B. Designing utility distribution systems
C. Monitoring, controlling, and maintaining the safe and reliable operation
of utility systems
D. Selling utility services to customers
Rationale: The primary responsibility of a utility system operator is to
ensure the safe, efficient, and reliable operation of utility systems by
monitoring equipment, responding to alarms, and maintaining system
stability.
2. Which instrument is commonly used to measure pressure within a
utility piping system?
A. Ammeter
B. Pressure gauge
,C. Tachometer
D. Hydrometer
Rationale: A pressure gauge directly measures the pressure of gases or
liquids in pipelines and vessels, allowing operators to monitor safe
operating conditions.
3. A utility operator notices a rapid pressure drop in a water distribution
system. What should be the first action?
A. Increase pump speed immediately.
B. Investigate the cause while following emergency operating procedures.
C. Shut down the entire system without notification.
D. Ignore the pressure drop if customers have not complained.
Rationale: Operators should investigate the cause while following
established procedures to prevent equipment damage, contamination, or
service interruptions.
4. What is the primary purpose of preventive maintenance?
A. Eliminate all equipment replacement
B. Increase utility rates
C. Reduce staffing requirements

B. Regulate flow
C. Prevent reverse flow
D. Measure flow rate
Rationale: Check valves automatically prevent reverse flow, protecting
pumps, pipelines, and equipment from damage.
8. Which parameter is most important when monitoring the
performance of a centrifugal pump?
A. Paint color
B. Pump manufacturer's logo
C. Flow rate and discharge pressure
