Hydrant History: Standardizing Wet-Barrel Hydrants

After its first major fire in 1851, a San Francisco foundry began casting wet-barrel hydrants. A century later, Greenberg’s collaboration with water districts all over California had forever united hydrant engineering with municipal water management. But that didn’t mean the water providers and customers could live happily ever after. First, we needed assurance that the products storing and purveying water were safe, and that they functioned as a cohesive system. In short, the water industry needed regulation.

Hydrant History: The California Type Hydrant

Until 1850, hydrant innovation focused on dry-barrel designs that worked well in the cold. But California’s climate called for different types of fire hydrants.

San Francisco was reeling from a destructive blaze in 1851. At that time, there were no fire insurance companies: what was lost in the fire was lost forever. The city didn’t even have underground water networks. A new series of projects topped the municipal agenda: digging wells, channeling water, and casting hydrants. They just needed the right manufacturer for the job: who would step up?

The Worlds First Fire Hydrants 2

Getting water out of the ground remained an unsolved problem in 1800, despite all the advances in underground infrastructure; firefighters had either to plunge buckets in the nearest cistern or dig down to perforate the wooden mains that conveyed water before metal pipes.

Before the invention of hydrants, the first brigade on scene tore up the ground until they reached the wooden water main, pierced it open and flooded the dugout around the puncture. From this makeshift pool the brigade filled buckets and attached hoses. After the fire, they closed the hole in the main with a plug, and it was these plugs that gave rise to the hydrant’s original name: fireplug.
