Drilling water wells is hit and miss. They are usually pockets of water,
not a continuous body of water likening an underground major lake. Whether
they hold out during some minor drought periods depends on many factors. A
holding tank like a 1.5/2K gallon versions are a good idea for a number of
reasons, but adds substantial cost to the water supply.


1 gallon per minute is over 1400 gallons per day... thats more
than enough for normal household use on a DAILY basis. The problem
is that water USAGE isn't evenly distributed. The solution
for that is a low-volume pump and a big-ass storage tank.

If you're irrigating, either crops or lawn, then you
should check with local authorities about how much water
you're likely to need, but at that point, I'd be looking
at annual rainfall, because if you use more water than
falls, then eventually you're likely to run out.
