The Utilities Department wants to remind citizens about the proper ways to dispose of fats, oils and grease (FOG), especially as families begin to cook big holiday meals.   

Cooking results in excess FOG and if it isn't disposed of properly, it can end up in the City’s wastewater lines. FOG down the drain means sewer backups, costly repairs and it can harm the environment. Find out the steps you can take to stop the FOG clog!


Trash F.O.G.

The Holidays are Near, Keep Wastewater Lines Clear!

Fats, Oils, & Grease clog wastewater lines.

Keep the drain clear of Fats, Oil and Grease. Did you know? Nearly half of all sewer blockages annually are caused by Fats, Oil, and Grease (FOG)?

All cooking oils, butter, dairy products, bacon fat and cooking grease should be absorbed with a paper towel and tossed in the trash.

You can also collect Fats, Oils, and Grease in a grease container, cool it, scrape it, and trash it.

Grease Containers

When Fats, Oils, and Grease (FOG) aren’t disposed of properly, it can end up in the City’s wastewater lines, which can cause sewer backups. That's why the City is giving out free Grease Containers.

FOG Diagram

In the Diagram above, the thick yellow layer is FOG. When it goes down the drain, it builds up over time, restricting the flow of wastewater. If it happens in your home, you pay for it. If it happens in City drains, your whole neighborhood will have drainage problems. City crews must use special pressure washers and vacuums to remove the FOG.
