We're doing something similar (see the Homestead in NE Georgia
thread), in that we're building a water tower on our
land. Our pumps include a grid powered A/C submersible pump (although we have no grid tie on the property yet) and a Simple Pump (to which we will be adding the gear motor and a
solar set-up). Both will fill the IBC totes in the water tower, and the water will be distributed from there to the rest of the property by either gravity flow (when we have power) or a jet pump (when we don't). The main thing about getting the water into the tower, as far as I've been told, is to use one or more check valves in the supply line.
