Fats, Oils and Grease (FOG) Information

What is FOG?

FOG stands for Fats, Oils and Grease.

Did you know that approximately 30 percent of the foods we eat are considered FOG?

Foods such as meats, sauces, gravies, salad dressings, deep-fried dishes, pastries, cheese, and butter are considered high in FOG.

Why Does It Matter?

By disposing of fats, grease and oils improperly, these materials can build up and create clogs in your sewer pipes and result in costly repairs.

FOG can also build up in the Town wastewater systems and create clogs, damage infrastructure, cause overflows and harm the environment.

Initially, FOG flows with little problem when mixed with hot water. But once it cools in the sanitary sewer pipes, it starts to harden and stick to the sewer lines.

When the solids build up over time, lines get blocked, which can cause nasty sewer spills. These spills can erupt anywhere there is a sewer line and at any time. Sewage may overflow in your yard or even back up into your house or business through sewer lines.

In addition, blockages can create costly plumber bills.

The only way to prevent blockages is to keep the fats, oils, and greases out of the sewer lines.

What Can I Do?

  • Cool down your cooking oil, grease, and fat and pour them into a covered container. These covered containers can be placed in the trash can with your regular garbage. Please do not put oil and grease down the drain.
  • Avoid using the garbage disposal excessively. Do not put food scraps down the drain. Instead, scrape food scraps from your dishes into the garbage.
  • Use a paper towel to "dry wipe" grease and oil from dishes and cookware before you wash them. The wipe can be discarded with your regular garbage.
  • However, do not use cloth towels or rags to wipe plates or to clean greasy, oily dishes. When you wash the cloth, the grease will end up in the sewer.
Cease the Grease Image
  • Prewash dishes and pans with cold water before putting them in the dishwasher. Cover the sink drain with a catch basket and dispose of contents in the garbage. Do NOT rinse with hot water. Hot water melts the fats, oils and grease off the dishes and into the sewer pipes. Later, the hot water will cool and the FOG will clog the pipes.
  • Small amounts of used cooking oil should be reused as much as possible, then poured into a disposable container.
  • Large amounts of used cooking oil should be recycled through the Montgomery Regional Solid Waste Authority.
