Fats, Oil, Grease (FOG)

Fats, Oils, and Grease (FOG) are generated during food preparation. When water is used to clean kitchen, FOG is washed down the drain where it cools and separates. The separated FOG accumulates in and sometimes clogs drains, sewer pipes and collection systems, and wastewater treatment facilities.  FOG clogs damage wastewater infrastructure, including home plumbing.

MSD’s FOG Management Policy requires Food Service Establishments to use grease traps and/or grease interceptors to prevent FOG clogs.  These devices must be certified annually by an MSD approved Certified Grease Waste Hauler or Plumber.
