Why should an operator be present during the construction of a new treatment plant?

An operator's presence during the construction of a new treatment plant is vital to become familiar with the plant before it begins operation. Being involved in the construction phase allows the operator to gain a comprehensive understanding of the layout, the operational processes, and the specifics of the equipment being installed. This firsthand experience is crucial because it prepares the operator to address operational issues effectively once the plant is online. Understanding the intricacies of the facility, including system configurations and potential challenges, equips the operator with the knowledge necessary to manage the plant efficiently and ensure compliance with regulatory requirements from its first day of operation.

The other options, while they may involve aspects relevant to construction, do not emphasize the immediate operational knowledge and familiarity an operator needs for effective management once the plant begins running. Supervising costs, selecting the construction team, or ensuring aesthetic design are important tasks, but they do not provide the same level of operational insight that is critical for the future success of the facility.
