The pillar hydrant, also sometimes referred to as the dry barrel hydrant, is one of the most visible signs of fire protection measures that can be employed by firefighters. They are placed in the streets for emergency purposes, and are utilized mostly if there is a fire in the immediate vicinity. The pillar hydrant is connected to the area?s water supply, which means that at any given time, the water supply can be utilized through the dry barrel hydrant. If a fire occurs in a place with a hydrant close by, firefighters can easily connect their hose lines to the dry barrel hydrant and use the water in the extinguishing process.
