Becoming a doctor requires more training than most other jobs. It usually takes at least 11 years to become a doctor: 4 years of college, 4 years of medical school, and 3 years working in a hospital. For some specialties, doctors may have to work in a hospital for up to 8 years before they are fully trained.
This requires large volumes of water - between 500 and 1000 gallons per minute - depending on the diameter of the water main. This is why you may see us âflushingâ fire hydrants and letting the water run down the street. This is a standard procedure and the water is dechlorinated to protect the environment.
These colors give us a reasonably accurate picture as to how the hydrant should perform. They are easy to recognize and as fire crews travel the streets performing their various duties, they see these hydrants and get a feel for where the problem areas exist well in advance of a fire alarm being called in.
