I've extolled the virtues of an elevated tank delivering gravity
water for many years. Not everyone has enough elevation to make it
sensible. A tank on a wooden platform delivers very low pressure. It
takes 2.1 feet elevation to create one psi at the faucet or
showerhead. A wooden platform for a water tank must be very strong
and sit upon a good footing.
Regarding the compressed air pump, I always think of energy in and
energy out. What creates the compressed air? What is the source and
what is the cost? I suppose to evaluate the efficiency one would need
to compare some other pump cost per thousand gallons, say, and the
compressed air pump energy source the same.

I have been looking into rainwater collection. Rainwater tanks are usually
located near ground level or slightly above.
