What is FOG?

FOG stands for Fats, Oils and Grease and is found or produced in kitchen areas and garages. The main contribution of FOG is from discharge of used grease from cooking processes, but can also be caused by machinery lubricants discharged into floor drains.

Many of the foods we eat contain FOG. These include meats, sauces, salad dressings, deep-fried dishes, cookies, pastries, batters, icings, dairy products, butter and many others. Generally, food scraps washed down the drain also contribute to FOG in the sewers. Grease accumulation in the sewer system causes obstruction by constricting flow of the sewer pipes, and interfering with the normal operation of your community wastewater treatment system.
