Which of the following is not a component of sewer system maintenance?

The correct choice is the installation of monitoring software, as it does not directly pertain to the physical maintenance of a sewer system. Sewer system maintenance primarily focuses on activities that ensure the system operates efficiently and without obstruction or failure. Routine inspections are essential for identifying potential issues before they escalate, while emergency response to leaks is critical for minimizing damage and ensuring public safety. Clearing blockages is a physical maintenance task aimed at preventing backups and ensuring smooth flow through the sewer lines.

While monitoring software may be beneficial for overall system management and performance tracking, it is not categorized as a traditional maintenance activity. Instead, it serves as a tool that can augment maintenance efforts but does not involve direct physical intervention or upkeep of the sewer system itself.
