Fats, Oils, and Grease (FOG)

Fats, Oils & Grease (FOG)

  • Grease blockages in sewer lines are common causes of overflows and basement backups.
  • Grease is a byproduct of cooking and comes from meat fats, oils, shortening, butter, margarine, food scraps, sauces, and dairy products.
  • Correcting a blockage is expensive. If it occurs on your property, it will be the owner’s responsibility to contact a plumber to have it cleared.
  • Sewage overflows can result in serious harm to the environment.

Help Prevent Blockages & Backups by Disposing of Grease Properly

Do not pour grease, fats, and oils from cooking down the drain.
  • Collect the grease in a metal can (soup cans work great).
  • Once the grease has cooled and solidified, place it in the trash for disposal.

Common Myths about Grease

Garbage disposals do nothing to protect your drain lines from accumulating grease.
  • Dishwashing detergents do not protect your lines from grease buildup. While it is true that they initially break up grease, they eventually lose this ability and grease will begin to accumulate in sewer lines.
  • Chasing grease down the drain with hot water only causes the grease to buildup elsewhere.
