FL Water Operator study plan

FL Water Operator · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Water Treatment Processes

Sketch the conventional surface-water treatment train (source → coagulation → flocculation → sedimentation → filtration → disinfection → storage) and label the operating parameter controlled at each step
State the purpose, typical chemical or physical mechanism, and one common failure mode for each unit process in the train
Solve 15 dosage and flow-conversion problems (mg/L to lb/day, gpm to MGD, detention time, filter loading rate) showing unit cancellation
Define turbidity, alkalinity, pH, and coagulant demand and explain how each drives coagulant dose adjustment

One-page hand-drawn treatment train diagram with parameters annotated, plus a worked problem set scored at 80% or better

Week 2

Differentiate conventional, direct, and membrane filtration by raw-water quality limits, pretreatment requirements, and residual-handling needs
Diagnose three written filter-troubleshooting scenarios (short filter run, turbidity breakthrough, air binding) and prescribe corrective actions
Describe the layout, pipe materials, and appurtenances of the four distribution system configurations (branching, grid, looped, dead-end) and their flushing implications
Compute pipe volume, velocity, and pressure conversion (psi to feet of head) for distribution mains

Written troubleshooting log covering three filter scenarios with causes and corrections, plus a 10-problem hydraulics worksheet

Week 3

Explain how system pressure, elevated/ground storage, and head loss interact to maintain adequate pressure at the farthest customer
Identify cross-connection hazards and select the correct backflow prevention method (air gap, RPZ, double check, PVB) for given situations
Sequence a main-repair and disinfection procedure from shutdown through flushing, chlorination, sampling, and return to service
Calculate disinfectant residual decay and required booster dosing to hold a target residual at the system extremities

A one-page distribution system fact sheet pairing each backflow device with its application, plus a written main-repair/return-to-service checklist

Week 4

Classify pumps by type (centrifugal, positive displacement, submersible, vertical turbine) and match each to its typical Florida utility application
Read a pump curve and identify best efficiency point, shutoff head, and the effect of changing impeller diameter or speed
Diagnose cavitation, air binding, and worn-wear-ring symptoms from described noise, vibration, and performance data
Outline a preventive maintenance schedule ( lubrication, packing/seal inspection, vibration checks, valve exercising) with realistic intervals

Completed pump-curve interpretation worksheet, scoring 80% or better, with a written 90-day PM calendar for one pump station

Week 5

Troubleshoot motor failures using electrical readings (amps, voltage imbalance, insulation resistance) and describe correct lockout/tagout steps before repair
Explain the operating principle and maintenance needs of valves, meters, chemical feeders, and SCADA instrumentation
Calculate chlorine dose, demand, and residual, and explain the relationship among free chlorine, combined chlorine, and total chlorine
Compute CT value and determine whether a given disinfection condition meets the required inactivation for Giardia and viruses

A worked chlorine/CT problem set (10 items) with all calculations shown and a summary sheet of the three chlorine species

Week 6

Design a sampling routine that specifies site, frequency, container, preservation, holding time, and method for total coliform, nitrate, lead/copper, and disinfection byproducts
Distinguish regulatory significance of total coliform, fecal indicators, and E. coli results, and describe the required public notification response
Interpret lab results against secondary and primary standards and determine compliance status
Explain formation and control of disinfection byproducts (TTHM, HAA5) including precursor removal and operational tradeoffs

A one-page sampling matrix table covering at least six analytes, plus a written compliance determination for three sample lab reports

Week 7

Apply Florida DEP operator certification and reporting requirements, including which events must be reported and on what timeline
Identify the OSHA and Florida safety requirements for confined-space entry, chlorine handling, and lockout/tagout, and select the correct PPE for each task
Describe recordkeeping duties for daily operational logs, chemical usage, backflow testing, and consumer confidence reports
Outline emergency response procedures for a main break, a chlorine leak, and a boil-water notice

A completed regulatory and safety quick-reference card (two pages max) listing reports, deadlines, and required PPE by task

Week 8

Take two full-length timed practice exams and score each domain separately to expose weak areas
Re-teach the three lowest-scoring domain topics using your own notes without referring to the study guide
Review all calculation types (dose, flow, detention time, CT, head/pressure, filter rate) in one consolidated formula sheet
Build a final 24-hour pre-exam review sheet limited to items you previously missed

Two scored practice exams with a written error analysis and a one-page final formula and flashcard sheet

Week 2: Score 80%+ on a 25-question Domain 1 quiz and explain the treatment train aloud without notes

Week 4: Score 75%+ on a combined Domains 1-3 practice set of 40 questions

Week 6: Score 80%+ on a 30-question Domains 4-5 set and complete the sampling matrix without reference material

Week 8: Score 75%+ overall on two timed full-length practice exams, with no domain below 70%
