Which term describes the interlocking network of water mains in a city’s distribution system?

• A. Grid or gridiron
• B. Looping network
• C. Primary mains
• D. Service connections

Answer: (A)

A grid or gridiron describes the interlocking network of water mains in a city’s distribution system. This layout forms a connected web across streets, creating multiple paths for water to flow to hydrants and services. The redundancy of a grid means water can be supplied from different directions and a section can be shut down for maintenance without cutting off supply to others, which is especially important for fire operations. It also reduces dead ends, which can hinder water movement and flushing. Primary mains are the larger pipes that feed zones, and service connections are the lines from the main to individual customers. A looping network is related, but the standard term used for the city-wide interconnection is grid or gridiron.
