What maintenance strategy replaces or remanufactures equipment at fixed intervals regardless of condition?

• A. Preventative maintenance
• B. Predictive maintenance
• C. Corrective maintenance
• D. Reliability Centered Maintenance

Answer: (A)

Fixed-interval replacement is about doing maintenance or remanufacturing at set times or usage levels, no matter what the equipment currently looks like. That’s preventive maintenance in action—you schedule work in advance (for example, every 12 months or after a certain number of runs) to prevent failures before they happen. It helps keep critical sewer equipment—like pumps or valves—running reliably by reducing the chance of unexpected breakdowns, especially when condition monitoring isn’t practical or when failures carry high consequences. The trade-off is that you may replace parts that still have life left, or miss late-stage wear you don’t see until it’s too late if interval timing isn’t well chosen. In contrast, predictive maintenance relies on real-time condition data to trigger actions, corrective maintenance responds after a failure occurs, and Reliability Centered Maintenance is a broader approach that selects the best strategy based on risk and consequences.
