Stop Fats, Oils & Grease (FOG) from Clogging Your Pipes

When fats, oils, and grease are dumped into drains, it can cause costly sewer blockages and overflows. Learn more below about fats, oils, and grease control and what you can do to properly dispose of these items.

You've just prepared a nice dinner after a long, hard day. Now, you're looking at that mess at the kitchen sink and dreading the cleanup. It might be tempting to just pour that hamburger grease and cooking oil down the kitchen sink … but, don’t do it!

If you like to dump your leftover food scraps, oils and grease (FOG) down the drain, chances are that you'll pay for it sooner or later. Grease causes sewer blockages and wastewater overflows that damage homes, threaten the environment and cause health hazards. Grease blockages can back up raw sewage into your home, your neighbor's home, a neighborhood park, a nearby yard, or the street.

Grease comes from food items such as:

  • meat fats
  • lard
  • cooking oil
  • shortening
  • butter and margarine
  • sauces
  • dairy products
  • all different kinds of food scraps

The grease from these food items will stick to the inside of sewer pipes. It can affect the pipes on your personal property, including the sewer lateral that leads to our public sewer main—and it can affect the public sewer main itself. In time, grease builds up and can block an entire pipe. If you use your garbage disposal to get rid of other food waste such as coffee grounds, eggshells, and other non-fatty foods, these broken-down pieces of grit can get trapped in the greasy buildup and create more problems. And remember, do not flush any fats/oils or grease down your toilet, either—you have one sewer lateral that takes all of this waste from your property to the public main, and you want to protect it from clogging!

You might think it's okay to use your garbage disposal to shred leftover meat or cheese or other fatty foods, but shredding doesn't get rid of the fats that create grease. And, what about those detergents that claim to dissolve grease? They just pass the grease down the line to cause problems elsewhere.
