What is the principal underground pipe in a water distribution system called?

• A. Gate Valve
• B. Steamer Connection
• C. Water Main
• D. Cavitation

Answer: (C)

The principal underground pipe in a water distribution system is the water main—the large backbone that carries treated water from the treatment facility into the distribution network and out to neighborhoods. It forms the core of the system, with smaller mains and service connections branching off to supply individual properties. A gate valve is just a control device installed on pipes to shut off or regulate flow, not the main pipe itself. A steamer connection pertains to steam systems, not potable water distribution. Cavitation is a pump-related hydraulic phenomenon, not a pipe name.
