In a distribution system, which term describes a net of water mains that provides multiple paths for flow?

• A. Loop
• B. Network
• C. Grid
• D. Conduit

Answer: (C)

Think about how water can reach any customer from many directions rather than following one single path. A grid captures that idea—the mains are laid out in a lattice of interconnected lines with numerous junctions, so water can reach points through multiple routes. This multi-path arrangement provides redundancy and flexibility: if one line is shut down or needs maintenance, water can still flow through other paths, helping maintain pressure and service.

A loop describes a closed circuit, which is a useful feature within a grid but doesn’t by itself convey the broader, interwoven network of paths that a grid implies. A network is a general term for interconnected parts, but grid emphasizes the patterned, multi-path layout of water mains. Conduit simply refers to the pipe itself, not the system’s layout or its capacity for multiple flow paths.
