OK Water/Wastewater Operator study plan

OK Water/Wastewater Operator · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Public Water Supply

  • Map the Public Water Supply domain into a one-page outline covering source water, treatment train, distribution, monitoring, and operator duties

  • Define and write out from memory the key terms: MCL, MCLG, TT, AL, CCR, SDWA, and primary versus secondary standards

  • Trace a surface-water treatment train (coagulation, flocculation, sedimentation, filtration, disinfection) and state the purpose and one failure symptom of each step

  • Build a 20-item flashcard set for water chemistry and treatment terminology and self-quiz until you score 18 of 20

Your checkpoint

One-page domain outline plus a 20-card flashcard set with a logged self-quiz score

Week 2

Public Water Supply

  • Calculate chlorine dose, demand, and residual from given values, and explain the difference between free and total chlorine

  • Explain CT concept and disinfection contact time in plain language, then work three practice problems

  • Describe turbidity, pH, and disinfectant residual as treatment barriers and state why each is monitored continuously

  • List the required CCR contents and draft a sample CCR summary for a small community system

Your checkpoint

A worked problem set of 10 calculations (dose, demand, residual, CT, detention time) with answers and one-paragraph explanations

Week 3

Wastewater & Stormwater

  • Diagram a conventional wastewater treatment train from influent to effluent and label the purpose of each unit process

  • Define BOD, TSS, ammonia, and fecal indicator bacteria and explain what each tells an operator about plant performance

  • Explain the activated sludge process including mixed liquor, return sludge, wasting, and sludge age

  • Describe stormwater basics: impervious cover effects, the difference between separate and combined systems, and common best management practices

Your checkpoint

A labeled process-flow diagram of a wastewater plant plus a one-page comparison table of BOD, TSS, ammonia, and indicator bacteria

Week 4

Public Water Supply & Wastewater & Stormwater

  • Solve 10 mixed practice problems spanning water and wastewater math (flow, loading, concentration, detention time, solids)

  • Compare drinking water and wastewater monitoring and reporting obligations side by side

  • Explain combined sewer overflow causes and controls and how wet-weather flow affects plant hydraulics

  • Write short answers to five scenario prompts such as a chlorine residual drop or a rising effluent TSS

Your checkpoint

A two-domain practice exam of 25 items with answer key and a score of at least 70 percent

Week 5

Construction Permitting

  • Outline the construction permitting sequence for a water or wastewater project from pre-application through approval to inspection and closeout

  • Identify the typical contents of a permit application package including plans, specifications, design report, and site information

  • Explain the roles of the owner, engineer, contractor, and permitting agency at each stage

  • Describe inspection and approval steps at key milestones such as pressure testing, disinfection, and final connection

Your checkpoint

A one-page permit process flowchart with responsible party named at each step

Week 6

Construction Permitting

  • List the common reasons permit applications are returned or delayed and state how to prevent each

  • Explain how design standards and specification requirements translate into construction inspection checkpoints

  • Work through two hypothetical projects and identify which permits and approvals are needed and in what order

  • Draft a short pre-construction checklist an operator would use before accepting a new main or plant upgrade

Your checkpoint

A permit-application checklist and a pre-construction acceptance checklist, each with at least 10 items

Week 7

Watershed Planning

  • Describe watershed delineation and explain how land use, soils, and slope influence source water quality

  • Identify the main sources of nonpoint pollution and match each to a management practice

  • Explain source water assessment and protection planning, including delineation of protection areas and contingency planning

  • Describe how watershed plans set measurable goals and how stakeholders and funding fit into implementation

Your checkpoint

A one-page watershed protection summary for a hypothetical community linking three pollution sources to three management practices

Week 8

Public Water Supply & Wastewater & Stormwater & Construction Permitting & Watershed Planning

  • Take a full-length 100-item timed practice exam across all four domains and record the score per domain

  • Review every missed item and write a one-line reason for each miss

  • Re-drill the two weakest domains with targeted flashcards and calculations

  • Assemble a one-page formula and reference sheet you can recall from memory

Your checkpoint

Timed practice exam results by domain plus a one-page formula sheet and a list of remaining weak areas

Milestones

Week 2: Score at least 80 percent on a self-made 20-item Public Water Supply quiz and complete all 10 water math problems correctly or with corrected work shown

Week 4: Score at least 70 percent on the 25-item two-domain practice exam and submit both the process diagram and comparison table

Week 6: Complete both permitting checklists and correctly order permits and approvals for both hypothetical projects

Week 8: Score at least 75 percent overall on the timed 100-item exam with no domain below 65 percent
