" means any facility which cuts, cooks, bakes, prepares or serves food, or which disposes of food-related wastes; including, but not limited to, food courts, food manufactures and packagers, restaurants, grocery stores, bakeries, lounges, hospitals, hotels, nursing homes, churches and schools.
In most instances, all food service establishments must have a grease interceptor.
