Which statement accurately reflects lift station alarm procedures?

• A. They require checking the wet well velocity
• B. They require testing BOD bottles
• C. They require checking the motor control center and power panel
• D. They require only visual inspection of the building exterior

Answer: (C)

Lift station alarm procedures focus on the electrical and control systems that run the pumps, because alarms are meant to detect faults in power or motor operation so the station can be shut down or protected before problems worsen. Checking the motor control center and power panel is essential since these components route power to the pumps and house protective devices; if a breaker has tripped, a contactor is malfunctioning, or the MCC isn’t signaling correctly, alarms may not function or pumps may fail to start when needed. Ensuring these panels and their circuits are in proper condition keeps the alarm system reliable and the station able to respond to high-level events.

Verifying wet well velocity isn’t part of standard alarm procedures; alarms are driven by level, pump status, and power conditions, not by flow velocity measurements. Testing BOD bottles belongs in a lab quality control context rather than lift station alarm operations. A purely visual exterior inspection doesn’t address the functional reliability of alarms, electrical panels, or control wiring, which are critical for timely alerts and safe operation.
