Which operation removes material from a sewer by cutting through debris and solids?

• A. Brushing.
• B. Pumping.
• C. Sweeping.
• D. Cutting.

Answer: (D)

Cutting is the operation that physically cuts through debris and solids inside a sewer to break up blockages and remove them. This method directly targets solid obstructions, enabling the material to be cleared and flow to be restored. Brushing cleans surfaces and helps remove loose buildup, but doesn’t break through solid masses. Sweeping collects loose debris, not solid plugs. Pumping removes liquid and some suspended solids but can’t cut through a solid blockage. So cutting best matches the goal of removing material by cutting through debris and solids.
