Fire Hydrant
The street's most kicked, painted, and peed-on piece of critical infrastructure/Everyday Objects
A standard fire hydrant stands about 76 centimeters above ground (with another 60 cm below the surface), weighs around 230 kg, and delivers water at pressures around 550 kPa. Modern hydrants can flow over 5,000 liters per minute. They are painted specific colors to indicate flow capacity: blue for the highest, green, orange, and red for the lowest. Dogs have opinions about none of this.
