What color indicates hydrants supplied by water mains greater than 16 inches?

Hydrants that are supplied by water mains greater than 16 inches are indicated by the color blue. This color coding is part of a standardized system used by fire departments to quickly assess water availability during emergencies.

Using blue for hydrants connected to larger water mains signals a high flow capacity, which is crucial for firefighting operations. Understanding this color code allows firefighters to make swift and informed decisions on where to source water, ultimately enhancing their efficiency in managing fires. The designation of blue for larger mains helps firefighters quickly recognize which hydrants can deliver a strong and reliable water supply when they need it most.
