You really do have to bond the two of them.  The VERY best way is to dig a
trench all the way around the building and install a loop of wire, #8 at
least (although I use much larger wire after the time and money to dug a
trench.)  This wire connects the rods and the water system.  While a full
loop is best yo can simply run a wire to the building's service entrance
but I think code requires these wires to be "protected" by any of several

You have to connect the grounds because otherwire you have a problem where
indoors there are two different ground potentials.  The Earth is just that
way, there is or may be a voltage potential between two spots.  There WILL
be a difference during a lightening strike.
