Prevent and respond to blockages
Recognize grease, roots, debris, structural defects, and capacity problems; prioritize public-health and overflow response.
Operator study track
Wastewater Collection Systems
Gravity sewers, lift stations, force mains, cleaning, inspection, inflow and infiltration, overflows, confined spaces, and records.
Use this page as a study checklist.
For your actual exam, open the current state candidate handbook or need-to-know criteria. This guide teaches operating reasoning; it does not claim to reproduce a protected exam.
Operate lift stations safely
Understand pumps, controls, alarms, wet wells, redundancy, backup power, and confined-space boundaries.
Separate I&I sources
Connect rainfall or groundwater patterns to inflow, infiltration, inspection, smoke testing, CCTV, and rehabilitation.
Document the system
Use maps, work orders, cleaning history, inspection video, overflow records, and asset condition to plan work.
A better 45-minute study block
- Read one concept and write the operating purpose in your own words.
- Write the measurement, alarm, or observation that would show the process is drifting.
- Write the safest first response and what must be verified before changing the process.
- Take 10 targeted questions and review every explanation, including correct answers.
- Save the weak topic in your notes and repeat it with operator math where applicable.
