What is FOG?

Fats, oils and greases, also referred to as "FOG", come from items such as meat fats, lard, oil, shortening, butter, margarine, food scraps, baked goods, sauces, mayonnaise, and dairy products.  FOG can enter the sewer system from washing dishes containing even residual amounts of these items.  Large amounts of FOG is commonly found in Food Service Establishments (FSEs).  However, FOG is produced anywhere food is prepared such as residential homes and other businesses.

What happens if FOG is not properly managed?Pipe Photo containing FOG

When FOG is poured down the drain, it solidifies and builds up in the pipes. Blockages from the FOG can cause back-ups in the kitchens or basements or can lead to sanitary sewer overflows. These back ups and overflows are a health risk and cause unpleasant odors. Back-ups are expensive and unpleasant to clean up and often must be paid for by you, the business/home owner.

 What can you do?

  • Never pour grease down sink drains, floor drains, or into toilets
  • Scrape grease and food scraps into a can, directly in the trash or into a compost bin for proper disposal
  • Use a strainer in the sink to collect excess food scraps
  • Do not rely on a garbage disposals to get rid of grease or food scraps; they are not trash cans!
  • Don't use chemicals to remove clogs; they can damage the piping system & push material into the main sewer lines
  • Encourage others to help keep FOG out of the sewer system
