Exercise: Developing an I&M Plan

Scenario: You are responsible for overseeing the maintenance of a small water treatment plant. The plant uses a combination of filtration, chlorination, and UV disinfection processes.

Task: Create a basic I&M plan for the plant, outlining the following:

1. Inspection Schedule: Develop a monthly inspection schedule for each major component of the treatment process (filtration, chlorination, UV disinfection). Include what will be inspected and how often.
2. Preventive Maintenance Tasks: List the regular maintenance tasks for each component (e.g., filter cleaning, chlorine tank inspection, UV lamp replacement). Include the frequency of these tasks.
3. Corrective Action Plan: Outline steps to be taken in case of equipment failure or malfunction (e.g., emergency procedures, contacting a repair service).

Note: This is a simplified example. A real-world I&M plan would be more detailed and specific to the equipment and processes used.
