Collier County Public Utilities, Industrial Pretreatment Program

Grease Trap and Interceptor Maintenance (Food Service Establishments)

The Collier County Public Utilities Food Service Establishments page states: "All food service establishments must operate and maintain grease removal devices, such as grease traps or interceptors. Cleaning and service records must be retained for a minimum of three years and made available for County inspection upon request." Per that page, accumulated grease and food waste must be pumped at least every 30 days from a grease trap (usually inside the building or under the sink) and at least every 90 days from a grease interceptor (usually below ground outside), every cleaning must be documented for inspection by County staff, grease waste may be disposed of only at approved treatment facilities, and no chemicals, enzymes, emulsifiers, bacteria or other grease additives may be used without county approval. The Industrial Pretreatment Program page states that the program is authorized by the Florida Department of Environmental Protection and Chapter 134, Article IX of the Collier County Code of Ordinances, and that the program inspects each permitted facility at least once a year. Installing a new grease trap is a separate building-permit item ($50.00 per grease trap under Resolution No. 2025-231 § P.7).
