How can a closed circuit television unit with video tape help to evaluate the condition of a wastewater treatment system?

• A. To study the effectiveness of cleaning techniques under various conditions in the collection system
• B. Chemicals can be applied for root control
• C. Service lines to homes can be inspected
• D. TV cameras can remove stoppages

Answer: (A)

A closed-circuit TV inspection is used to look inside the sewer lines and see what the interior condition is like, including buildup, blockages, and pipe defects. When applied to evaluating the system, this tool lets you visually verify how well cleaning techniques work under different conditions in the collection system—seeing how much debris is removed, how clean the pipe is after treatment, and whether any remaining obstructions or damage persist. It’s about using the video view to judge the effectiveness of cleaning methods and the resulting condition of the pipes. The other options don’t fit as well. Chemicals for root control aren’t delivered or evaluated by a TV unit, since CCTV is an inspection tool. While cameras can inspect service lines to homes, the question focuses on evaluating the wastewater system’s condition, which is best served by using CCTV to assess cleaning effectiveness in the collection system. And TV cameras don’t remove stoppages themselves; they assist in locating and diagnosing issues, not clearing them.
