Fats, Oils and Grease (F.O.G.)
What is F.O.G.?
FOG refers to fats, oils and grease from food preparation and kitchen clean up. It is found in food items such as:
- Meat fats
- Food scraps
- Lard/shortening
- Baking goods
- Butter/margarine
- Cooking oil
- Sauces
- Dairy products
- Salad dressings
When these and other similar items are regularly poured into sinks, garbage disposals, toilets or other household drains, they eventually cool, harden and stick to the sewer pipes, forming a blockage and can cause sewer back ups which may result in:
- Clogged drains or toilets
- Raw sewage backing up into your home
- Raw sewage overflowing into the environment
- Expensive clean up, repair and replacement of damaged property
- Higher wastewater system operation & maintenance costs
- Unpleasant odors
- Potential public health risks
Sewer repairs and associated clean up activities can cost homeowners thousands of dollars.
How You Can Prevent F.O.G. Damage
You can avoid expensive sewer back ups, plumbing emergencies and repairs while helping protect the local water supply by following a simple list of DO’s and DON’Ts when disposing of fats, oils and grease:
- DO pour fats, oils or grease into a can until they cool. Coffee or soup cans work well. They can be stored for reuse until full when it can be thrown in the trash.
- DO wipe pans or dishes that contain fats, oil or grease with a paper towel before washing and throw the used paper towel in the trash.
- DO place a strainer in the kitchen sink drain to catch food scraps and other solids and regularly empty the strainer in the trash.
- DO encourage neighbors to help keep fats, oils and grease out of the sewer system.
- DO maintain an approved grease trap where food is processed.
- DON’T pour cooking oil, pan drippings, bacon grease, salad dressings or sauces in the sink or toilet.
- DON’T run water over dishes, pans, fryers or griddles to wash oil and grease down the drain.
- DON’T use cloth or rags to scrape plates or oily dishware. When you wash them, the grease will end up in the sewer.
- DON’T use a garbage disposal or food grinder on fatty or greasy food. Grinding food before rinsing it down the drain does not remove the fats, oils or grease, it just makes the pieces smaller. Even non-greasy food scraps (salads, etc.) can plug sewer lines.
- DON’T use chemicals to remove grease clogs; they can damage the piping system.
The picture shows a sewer pipe that, over time, has become clogged with grease. As you can imagine, these clogs can make it difficult for the sewers to operate properly, leading to messy back-ups in homes and expensive repairs for you and for Village staff. The Village of Libertyville is asking you to help avoid these problems by properly disposing of fats, oils and grease.
The Village Board passed an ordinance regulating the disposal of fats & greases; and to promote proper disposal of fats & greases and aid in preventing sanitary sewer blockages. Section 25-106 Grease, Oil and Sand Traps. All establishments involved in the preparation of food for commercial purposes shall provide grease interceptors or traps.
