Which of the following statements about grease traps is accurate?

The chosen statement accurately reflects the importance of grease traps in wastewater management. Grease traps are specifically designed to capture and reduce grease, fats, and oils from wastewater before they enter the main sewage system. They function by allowing waste to flow through a tank where lighter substances rise to the top, forming a layer of grease that can be regularly removed, thereby preventing clogging and environmental issues associated with untreated wastewater.

While it's true that for some designs, grease traps can effectively minimize grease in the wastewater, other statements may not comprehensively represent regulations or best practices associated with grease trap usage. For instance, not all grease traps need to be constructed from concrete; they can also be made from various materials, including plastic or fiberglass, depending on the required capacity and application. Additionally, residential grease traps do not necessarily need to exceed a certain volume, and the frequency of maintenance can vary based on the level of grease production, meaning that annual cleanings might not be universally applicable.
