Which term is described as required in kitchens, garages, and restaurants?

• A. Grease Traps
• B. Outfall Line
• C. Vent Pipe
• D. Profile Plan

Answer: (A)

Grease traps are essential devices designed to intercept fats, oils, and grease from wastewater before it enters the sewer system. In kitchens and restaurants, as well as garages where vehicles are serviced, large amounts of oily waste can go down drains, risking clogs, backups, and sewer odors. A grease trap works by slowing and separating the mixture: grease, being lighter than water, floats to the top while solids settle at the bottom, leaving relatively grease-free water to continue on to the sewer. Because grease accumulates quickly, these traps must be sized for the facility and cleaned regularly to remain effective. Other drainage components like vent pipes or outfall lines serve different roles in plumbing, and a profile plan is just a drawing of the layout rather than a device that treats wastewater.
