COURSE CONTENT

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

1. Identify all the major components that make up a potable water distribution system, understand the purpose and operation of each, and be able to operate these components.

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

3. Identify the commonly used pipe materials used in potable water distribution systems and the advantages and disadvantages of each.

4. Identify the different types of valves used in a potable water distribution system, and understand the purpose and operation of each type.

5. Identify and describe the most commonly used types of storage facilities.

6. Specify the correct size centrifugal pump for common pumping

applications in a potable water distribution system.

7. Identify and specify the correct instrument or control system for the most common operational monitoring and control needs in a potable water distribution system.

8. Determine if the physical facilities in a potable water distribution

system are operating correctly.

9. Disinfect new and existing wells, pumps, mains, and storage

facilities; calculate chlorine dosages.

10. Identify types of contaminants that could get into a potable water

distribution system, identify and remove sources of contaminants in

distribution systems.

11. Develop and conduct a potable water distribution system water quality

monitoring program.

12. Accurately measure basic water quality parameters from distribution

system samples such as pH, temperature, chlorine residual.

13. Conduct an effective flushing program.

14. Develop a record keeping system for a potable water distribution

system and keep accurate records.

15. Determine safety issues relative to a specific D1 or D2 potable water

distribution system and conduct an effective safety program to prevent on

the job injuries.
