Preventing FOG From Entering The Plumbing

Food Service Establishments


  • Train employees how to manage FOG.
  • Post signs to remind staff about proper FOG management procedures.
  • Dry wipe dishes before washing to remove grease and dispose of the grease in the garbage. - Clean grease spills with absorbent material and then dispose of the material in the garbage.
  • Do no discharge FOG down drains, sink, floor drains, toilets, or storm drains, and never dispose of sewage or kitchen waste into a storm drain.
  • Empty grease containers before they are completely full to prevent overflows. Collect and empty grill scrapings and fryer vat grease into a leak-proof grease recycling container that can be tightly sealed, ad recycle waste cooking oil.
  • Dispose of food waste by recycling and/or solid waste removal to divert it from grease traps and interceptors.
  • Avoid or limit the use of garbage disposals. The food particles can fill up a grease trap.
  • Use detergents instead of soap; soap contains oil. Use a three-sink compartment dishwashing system, including sinks for washing, rinsing, and sanitizing.
  • Cover outdoor grease and oil storage containers, and use a licensed hauler to dispose of spent grease.
  • Routinely clean kitchen exhaust system filters.
  • Regularly check grease control device and ensure they're accessible for maintenance and inspection. Clean interceptors with a capacity of 100 gallons or less weekly or more frequently if needed. Never put FOG removed from the grease control device into the sewer system.
  • If there is little or no FOG in the grease control device, verify that is installed correctly.
