Grease traps are installed for the purpose of minimizing grease in the sewer system. What is true about their effectiveness?

The effectiveness of grease traps is often questioned, particularly in commercial applications, which is why it is important to consider the intricacies of their performance. Grease traps are designed to capture fats, oils, and grease (FOG) before they enter the sewer system, thereby preventing clogs and the potential for sewer overflows. However, there is variability in how well these devices work in different settings, especially in restaurants and other establishments with high grease outputs. In some cases, they may not sufficiently manage the volume of grease generated, leading to ongoing issues with sewer blockages.

This uncertainty in performance can stem from several factors including the size and design of the grease trap, the volume and type of food waste processed, and the maintenance schedule adhered to by the establishment. Consequently, while many see grease traps as necessary, their effectiveness can be debated in various commercial contexts due to these variables.
