COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1. Operate all facilities in a potable water distribution system classified by the State of California as a Certified D1 Operator or Certified D2 Operator system.

2. Assess the physical condition of the D1 or D2 potable water distribution system, correctly diagnose system problems, and take effective corrective action to resolve those problems.

3. Recognize water quality problems in a potable water distribution system, identify the cause(s) of the problems and select the appropriate action to resolve the problem.

4. Generate and maintain all required records involved with the operation of a D1 or D2 potable water distribution system and submit the appropriate data to the State of California in a complete and timely manner.

 

Objectives:

At the conclusion of this course, the student should be able to:

2. Determine head loss in common piping configurations used in potable water distribution systems.

3. Identify and describe pipe materials, valves, and storage facilities used in potable water distribution systems.

4. Identify and specify appropriate pumps, instruments, and control systems.

5. Determine if the physical facilities in a potable water distribution system are operating correctly.

6. Calculate chlorine dosages required to disinfect new and existing wells, pumps, water mains, and storage facilities.

7. Identify and remove contaminants from a potable water distribution system.

8. Develop, conduct, and keep records for a potable water distribution system water quality monitoring program.

9. Conduct an effective flushing program.

10. Determine safety issues relative to a specific D1 or D2 potable water distribution system and conduct an effective safety program to prevent workplace injuries.
