The record log of a hydraulic cleaning operation should include which item?

• A. Feet of rod used
• B. Type and amount of material removed from a downstream manhole
• C. Camera malfunctions
• D. All of the above

Answer: (B)

During hydraulic cleaning, debris is pushed toward a downstream manhole and collected there. The most important thing to document in the record is the type and amount of material removed from that downstream manhole. This directly shows what was cleared from the system, supports proper waste disposal and regulatory reporting, and helps assess how effective the cleaning was and what may need attention in the future.

Recording feet of rod used would apply to mechanical cleaning, not hydraulic cleaning, so it doesn’t reflect the outcome of a hydraulic operation. Camera malfunctions, while relevant to equipment performance, don’t describe the cleaning result or disposal needs, so they aren’t the essential item for the log. Therefore, documenting the material type and quantity removed from the downstream manhole best fulfills the purpose of the record.
