Fats, Oils & Grease (FOG)

You may not be aware of it, but every time you pour fat, oil, or grease (FOG) down your sink (e.g., bacon grease), you are contributing to a costly problem in the sewer collection system. FOG coats the inner walls of the plumbing in your house as well as the walls of underground piping throughout the community. Over time, these greasy materials build up and form blockages in pipes, which can lead to wastewater backing up into parks, yards, streets, and storm drains. These backups allow FOG to contaminate local waters, including drinking water. 

Public Health Hazard

Exposure to untreated wastewater is a public health hazard. FOG discharged into septic systems and drain fields can also cause malfunctions, resulting in more frequent tank pump-outs and other expenses. Communities spend billions of dollars every year to unplug or replace grease-blocked pipes, repair lift stations, and clean up costly and illegal wastewater spills. 


Here are some tips that you and your family can follow to help maintain a well-run system now and in the future:

  • Never:
    • Pour fats, oil, or grease down the house or storm drains. 
    • Dispose of food scraps by flushing them.
    • Use the toilet as a waste basket.
  • Always:
    • Scrape and collect fat, oil, and grease into a waste container such as an empty container, and dispose of it with your garbage.
    • Place food scraps in waste containers or garbage bags for disposal with solid wastes.
    • Place a wastebasket in each bathroom for solid wastes like disposable diapers, creams and lotions, and personal hygiene products including non-biodegradable wipes.
