Gwinnett County established a fats, oil, and grease (FOG) prevention program in 2000 and adopted an updated ordinance in 2008.

The FOG program operates in accordance with the U.S. Clean Water Act and the Georgia Water Quality Control Act.

The County relies on three full time inspectors to make sure businesses are following the regulations that help protect the environment and other property owners from spills and overflows. In fact, the Department of Water Resources maintains and has jurisdiction over most of the sewer collection system within the county with the exception of Buford, Braselton, and parts of Norcross and Loganville.

The FOG ordinance outlines steps restaurants and food service establishments (FSE)must take in keeping FOG out of the County’s collection system. Putting the FOG program in place has limited the damage restaurants and businesses have caused on the system. Key points the ordinance addresses include:

  • Which types of businesses must have grease traps (also called grease interceptors) to capture FOG at the source
  • Best management practices (BMPs) in kitchens for reducing FOG in the grease trap
  • Details on service and maintenance, such as how often grease traps must be pumped out
  • Record – keeping required to show regular maintenance
  • Consequences of violating the ordinance
