Restaurants and food service operations rely on grease traps in their drainage systems to separate and contain cooking grease from wastewater before the grease can flow into the main sewer and clog the pipeline.

When grease traps become full, a licensed and experienced hauler of liquid waste will pump the grease trap and haul the waste to an approved processing site. 

When grease traps are full, the connected sewer and drain lines may back up and halt all drainage throughout the building. That is never a pretty sight or smell. In fact, many plumbers say that grease traps smell worse than sewers themselves, so it is never good for business when those terrible odors begin wafting through a restaurant or institutional dining facility.
