This document seems to apply to homes with their own water supply:

After a few hours of the circuit breakers being off, the old well
pumped for about two minutes before shutting down (which means
it's almost completely dry), but, luckily, the new well pumped
for 100 gallons before it shut down.

On the topic of the two tanks, one of which is for the fire
department hydrant, I have confirmed that mine is set up
to split horizontally across the two tanks (not by individual tank):

The incoming water from both wells merges into a single pipe
which enters the top of just one of the water tanks:

There is no other inlet, so, that water goes into both tanks:

Water exits at a single 4" pipe near the bottom of each tank:

From there, it goes to both the house & the wharf hydrant:

So, the *only* thing determining what water goes to the house
and what goes to the hydrant are the shut-off valve electronics:

Which is set to turn off the house at about 1/3 of the total water:

So, gravity feeds the hydrant; but the house is fed by the
booster pump, which turns off when 1/3 of the 4,500 gallons
is left. Interestingly, about 1 foot is about 500 gallons, so,
at the moment, I'm about 500 gallons from full:

Seems to me, if I "need" water, I can either pull it out of
the fire hydrant (which is below the house) or I can modify
the electronics (somehow) to just *not* turn off when 1/3
of the 4,550 gallons are left.
Does anyone know *how* that could be accomplished?
