Which of the following is NOT a function of a grease trap?

A grease trap’s primary functions are to separate solids from liquid waste, reduce the amount of grease in wastewater, and prevent grease buildup in plumbing systems. By design, grease traps are intended to intercept grease and fats before they can enter the wastewater disposal system, thereby protecting the plumbing and the septic system from blockages caused by grease accumulation.

In terms of function, grease traps typically operate by allowing grease to rise to the surface and separate from other waste, effectively removing solids and reducing fatty substances in the wastewater. However, they are not meant for long-term storage of wastewater. In fact, grease traps need to be regularly maintained and emptied to function effectively.

Thus, the correct option identifies an inaccurate description of a grease trap's role, as storing wastewater for extended periods falls outside the intended purpose of a grease trap and would hinder its efficiency in managing grease and solids in wastewater.
