Which term refers to the main pipe that conveys water from the source to the distribution system?

• A. Water main
• B. Service line
• C. Lateral
• D. Branch line

Answer: (A)

The water main is the backbone of a water distribution system. It carries treated water from the source toward the distribution network and hydrants, typically with a larger diameter and located in streets. The service line runs from the main to a specific building, and a lateral or branch line describes smaller segments off the main that feed particular areas or fixtures. Because the question asks for the primary conduit that conveys water from the source into the distribution system, the term that fits best is water main.
