UMC Utility Operations & Infrastructure 1 — Questions and Answers
Question 1: What is the primary function of a SCADA system in utility operations?
- Customer billing automation
- Supervisory control and data acquisition (Correct answer)
- Water treatment chemical analysis
- Power factor correction
Correct answer: Supervisory control and data acquisition
SCADA systems allow real-time monitoring and control of utility infrastructure, improving operational efficiency and response times.
Question 2: Which component is most commonly used to regulate pressure in a water distribution system?
- Booster pump
- Flow meter
- Pressure reducing valve (Correct answer)
- Chlorinator
Correct answer: Pressure reducing valve
Pressure reducing valves (PRVs) maintain consistent water pressure, protecting infrastructure from damage due to pressure surges.
Question 3: What is the purpose of backflow prevention devices in utility systems?
- To increase system flow rate
- To prevent contamination from reverse flow (Correct answer)
- To detect leaks in pipelines
- To boost chlorine levels
Correct answer: To prevent contamination from reverse flow
Backflow prevention devices ensure that contaminants do not enter the potable water supply due to pressure differences.
Question 4: Which type of utility infrastructure typically requires cathodic protection?
- PVC sewer lines
- Concrete storm drains
- Metal pipelines (Correct answer)
- Fiber-optic conduits
Correct answer: Metal pipelines
Underground metal pipelines are susceptible to corrosion, and cathodic protection helps prevent this by applying a small electrical charge.
Question 5: What does a water utility use a flow meter for?
- To track water quality
- To measure chlorine levels
- To measure water usage and system performance (Correct answer)
- To filter sediment
Correct answer: To measure water usage and system performance
Flow meters measure the volume of water passing through a system, which is essential for monitoring usage and detecting leaks.
Question 6: Which factor is most critical for determining the sizing of a utility pipeline?
- Color of the pipe
- Manufacturer recommendation
- Estimated flow rate (Correct answer)
- Length of the pipe
Correct answer: Estimated flow rate
Flow rate directly impacts the required diameter of a pipeline to ensure consistent service delivery and avoid pressure drops.
