Along the oceanside - typically for a roadway . . .
Per hydrant, there should be a below-ground tank of considerable size (at least 10,000 gallons) that is fed by a combination of a pipe that runs in from the ocean -PLUS- a second underground tank (system) that is fed by rainwater.
The water-strainers at the ocean end of the pipe and inside the second undergrand tank, need to be maintained. The strainers might have replaceable "socks" that would be cleaned - thus, "changing socks" are intervals.
Along the roadway vector, there might be a series of "second underground" tanks that are piped together.
The second tank system being independent from the municipal "domestic" water system."
The cistern tank per hydrant (ie not the second tank), includes a float valve mechanism that shuts off the flow of water from the ocean until the water level drops enough - that means the second tank (rainwater system) flow is not enough.
Somewhere in the local government records or library files, we would probably find a history of where some contributors to such a project, tried again and again . . . but met resistance from socialist party purity.
There is an unfortunate, politically-correct (jobs-preservation outranks preservation) symmetry to the dockside USS Bonhomme Richard fire and the oceanside Lahaina fire.
You ‘splained it perfectly. :)
I’d better shut up now, or some Socialist Democrat will come up with the smart idea of draining our Great Lakes to fight fires THOUSANDS of miles away.
Seriously? Live by fresh water and a few food sources; Fish, wild game, tillable land. How hard is that to understand? Learn to bake bread, to grow tomatoes and green beans, to sew on a button or to sew up a wound on a person, a pet or livestock.
You know, when it ALL goes South, I’m gonna be Queen of the World! ;)
Nah, they’ll kill me FIRST because I, ‘know too much.’ But FIRST - they gotta catch me. ;)
