  1. Work through a scaffolded problem set progressing from simple percent-solution calculations (e.g., converting a bulk hypochlorite solution to available chlorine) to multi-step dosage problems (e.g., calculating the pounds per day of a chemical needed to dose a flow of X MGD to a target concentration of Y mg/L), with each step checked before the next is attempted.
  2. Use the chlorine dosage–demand–residual triangle (Dose = Demand + Residual) to solve a set of 12 applied scenarios representing typical Class I–II exam problems: given any two values, calculate the third; students discuss why residual monitoring matters for public health protection.
  3. Participate in a peer-teaching exercise: each student is assigned one calculation type (feed rate, dilution, Ct disinfection concept) and must explain the formula, walk through a sample problem on the whiteboard, and answer one question from classmates; instructor provides corrective feedback on accuracy and clarity.
Scientific calculators; operator math formula reference sheet; chlorine calculation problem sets; whiteboard and markers; AWWA Water Treatment: Principles and Practices of Water Supply Operations (current edition) Chapter on disinfection math (reference only); blank problem-solving templatesScore ≥75% on a 15-question timed chemical-math quiz; peer-teaching demonstration rated by instructor on a 3-point rubric: formula accuracy (must be correct), calculation steps (must be shown), and explanation clarity (must be understandable); any formula error in the demo triggers a redo.

  2. Complete a simulated shift log for a 24-hour operational period using a pre-formatted operator log template: students are given a narrative describing flow readings, chemical feed adjustments, equipment alarms, and a visitor entry, then must translate the narrative into concise, accurate log entries with correct units, times, and operator signature blocks—just as a licensed operator would be legally required to do.
  3. Practice completing a water-sample chain-of-custody form from a scenario: students record sample location codes, collection time, preservation method, and requested analyses, then review two intentionally erred forms submitted by peers and write a brief corrective memo explaining each documentation error and its regulatory consequence.

  1. In a computer lab, build a basic spreadsheet (using free or institutional software such as LibreOffice Calc or Microsoft Excel) that ingests one week of hypothetical daily flow, turbidity, and chlorine residual readings, calculates the weekly average and identifies any values exceeding a threshold, and produces a simple line graph—skills directly applicable to monthly operating report preparation.
  2. Use a CMMS simulation module (or a printed scenario representing a CMMS work-order screen) to create a new preventive-maintenance work order for a pump, assign priority, record labor and parts, and close the order with a completion note; students then run a simulated 'overdue work orders' report and explain what it tells the supervisor.
  3. Enter a set of hypothetical drinking water monitoring results into a simulated state safe drinking water online reporting portal interface (a mock web form structured like common state portals); students practice selecting the correct monitoring period, sample point, contaminant code, and result unit, and identify what happens if a result exceeds the maximum contaminant level—including automatic notification triggers.

7Career Readiness, Professional Conduct, and Licensing Pathways18theoryStudents will describe the employment landscape and career ladder for water and wastewater operators, articulate the Class I and Class II licensing requirements and exam domains in their state, and produce a professional resume and cover letter targeted to an entry-level operator position.
  1. Research their specific state's water operator and wastewater operator licensing structure using the state primacy agency or certifying board website: identify the application requirements for Class I and Class II in both disciplines (education, experience, exam), list the exam content domains published by the board, and present findings to the class in a five-minute structured talk—correcting any misconceptions about what Class I vs. Class II operators are legally permitted to do unsupervised.
  2. Engage in a panel discussion with two guest speakers: one currently licensed Class II water operator and one licensed wastewater operator, each employed locally; students prepare at least three questions in advance focusing on daily duties, how licensing affected their job eligibility and pay, and advice for exam preparation; students submit a written reflection connecting the panel to their own career plan.
  3. Draft a professional resume and targeted cover letter for a posted entry-level water or wastewater operator trainee position (real or simulated posting); the resume must include a skills section listing relevant safety credentials (OSHA 10, CPR), math competencies, and any certifications earned; students exchange drafts for peer review using an employer-perspective checklist, then submit a revised final version.
State licensing board website access; state operator exam candidate handbook or bulletin (current version); panel speaker coordination materials; entry-level job posting (real or simulated); resume and cover letter templates; peer-review checklist; professional communication rubricLicensing research presentation rated by instructor: all key Class I and II requirements accurately stated (any inaccurate legal claim about scope of practice = correction required before sign-off); written reflection ≥200 words showing specific connection between panel content and student career plan; resume and cover letter meet all items on employer-perspective checklist (resume must list OSHA 10 and CPR credentials and include no factual errors about the student's own background).

