FOG is an acronym for Fats, Oils and Grease that are deposited into the sanitary sewer system. FOG comes from meat fats in cooking and food scraps, cooking oil, shortening, lard, butter and margarine, gravy, and food products such as mayonnaise, salad dressings, sour cream and other foods high in fat.
The Impact of FOG
FOG poured down kitchen drains accumulates inside sewer pipes. When FOG enters the sanitary sewer system, it can harden in the pipe and cause blockages resulting in Sanitary Sewer Overflows (SSO’s). FOG also reduces the capacity of the system and is detrimental to the wastewater treatment process. The result is that a considerable amount of money is spent every year removing the build-up of fats, oils, and grease.
Manholes can overflow into parks, yards, streets, and storm drains, allowing FOG to contaminate local waters, including drinking water. Exposure to untreated wastewater is a public-health hazard.
How to Correctly Dispose of FOG
Pour and wipe grease from cooking into a can, let it cool, and throw it in the trash.
