Utility Operations & Infrastructure Flashcards

What is the primary function of a SCADA system in utility operations?

Answer: Supervisory control and data acquisition

SCADA systems allow real-time monitoring and control of utility infrastructure, improving operational efficiency and response times.

Which component is most commonly used to regulate pressure in a water distribution system?

Answer: Pressure reducing valve

Pressure reducing valves (PRVs) maintain consistent water pressure, protecting infrastructure from damage due to pressure surges.

What is the purpose of backflow prevention devices in utility systems?

Answer: To prevent contamination from reverse flow

Backflow prevention devices ensure that contaminants do not enter the potable water supply due to pressure differences.

Which type of utility infrastructure typically requires cathodic protection?

Answer: Metal pipelines

Underground metal pipelines are susceptible to corrosion, and cathodic protection helps prevent this by applying a small electrical charge.

What does a water utility use a flow meter for?

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.

Which factor is most critical for determining the sizing of a utility pipeline?

Answer: Estimated flow rate

Flow rate directly impacts the required diameter of a pipeline to ensure consistent service delivery and avoid pressure drops.
