A distribution system consists of a network of pipes, storage tanks, control valves and hydrants.

• A. Fire control system
• B. Water treatment plant
• C. Distribution system
• D. Municipal water main

Answer: (C)

The distribution system is the network that moves water from treatment sources to the places where it’s stored and used, including through storage tanks, control valves, pipes, and hydrants. Those components define how water is delivered through the service area and kept at the proper pressure for firefighting and daily use. The fire control system refers to building-level protection like sprinklers and alarms, not the wider network that transports water. A water treatment plant is where water is cleaned before it enters the system, not the network that distributes it. A municipal water main is a primary pipe within the distribution system, but the term “distribution system” covers the entire network, including mains, tanks, valves, and hydrants. So the correct term for the described network is the distribution system.
