Perhaps, but municipal water runs by gravity whereas your well pump doesn’t operate during a power failure.
They're off grid, and can be swapped out if the PV panels or immersion pumps fail.
Ideally you should be pumping into tanks in any case, for the buffer, and those tanks can be placed on a hill to gravity feed .. or pump with a motor.
Here's a typical setup, sans old windmill: https://youtu.be/iZAMm_S3GNQ?t=383
