If hydrants are coded Red, Orange, Green, Light Blue, which color represents the greatest capacity?

• A. Red
• B. Orange
• C. Green
• D. Light Blue

Answer: (D)

Hydrant color coding is a quick reference for how much water a hydrant can typically deliver, measured in gallons per minute. Red signals the smallest flow, Orange a bit higher, Green even more, and Light Blue indicates the greatest capacity. So, Light Blue hydrants can supply the most water, making them the best choice when you need the maximum available flow. This helps you plan hose layouts and pump settings in the field to meet target water demands efficiently.
