What is the purpose of a grease trap?

The purpose of a grease trap is to intercept and retain grease from sewage or wastewater. Grease traps are specifically designed to capture fats, oils, and grease (often referred to collectively as FOG) that are discharged from kitchens and food service establishments. These substances can cause significant blockages in sewer systems and contribute to environmental pollution when they enter wastewater systems without treatment.

By retaining these materials, grease traps help prevent them from flowing into the wastewater treatment system, ensuring more efficient operation and reducing maintenance needs for the plumbing system. Proper installation and maintenance of grease traps are essential to their effectiveness, as they must be regularly cleaned to continue functioning properly.

In contrast, other options highlight different functions that are not related to the primary role of a grease trap. The storage of waste materials underground refers to septic tanks, while recycling water relates more to systems designed for gray water reuse. The removal of solid waste generally describes the role of a septic system or sewage treatment plant rather than a grease trap.
