Fats, Oils & Grease

Owlbert pointing at kitchen sink.Fats, Oils and Grease (FOG) are the liquid and solid residues leftover from cooking many foods. From used cooking oil to bacon drippings, salad dressing, cake batter and food scraps, many foods contain FOG.

The Problem with FOG

When poured down or disposed of in the sink, FOG solidifies and clings to the insides of your pipes or the City’s sewer lines. This can cause a sewer backup in your home or neighborhood, called a Sanitary Sewer Overflow, or an SSO. If it occurs in your home, you’re responsible for the repair and cleanup. If it occurs in your neighborhood, it could result in harm to wildlife as well as costly repair and cleanup for the City.


How to Properly Dispose of FOG

  • Soak up small amounts of grease, such as bacon drippings, with a paper towel and throw it in the trash.
  • Wipe pans and plates with paper towels to remove residues before scrubbing them clean.
  • Use a food strainer to prevent food scraps from going down the drain. Use your garbage disposal sparingly.
  • Place cooled, solidified FOG in a container that you can seal and store easily. Trash it when full.
  • Compost food waste for use in your landscape. Learn how.

Recycle Your Cooking Oil 

Anyone can participate in the North Central Texas Council of Government’s regional cooking oil recycling program. Find a drop off location near you.

If you live in a single-family home, call Environmental Waste Services at (972) 769-4150 to schedule a free pickup of one gallon or more of cooking oil.

Store used cooking oil in a sturdy, screw-top container. Watch this video to learn how to collect and transport it. Recycled cooking oil is made into biofuel.


Protect Your Toilet PipesOwlbert standing on top of a toilet.

Only flush the “3 P’s:” pee, poo and paper (toilet paper only). Everything else belongs in the trash, including “flushable” wipes. They don’t break down like toilet paper. Instead, they tangle with each other and with FOG in sewer pipes, causing “fatbergs.” If wipes make it to the wastewater treatment plant, they damage equipment and slow important processes. 

Feminine hygiene products and personal care products, like cotton swabs, dental floss and contact lenses,
also belong in the trash.
