Fats, Oils and Grease Disposal

Fats, oils, and grease (F.O.G.) resulting from food preparation can build up in sewer pipes and cause costly blockages and backups and sewage overflows to private and public property. View a video of a FOG-clogged pipe.

Read our Frequently Asked Questions.

You can help fight F.O.G.

Sources of F.O.G. include:

  • Gravy, sauces and soups
  • Cooking oil, butter, shortening, lard and margarine
  • Milk, cream, sour cream and mayonnaise
  • Food scraps
  • Oil from cooked meats

Tips to keep your drains fat-free:

  • Pour fats, oils and grease into a covered disposable container—such as glass, plastic or a sturdy Ziploc bag—that will seal and hold F.O.G. waste. Store it in the freezer and then put it in the trash after it has hardened.
  • Use paper towels to wipe greasy dishes before washing. Put the paper towels in your food waste cart.
  • Use sink strainers to catch food waste when washing.
  • Put food scraps in compost bin or in the trash.

Remember that F.O.G. waste cannot be recycled or composted and must be enclosed in a container and put in the trash. The benefit of throwing F.O.G. waste in the garbage to protect pipes and water outweighs the cost of disposing possible recyclable containers in the garbage.
