HI Water/WW Operator study plan

Map every Water Treatment objective into a one-page outline you write yourself, grouping coagulation/flocculation, sedimentation, filtration, and disinfection

Define and calculate dosage, detention time, and flow conversions (MGD to gpm to cfs) until you can do each unaided

Explain jar-test procedure and how results drive coagulant dose adjustment, in your own words

Build a formula sheet with units for each treatment calculation you expect to face

Describe conventional filtration operation, backwash triggers, and filter-to-waste logic from memory

Compare chlorine, chloramine, ozone, and UV disinfection by dose, contact time, and byproduct concerns

Calculate CT (disinfectant concentration times contact time) and check it against a target you set

List the major drinking water contaminant categories and the treatment process each one targets

Diagram a distribution system from source to tap, labeling storage, pumps, valves, meters, and service lines

Compute head loss, pressure, and flow using the standard hydraulic relationships you list

Explain cross-connection control, backflow prevention devices, and why each device type is chosen

Describe disinfection residual maintenance and how to troubleshoot a low-residual complaint

Outline main break response from notification to restoration, including isolation and public notice steps

Identify pipe materials, joint types, and typical failure modes and match each to a repair method

Explain storage tank operations: turnover, level control, and water quality concerns in tanks

Practice locating valves and interpreting a distribution map scenario you write yourself

Map the wastewater treatment train from influent to effluent and solids handling, writing your own flow schematic

Define BOD, TSS, and permit limits and explain how each is measured and why it matters

Explain activated sludge process control: MLSS, SRT, F/M, and return sludge adjustments

Describe nitrification/denitrification and the conditions that cause each to fail

Explain sludge thickening, dewatering, and digestion options and when each is used

Describe disinfection and effluent monitoring requirements for wastewater discharge

Troubleshoot common upset conditions: bulking sludge, foaming, and poor settling, with corrective actions

Calculate pounds formula and loading conversions until you can do them without notes

Draw a collection system layout showing gravity mains, lift stations, force mains, and manholes

Explain infiltration and inflow, how each is detected, and how each is reduced

Describe sewer cleaning, inspection (CCTV), and rehabilitation methods and when each applies

Outline confined space entry and hydrogen sulfide safety requirements for collection work

Take a full-length self-written 100-question practice exam covering all four domains under timed conditions

Review every missed question and write the correct reasoning for each in your own words

Re-drill your weakest two domains using the quizzes you built in earlier weeks

Recite your formula sheet from memory and identify any gaps to review before test day
