AK Water Operator study plan

AK Water Operator · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Treatment Processes and Unit Operations & Math, Hydraulics, and Calculations

  • Map the full treatment train from source to finished water and describe the purpose of each unit process

  • Explain coagulation, flocculation, sedimentation, and filtration using correct terminology for each

  • Solve basic dosage and flow conversion problems (mg/L, lb/day, MGD to gpm) without notes

  • Define key water quality parameters (turbidity, alkalinity, hardness, pH) and state their treatment significance

Your checkpoint

A one-page hand-drawn treatment train diagram with a written purpose statement for every unit process, plus 10 worked dosage/flow problems showing all steps

Week 2

Treatment Processes and Unit Operations & Math, Hydraulics, and Calculations

  • Describe filter operation, backwash sequencing, and the indicators that trigger backwash

  • Identify common filter problems (mudballs, breakthrough, air binding) and their corrective actions

  • Calculate filtration rate, backwash rate, and unit filter run volume with correct units

  • Explain how temperature, coagulant dose, and mixing energy affect floc formation

Your checkpoint

A filter operations summary sheet listing five filter problems, their causes, and corrective actions, plus 10 filtration-rate calculations graded against a key

Week 3

Distribution System Operations and Maintenance & Math, Hydraulics, and Calculations

  • Identify distribution system components (mains, valves, hydrants, storage, meters) and state the function of each

  • Explain the causes of and controls for nitrification, corrosion, and biofilm in distribution systems

  • Compute detention time, storage volume, and pressure/head relationships in distribution systems

  • Describe cross-connection control and backflow prevention device types

Your checkpoint

A distribution system walkthrough checklist covering valves, hydrants, storage, and cross-connection points, plus a completed set of 10 detention-time and pressure calculations

Week 4

Disinfection and Disinfection Byproducts & Laboratory Analysis and Process Monitoring

  • Differentiate free chlorine, combined chlorine, and total chlorine and state how each is measured

  • Explain CT concept and how contact time, pH, and temperature affect disinfection efficacy

  • Describe the four DBP groups (TTHM, HAA5, bromate, chlorite) and their precursor and control strategies

  • Perform chlorine dose, demand, and residual calculations and interpret a breakpoint chlorination curve

Your checkpoint

A disinfection and DBP reference card covering chlorine species, CT factors, and the four DBP groups, plus 10 completed chlorine dose/demand/residual problems

Week 5

Source Water and Water Quality & Disinfection and Disinfection Byproducts & Laboratory Analysis and Process Monitoring

  • Classify source water contaminants (microbial, inorganic, organic, radiological) and match each to its treatment approach

  • Explain source water protection concepts including wellhead protection and surface water intake considerations

  • Describe sampling procedures, chain of custody, and QA/QC practices for chlorine and turbidity

  • Interpret a set of lab results and flag values that exceed typical operational or regulatory limits

Your checkpoint

A source-to-treatment contaminant matching table (at least 12 contaminants) plus a written interpretation of a 10-result lab data set flagging exceedances

Week 6

Regulations, Reporting, and Public Health & Pumps, Motors, and Mechanical Equipment

  • Summarize the key requirements of the Surface Water Treatment Rules and the Total Coliform Rule

  • Identify required monitoring frequencies, reporting deadlines, and public notification tiers

  • Describe pump types (centrifugal, positive displacement) and match each to its typical application

  • Explain motor protection, lubrication, vibration, and preventive maintenance practices for pumps and motors

Your checkpoint

A regulation quick-reference sheet listing each major rule with its monitoring requirement and reporting deadline, plus a pump/motor preventive maintenance schedule

Week 7

Safety, Emergency Response, and Security & Pumps, Motors, and Mechanical Equipment & Distribution System Operations and Maintenance

  • Identify confined space, chlorine gas, and electrical hazards and state the required controls for each

  • Outline the response sequence for a main break, loss of pressure, and a boil water notice

  • Describe security measures for treatment facilities and distribution assets

  • Explain lockout/tagout and personal protective equipment selection for common water system tasks

Your checkpoint

A two-page emergency response outline covering main break, loss of pressure, and boil water notice scenarios, with the safety controls listed for each

Week 8

Source Water and Water Quality & Treatment Processes and Unit Operations & Distribution System Operations and Maintenance & Pumps, Motors, and Mechanical Equipment & Disinfection and Disinfection Byproducts & Laboratory Analysis and Process Monitoring & Regulations, Reporting, and Public Health & Safety, Emergency Response, and Security & Math, Hydraulics, and Calculations
