In a water distribution grid, what component supplies individual hydrants and users?

The correct answer is that the distributor component supplies individual hydrants and users in a water distribution grid. The distributor is specifically designed to branch off and connect to various hydrants and consumers, allowing water to be efficiently delivered to those endpoints. This component plays a crucial role in ensuring that neighborhoods and different areas have access to necessary water supply, particularly for firefighting and residential needs.

In the context of water distribution, the main lines and feeder lines serve different functions. Main lines transport water from sources to feeder lines, while feeder lines carry water to the distributor. Therefore, while these components are essential for the overall infrastructure, it is the distributor that directly connects to individual hydrants and users, facilitating their immediate access to water.
