Sample Answers:

• In my previous role, I encountered a malfunctioning centrifugal pump that was causing reduced water flow. I first assessed the situation and reviewed the pump's performance data. After ruling out issues with the power supply and control systems, I inspected the pump itself and discovered that the impeller was clogged with debris. I followed the manufacturer's guidelines to safely disassemble the pump, clean the impeller, and reassemble the unit. After testing the pump's performance, I confirmed that the issue was resolved, and the pump was operating at optimal levels.

• To ensure that pumping station equipment is operating within the manufacturer's recommended specifications, I follow a rigorous preventive maintenance plan. This includes regularly inspecting and servicing pumps, motors, valves, and other critical components according to the manufacturer's guidelines. I also monitor key performance indicators, such as flow rates, pressure readings, and vibration levels, to identify any deviations from normal operating conditions. If I notice any issues, I troubleshoot the problem and take appropriate corrective actions, such as adjusting settings, replacing worn parts, or escalating the issue to a higher level of support if needed.
