Which network provides water from source to consumer and includes distributor pipes serving hydrants and buildings?

• A. Grid Systems
• B. Distribution Systems
• C. PDP
• D. Safety

Answer: (B)

The network being described is the distribution system. It’s the part of the water supply that carries treated water from the treatment plant through transmission lines and into a web of distribution mains and distributor pipes. These distributor pipes branch out to serve hydrants and building service connections, delivering the water to both firefighters for incidents and everyday consumers at appropriate pressures. Think of it as the lower-level network that actually reaches the streets and buildings after water has been treated and moved into wider lines; hydrants are tied into this system so fire crews can access water quickly. The other terms don’t fit this role: grid systems isn’t a standard term for the water network delivering to street-level outlets, PDP isn’t a recognized descriptor for this portion of the system, and safety refers to precautions rather than the water delivery network itself.