  2. Using process flow diagrams from prior coursework and state operator study manuals as references, sketch a preliminary process flow diagram for the scenario facility by hand, label each unit, and annotate with the key water quality parameter each unit is designed to address.
  3. Participate in a small-group technical review session where each student presents their scope-of-work document to two peers who use a structured checklist to identify gaps in regulatory identification, safety hazard listing, or process logic; revise the document based on written peer comments before submitting.
Scenario packet (instructor-developed, based on actual small-system or municipal facility), Site Assessment Worksheet template, blank process flow diagram paper and straightedge, state drinking water or wastewater operator study manual, EPA Small System Compliance Technology guides, colored pencils for PFD annotation, peer review checklistInstructor scores the submitted scope-of-work document and annotated PFD using a 20-point rubric: all unit processes correctly identified (5 pts), all major regulatory triggers listed with correct authority cited (5 pts), all OSHA-relevant hazards identified (5 pts), PFD is legible and logically sequenced (5 pts). Pass mark: 14/20 (70%).
2Operations Plan and Compliance Documentation54practiceThe student will produce a complete written operations plan for the assigned scenario that includes a process narrative, chemical feed and dosing calculations, a sampling and monitoring schedule aligned with permit requirements, daily log forms, and a regulatory compliance summary referencing applicable federal and state standards.
  1. Write a process narrative (minimum three pages) that describes, in operator-level language, how each unit process in the scenario facility functions, what parameters operators must monitor, what normal operating ranges are, and what the operator should do if a parameter goes out of range; the narrative must reference at least one state or EPA technical guidance document per major process unit.
  2. Complete a chemical feed calculation worksheet for at least two chemicals used in the scenario (for example, chlorine disinfection and pH adjustment, or coagulant and sludge conditioning chemical): given flow rate, target dose, and chemical purity, calculate feed rate in pounds per day and in mL/min for a liquid chemical metering pump, showing all unit conversions; verify calculations with the instructor before incorporating them into the plan.
  3. Design a sampling and monitoring schedule table that lists each required parameter, sampling location, minimum sampling frequency, analytical method reference (standard method number or EPA method number, left general if uncertain), reporting deadline, and the permit limit or action level; cross-reference this table against the regulatory compliance summary section of the operations plan to confirm every permit condition is addressed.
Word processor or technical writing software, engineering calculator, Chemical Feed Calculation Worksheet (instructor template), state operator study manual, EPA Guidance on Small Drinking Water System Compliance or comparable wastewater effluent guidelines, blank daily log form template, spreadsheet software for table construction, scenario permit document (simulated)Instructor evaluates the draft operations plan using a 40-point rubric: process narrative is technically accurate and complete (10 pts), chemical feed calculations are correct with units shown (10 pts), sampling schedule covers all permit-required parameters at correct frequency (10 pts), regulatory compliance summary cites correct authorities and maps each permit condition to an operational control (10 pts).

How the course runs. 4 blocks: Diagnostic Assessment and Exam Domain Orientation; Focused Domain Review: Treatment, Distribution, Collection, and Regulations; Operator Math and Calculation Intensive; Full Mock Certification Exams and Final Review.

What competent looks like. Correctly solve water and wastewater math problems—including flow rates, chemical dosing, detention time, unit conversions, and percent removal—at a level consistent with Class I–II exam expectations. Accurately recall and apply key concepts from all major exam domains: treatment processes, distribution and collection systems, pumping, laboratory procedures, sampling, and applicable regulations. Interpret process diagrams, operating data tables, and regulatory language as presented in exam item formats and select correct responses at or above the established passing score. Demonstrate effective time-management and test-taking strategies by completing a full-length timed mock exam within the allotted time while maintaining accuracy. Identify personal weak-domain areas through diagnostic scoring and self-direct focused review using study references such as state-approved operator study guides and AWWA/WEF operator manuals. Complete the exam registration process, including verifying eligibility documentation, application requirements, and the state licensing board's procedures.

