What is the color of hydrants supplied by 6-inch to 8-inch water mains?

Hydrants supplied by 6-inch to 8-inch water mains are designated with a color code of yellow. This color coding is part of a system that indicates the flow capacity of the hydrant, which is an essential factor for firefighters when assessing water supplies at incidents. Yellow indicates a moderate flow rate, typically between 500 to 1,000 gallons per minute, making it suitable for many firefighting scenarios. Understanding this color coding helps ensure that firefighters can quickly and effectively identify the capabilities of available hydrants in their response area.

The other colors like blue, green, and red indicate different flow ranges. Blue usually signifies a hydrant with a high flow rate, green represents a lower flow from 250 to 500 gallons per minute, and red indicates a very low flow, under 250 gallons per minute. Each color serves a specific purpose, ensuring that firefighters can make informed decisions regarding water supply during an emergency.
