What flow range corresponds to green hydrants?

• A. 500-999 gpm
• B. Less than 500 gpm
• C. 1000-1499 gpm
• D. 1500 gpm

Answer: (C)

Hydrant color coding gives a quick visual cue of the approximate fire flow a hydrant can deliver. In this scheme, green hydrants indicate a flow range of 1000 to 1499 gallons per minute. This makes them a reliable source for moderate-to-high fire flows, useful for planning water supply and evaluating how well a system can support typical fire demands. Lower ranges (less than 1000 gpm) and the highest range (1500 gpm and above) correspond to the other color codes, not green. So the flow range that corresponds to green hydrants is 1000–1499 gpm.