#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Diagnostic Assessment and Exam Domain Orientation10practiceStudents complete a timed diagnostic practice test covering all major exam content domains and use scored results to build a personalized study plan that prioritizes low-scoring areas.
  1. Take a 100-question timed diagnostic practice exam that mirrors the format and domain weighting of the State Water Operator and State Wastewater Operator Class I–II exams; score it by domain and record results on a personal gap-analysis worksheet.
  2. Review the official exam content outlines published by the state licensing board (or a recognized body such as TREEO/ABC) side by side with the diagnostic score report to map each missed item to a specific domain (e.g., treatment processes, distribution, regulations, math).
  3. Complete the licensing board's exam application checklist as a classroom activity—identifying required work-experience documentation, application deadlines, exam fees, and acceptable forms of identification—so every student knows exactly what to submit before sitting the real exam.
100-question diagnostic practice exam (instructor-prepared or state-approved study guide bank), state licensing board exam content outline, personal gap-analysis worksheet, AWWA Water Operator Field Guide, WEF Wastewater Operator Field Guide, exam application checklist from the licensing board websiteCompleted and scored diagnostic with all items mapped to domains; completed application checklist with no missing fields. Pass mark: 100% completion of both documents; diagnostic score is used for planning, not grading.
2Focused Domain Review: Treatment, Distribution, Collection, and Regulations22theoryStudents recall and correctly explain the principles, operational procedures, and regulatory requirements for water treatment, distribution systems, wastewater treatment, collection systems, and relevant drinking water and wastewater regulations as tested on Class I–II exams.
  1. Rotate through six structured review stations (water treatment unit processes; disinfection and residuals; distribution system operation and maintenance; wastewater treatment unit processes; collection system operation; and regulations including Safe Drinking Water Act requirements and Clean Water Act permit basics), completing a 15-question practice quiz at each station and reviewing every wrong answer with the answer rationale before rotating.
  2. In groups of three, use process-diagram flashcards (instructor-prepared) showing unlabeled schematic drawings of a conventional water treatment plant and a secondary wastewater treatment plant; teams race to label all unit processes, identify the purpose of each step, and state one critical operational parameter—instructor corrects misconceptions immediately after each round.
  3. Complete a structured written-response activity in which each student selects their two lowest-scoring stations from the rotation and writes a one-page plain-language explanation of the key concept they missed, citing the correct page in the AWWA or WEF operator manual, then exchanges papers with a peer for accuracy review.
AWWA Water Treatment: Principles and Practices of Water Supply Operations (current edition), WEF Operation of Water Resource Recovery Facilities (current edition), state-approved operator study guides, process-diagram flashcards, six-station practice quiz sets, Safe Drinking Water Act and Clean Water Act summary handouts, whiteboard and markersStation quiz average of at least 70% correct across all six domains before moving to the next lesson; written explanation reviewed by peer and initialed by instructor as factually accurate. Students below 70% on any station complete a targeted re-read and retake an alternate 10-question quiz for that domain.
3Operator Math and Calculation Intensive18practiceStudents accurately set up and solve the full range of water and wastewater math problems appearing on Class I–II exams—including flow, volume, detention time, chemical dosing, percent removal, pump efficiency, and unit conversions—using dimensional analysis within allotted exam time limits.
  1. Work through a paced instructor-led session covering the ten most-tested calculation types: flow rate (Q = A × V), volume of tanks and basins, detention time, chemical feed rate and dosage, chlorine demand and residual, percent removal (BOD, TSS), weir overflow rate, surface overflow rate, pump efficiency, and unit conversions (MGD to GPM, cubic feet to gallons, etc.); for each type, the instructor models one problem using dimensional analysis, then students immediately solve two parallel problems independently and check against posted answers.
  2. Complete a 30-problem timed math sprint (45 minutes, calculator permitted, no formula sheet) drawn from exam-style items; after time is called, students grade their own work using the provided answer key with full solution steps, then categorize errors as 'setup error,' 'arithmetic error,' or 'unit conversion error' on a personal error-log sheet.
  3. In pairs, students create and exchange two original word problems each (one water, one wastewater) modeled on real exam question stems, solve each other's problems, and present solution steps to the class for peer critique—instructor intervenes to correct any flawed problem setups or calculations.
Scientific calculator (student-supplied), dimensional analysis reference card, 30-problem timed math sprint packet, error-log sheet, AWWA and WEF operator math chapters, whiteboard for worked examples, answer keys with full solution stepsTimed math sprint score of at least 70% correct (21 of 30 problems); error log completed for every missed item. Students below 70% meet individually with the instructor, rework missed problem types with guided practice, and complete an alternate 15-problem sprint before lesson 4 begins.
4Full Mock Certification Exams and Final Review18practiceStudents complete two full-length, timed mock certification exams under realistic conditions and use scored results to confirm readiness or identify any remaining gaps before sitting the official licensing exams.
  1. Sit Mock Exam 1 (Water Operator focus): a full-length timed practice exam mirroring the domain weighting and item style of the State Water Operator Class I–II exam, completed under strict exam conditions (no notes, timed, individual work, cell phones away); immediately after time is called, students score the exam by domain using the provided answer key and record results on a readiness tracker.
  2. Sit Mock Exam 2 (Wastewater Operator focus): same format and conditions as Mock Exam 1 but weighted toward wastewater treatment, collection systems, and relevant regulations consistent with the State Wastewater Operator Class I–II exam; score and record results on the same readiness tracker to compare both mock scores against the state's published passing score threshold.
  3. Participate in a 90-minute targeted debrief session: instructor reviews the ten most-missed items across both mock exams using a class-wide item-analysis tally, explains the correct rationale for each, and each student writes a final two-item personal action list ('Before I sit the real exam I will review __ because my mock score in that domain was __ %') and shares it verbally with the class as a commitment statement.
Mock Exam 1 packet (Water Operator, full-length, timed), Mock Exam 2 packet (Wastewater Operator, full-length, timed), answer keys with rationales, readiness tracker sheet, scientific calculator, exam-condition signage (no talking, phones off), item-analysis tally sheet for instructorScore of at least 70% on each mock exam (or the current state-published passing threshold, whichever is higher); completed readiness tracker with both domain-level scores recorded. Students below 70% on either mock receive a written remediation plan from the instructor specifying domains and resources for self-study before exam registration is finalized.
