Best Management Practices for Fats, Oils and Grease


Residual fats, oils and grease (FOG) are by-products of food preparation. Typically, FOG enters a facility’s plumbing system from ware washing, floor cleaning, and equipment sanitation. Sanitary sewer systems are neither designed nor equipped to handle the FOG that accumulates on the interior of the municipal sewer collection system pipes. Severe accumulations of FOG can lead to sewer overflows that expose the public to raw sewage and the potential for infection from contact with sewage. The best way to manage FOG is to keep the material out of the plumbing systems. The following are Best Management Practices (BMPs) for proper FOG management.
