Course Type: Voc/Tech

This course has been developed using the ABC Water Treatment, Water Distribution, Wastewater Treatment, and Wastewater Collection Need-to-Know Criteria. The ABC Need-to-Know Criteria describe the core competencies covered on the ABC standardized exams used by the Iowa DNR Operator Certification Program for their Water Treatment, Water Distribution, and Wastewater Treatment certification exams and by the Iowa Water Environment Association Certification Program for their Wastewater Collection certification exams.

The ABC Need-to-Know Criteria covered by this course are:

  1. Evaluate Characteristics of Source Water
  2. Monitor, Evaluate, and Adjust Treatment Processes
  3. System Information/Components
  4. Laboratory Analyses
  5. Operate, Maintain, and Evaluate Equipment and Lift Stations
  6. Perform Security, Safety, and Administrative


  1. Assess general hydraulic principles
    1. Identify types of head and pressure
    2. Define head, pressure, velocity, and horsepower
    3. Measure head, pressure, velocity, and horsepower

  2. Explain hydrology
    1. Define the hydrologic cycle
    2. Identify the parts of the hydrologic cycle
  3. Outline biological science principles
    1. Define microbiology
    2. Identify the types of microbes important to water and wastewater, microbiological indicators, and water-borne pathogens 
  4. Describe general chemistry principles
    1. Define uses of the periodic chart
    2. Use the periodic chart to perform calculations
  5. List general chemical properties
  6. Explore physical science principles
    1. Identify the 3 states of matter
    2. Describe how these states of matter impact water and wastewater
  7. Describe principles of measurement
    1. Define units of measure
    2. Compare English and Metric Systems
    3. Perform accurate calculations using both the English and Metric Systems
  8. Describe general electrical principles
    1. Define electromotive force, resistance, conductance, power, and current
    2. Recognize the units of measurement for electromotive force, resistance, conductance, power, and current
    3. Calculate amps, volts, watts, and resistance
