Which component primarily serves to prevent grease buildup in a sewer system?

• A. Interceptor tank
• B. Grit chamber
• C. Wet well
• D. Lift station

Answer: (A)

The interceptor tank is designed specifically to prevent grease and oil from entering the sewer system, thereby reducing the risk of buildup in the piping and treatment facilities. These tanks work by allowing grease and oil, which are less dense than water, to float to the surface, where they can be skimmed off. This is crucial because grease buildup can cause blockages, leading to backups and overflows, which can pose significant challenges for wastewater management and potentially harm the environment. In contrast, components like grit chambers are designed to remove heavier solids or grit from wastewater, while wet wells and lift stations function to facilitate the movement of wastewater by storing it temporarily and pumping it up to a higher elevation for transportation through the system. Each of these elements has a distinct purpose, making the interceptor tank the appropriate choice for managing grease specifically.
