He's lucky it worked. I was involved with a wildfire on Long Island back in 95, most of the Hamptons were burning. One if the biggest issues we had was the fact that all the fire hydrants were empty. The whole system had zero water pressure. They ended up trucking water in in tankers.
We learned the hydrants were dry when we hooked up to one and opened up the deck gun. The deck gun puts out about 1000gpm and we had a 500 gallon tank on the pumper. 30 seconds of water and it shut off.
before the Black Saturday bushfires in Victoria Australia, one homeowner, put piping with sprinklers all around his house, his neighbours said he was an idiot. After the fires, ALL his neighbours asked him to help install the same system on their newly rebuilt homes as his was the only one left standing

Take note of the pond to the left. It likely feeds the sprinkler system.
