IThis connection has no pressure, you can remove the cap and you'd get noting, but the FD can connect to this and draw water from the pond to supply the firefighting efforts, either by running a 4" or larger line to the fire scene is it's close or by filling a tanker shuttle, FD water trucks that take the water to the scene and transfer it to the attack apparatus.

Exactly Dave.
The pipe with a cap on it that y'all see by your pond are called drafting stations;
the pumper hooks up a hard suction hose to this pipe and draws a suction, or 'draft' to pull the water out of the pond.
The engine that gets positioned on the draft cannot leave;
they are there to hold the draft and supply either:
1. a tanker, that will shuttle the water to the fire, where it is dumped into a manmade 'pool' and then drafted from the pool and applied to the fire.
or
2. the firefighters can hook large diameter hose to the draft pumper, and lay up to 1000 feet in the road way, thus creating an above ground water main for fire supression water to pass through. At or before the 1000 foot mark, another pumper must be placed if the distance is more than 1000 feet from the water source, and the fire.
It's a long lengthy process, that NH firefighters are tops at.
I'm a urban Chief. Here in NJ, we have hydrants every 165 feet, and pumpers that pump 200 Gallons per minute. water supply is nary an issue, and in my municipality, I have 3 2000gpm pumpers and a ladder truck with a 2000gpm pump at my disposal for fire attack.
At my madison home however, water supply for my home is about an 1/8th of a mile from the house, and the Madison FD would have to draft as I have described.
When I applied for homeowners insurance, I merely explained that there are no hydrants, and that the FD drafted, they understood. The difference between the NH insurance and the NJ insurance is minimal, believe it or not.
I have priced out retro-fitting a sprinkler system into the NH house, but it is costly; what with the price of another well, fire pump, and all the piping for the runs and rises.
In NJ, there is a big push for residential sprinklers to be installed during construction. It's win-win....great for the fire service, and also great for the homeowner.
