June 25, 2013 – Firefighters from Mill Creek Fire Company practicing a maxi-water drill evolution. This drill maximizes the amount of water flowing from a fire hydrant. In the event of a large structure fire, a fire engine can pump two 4” supply lines from the hydrant to the fire scene. In order for this process to work, the two 2.5” and the single 5” connections on the hydrant are used to deliver as much water to the fire engine’s pump. In return, the fire engine’s pump then pressurizes the water and delivers over 1,500 gallons of water a minute to the fire scene. In this scenario the two 4” hose lines fed a quint aerial ladder that was pumping a portable 500 gpm monitor unit, located on the ground, and its aerial ladder 1000 gpm waterway monitor nozzle. Firefighters spent a couple of hours running through the process and honing their skills to move large amounts of water for larger scale structure fires.
