Fat, Oil & Grease (FOG)

Fat, oil, and grease (FOG) are byproducts of food preparation and cooking, and the majority of FOG enters the sewer system during cleanup when washing dishes, cookware, etc.  It’s common to only think of “fryer oil” when you hear of oil and grease but fat, oil, and grease are present in a large variety of foods including:

  • Cooking oils
  • Dairy
  • Desserts
  • Gravy
  • Mayonnaise
  • Meats
  • Miscellaneous food scraps/residue
  • Salad dressings
  • Sauces

The Problem:

  • FOG accumulates in sewer pipes and lift stations where it eventually causes sewer blockages and sanitary sewer overflows. 
  • FOG buildup can also cause raw sewage to backup into homes and businesses resulting in significant cleanup costs.  
  • FOG will build up in your own private sewer lines as well if care is not taken to minimize the amount of FOG and food solids discharged down the drain.

The Solution:

  • Put it in the trash, not down the drain!
  • Wipe your plates, cookware, and utensils with paper towels instead of rinsing food scraps and residue into the garbage disposal.
  • Collect meat grease/drippings in a disposable container (small can, yogurt cup, etc.) then discard in the trash after it cools.
