What Is a Grease Trap?
A grease trap (also called a grease interceptor) is a plumbing device designed to capture fats, oils, and grease (FOG) before they enter the municipal sewer system. Every food service establishment in the United States that produces FOG is required to have one installed and properly maintained. Grease traps prevent sewer blockages, overflows, and environmental contamination caused by FOG buildup in pipes.
FOG compliance isn't just a suggestion — it's the law. Municipalities across the country enforce strict regulations because grease buildup is the leading cause of sanitary sewer overflows (SSOs) in the US. Non-compliance can result in hefty fines, permit revocations, and even forced closure of your establishment. Requirements vary significantly between cities and are tracked in detail in our database.
