Fats, Oils and Grease (FOG)

WHERE DO FATS, OILS AND GREASE COME FROM? 

Fats, oils and grease are derived from plant and animal sources and are a by-product of cooking. Restaurants, condominiums, apartment buildings, homes, schools, churches, food-processing plants, shopping malls, caterers, hospitals, retirement/assisted living facilities and many more locations all produce fats, oils and grease.
 

WHY ARE FATS, OILS AND GREASE A PROBLEM?

If poured down the drain, fats, oils and grease can adhere to pipe walls. This buildup can restrict or completely block pipes, resulting in rancid odors or messy costly sewer backups in your home or overflows into your neighborhood.
 
Fats, oils and grease are the number one cause of sewer blockages in homes. These blockages can result in sanitary sewer overflows that pollute the environment and damage properties.
 

EVERY HOUSEHOLD PLAYS AN IMPORTANT ROLE IN PREVENTING NEIGHBORHOOD SEWER BLOCKAGES

By following simple clean-up measures while cooking, you can help eliminate unwanted grease. Your efforts will greatly help to reduce sewer maintenance and operation expenses, as well as reduce the public health risks associated with sanitary overflows.
