Managing grease to protect your business and your plumbing
Every commercial food service establishment produces waste products of fats, oils, and grease (FOG). Every restaurant and commercial kitchen is required to take steps to prevent FOG from going down the drain and entering the sewer system. Fats, oils, and grease is a major contributor to clogs in the city sewer system and grease build up at the LOTT Budd Inlet Treatment Plant. Pipe blockages caused by FOG can also cause sewage backups into restaurants and commercial kitchens, leading to business shutdowns and costly repairs.
FOG comes from more than just grease, it also comes from butter, condiments, dressing, cooking oils, and dairy products. Even if you can't see FOG in hot soapy water, it's still there. As FOG goes through the sewer system, it cools, becomes a solid, and coats sewer pipes which in turn causes blockages throughout the city. This causes sewage spills, manhole overflows or backups in homes and businesses.
Food service establishments are required to install and properly maintain grease traps and take other actions to prevent fats, oils, and grease from entering the sewer system. Click on one of the links below for more information about those requirements.
