COURSE CONTENT

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

1. Compute and compare the variables in the flow equation Q=VA.

2. Explain, demonstrate, and convert between water pressure and height of

   water column.

3. Demonstrate, analyze, and estimate static pressure at any elevation

   from a water distribution system profile.

4. Define, demonstrate, analyze, and compare two ways of imparting kinetic

   energy to water.

5. Explain and compare two ways of dissipating kinetic energy from water.

6. Define, demonstrate, and differentiate primary, secondary, and tertiary

   wastewater treatment.

7. Compare and contrast aerobic and anaerobic wastewater treatment.

8. Describe, assess, and summarize aqueous ionization of chlorine,

   ammonia, and carbon dioxide.

9. Explain and evaluate the relationship between disinfection and

   coliform testing.

10. Describe, explain, demonstrate, and compare and measure volts, ohms,

    and amps.

11. Summarize Ohm's Law, identify the variables, and solve for each.

12. Describe and interpret electrical "ground".

13. Describe, demonstrate, and differentiate AC and DC.

14. Explain and evaluate induction and its use in transformers.

15. Describe, differentiate, and evaluate drinking water MCLs (maximum

    contaminant levels) for chemical impurities.

16. Describe, measure, and evaluate NPDES (National Pollution Discharge

    Elimination System) permit effluent limits for chemical pollutants.

Methods of Evaluation/Basis of Grade.

Writing: Assessment tools that demonstrate writing skill and/or require students to select, organize and explain ideas in writing.		Writing 0 - 0%
None
This is a degree applicable course but assessment tools based on writing are not included because problem solving assessments are more appropriate for this course.
Problem solving: Assessment tools, other than exams, that demonstrate competence in computational or non-computational problem solving skills.		Problem Solving 25 - 45%
Homework problems
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 0 - 0%
None
Exams: All forms of formal testing, other than skill performance exams.		Exams 40 - 60%
Multiple choice, True/false, Matching items, Completion
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 10 - 20%
