Which technique is useful for understanding how infiltration water flows during maintenance activities?

• A. Hydrostatic testing
• B. CCTV inspections
• C. Smoke testing
• D. Pressure washing

Answer: (C)

Smoke testing is a valuable technique for understanding how infiltration water flows because it allows maintenance personnel to visualize the movement of air and water through a collection system. When smoke is introduced into a sewer system, it will fill the pipes and escape at points of infiltration, effectively indicating where water may be entering the system unnecessarily. This method helps identify vulnerabilities in the system, such as cracks in pipes or faulty joints, where infiltration water can compromise the integrity of a sewer line. This visualization aids in pinpointing problem areas that may require further investigation or maintenance, ultimately contributing to more effective and efficient repairs. Smoke testing not only reveals the presence of infiltration but can also help in assessing the overall condition of a sewer system during maintenance activities.
