On-site operator mandatory at which facility grades?

• A. Grade 1 & 2
• B. Grade 2 & 3
• C. Grade 3 & 4
• D. Grade 4 & 5

Answer: (C)

The important idea is that staffing requirements rise with the complexity and risk of the water distribution system. For facility grades three and four, an operator must be on site because these grades represent systems that are larger or more complex, where immediate, hands-on oversight is necessary to monitor controls, respond to alarms, manage disinfection and sampling, and keep operations compliant. This on-site presence helps ensure safety and reliability in real-time. Lower grades are simpler systems, where the operations can be supervised or managed with less need for a permanent on-site presence.
