NY Water/Wastewater Operator study plan

Map the full drinking water treatment train from source intake to finished-water storage, and label where coagulation, flocculation, sedimentation, filtration, and disinfection sit in that sequence.

Define each core water-quality parameter (turbidity, pH, alkalinity, hardness, residual disinfectant, CT) and state the operational range or target you would maintain for each.

Compute basic dosage and flow problems by hand, including chemical feed rate in lb/day from mg/L and MGD, and percent removal across a treatment step.

Sketch a simple distribution system layout and identify where storage tanks, booster pumps, valves, and dead-end mains create water-quality risk.

Explain how coagulation and flocculation are controlled, including jar testing, coagulant selection, and how pH and alkalinity shift the optimum dose.

Describe conventional and direct filtration operation, including filter loading rate, run time, headloss, and the turbidity triggers that require backwash.

Calculate CT and explain how contact time, disinfectant residual, pH, and temperature determine disinfection credit for chlorine, chloramine, and ozone.

Identify distribution-system sampling locations and explain how to respond to a low residual, a positive coliform, or a pressure loss.

Trace wastewater from household discharge through collection mains, lift stations, and the headworks of a treatment plant, naming the purpose of each structure.

Describe primary, secondary, and tertiary treatment, including the role of aeration, mixed liquor, return activated sludge, and waste sludge in the activated sludge process.

Calculate loading and process control values including detention time, solids retention time, food-to-microorganism ratio, and sludge volume index.

Explain the purpose and typical setpoints of disinfection and dechlorination before effluent discharge.

Explain how collection system capacity, infiltration and inflow, and sewer backups are diagnosed and corrected.

Describe lift station operation, including pump cycling, wet well level control, and the failure modes that cause sanitary sewer overflows.

Identify the causes and control measures for common activated sludge problems such as bulking, foaming, and pin floc.

Interpret a set of laboratory results (BOD, TSS, ammonia, pH, dissolved oxygen) and decide what operational adjustment each result would trigger.

Summarize the Safe Drinking Water Act framework, including the roles of EPA and the state primacy agency, and how a maximum contaminant level differs from a treatment technique.

List the major regulated contaminant groups and state the monitoring frequency and reporting obligation for each group you are likely to handle.

Explain the Total Coliform Rule and surface water treatment rules in operational terms, including sampling frequency, repeat sampling, and public notification triggers.

Describe the consumer confidence report requirement and what an operator must supply to the person who prepares it.

Explain how cross-connection control, backflow prevention, and coliform monitoring protect public health in the distribution system.

Outline the Clean Water Act permitting framework, including NPDES permit limits, effluent monitoring, and the difference between technology-based and water-quality-based limits.

Describe how a discharge monitoring report is completed and what triggers a permit exceedance, bypass, or upset notification.

Identify the safety hazards of confined spaces, chlorine gas, hydrogen sulfide, and electrical equipment, and state the control measure for each.

Explain the operator certification requirement, the chain of responsibility from operator to chief operator to primacy agency, and the recordkeeping obligations that follow.

Describe spill prevention and response, including how to contain a chemical release, who to notify, and what to document.

Outline biosolids handling and residual management requirements from generation through final use or disposal.

Apply lockout/tagout, confined space entry, and personal protective equipment procedures to a realistic maintenance scenario.

Integrate all four domains by working through full-length practice sets under timed conditions.

Diagnose weak areas from practice results and re-study only the missed concepts rather than rereading entire domains.

Rehearse calculation types until each one can be solved without reference notes.

Review the compliance calendar, permit sheet, and troubleshooting matrix you built earlier and confirm each entry is still accurate.
