At which type of facility is a remote operator allowed to operate?

A remote operator is allowed to operate at any Grade 1 or Grade 2 facility because these facilities typically have simpler operational and safety requirements compared to higher-grade facilities. Grade 1 and Grade 2 facilities generally deal with more fundamental water distribution processes, which can be effectively managed remotely without the immediate presence of an operator on-site.

In contrast, higher-grade facilities such as Grade 3 and Grade 4 involve more complex systems or higher risks that necessitate on-site supervision or more skilled operators to manage potential issues effectively. Therefore, it's important that remote operations are primarily suited for the less complex Grade 1 and Grade 2 facilities. This allows operational efficiency while maintaining safety standards within the water distribution system.

Backup operators are valuable for ensuring continuity in operations, but they do not specifically define the capabilities of a remote operator in relation to facility grades. Thus, the stipulation focused on Grade levels is central to understanding where remote operations can be most effectively applied.
