Grounding circuits in barn

I am going to run 2 20 amp circuits to my barn which is 75' from the load center at the house. One will be a 240V circuit for my sprinkler pump and the other will be a 120v for lighting and a couple outlets.

I am planning on running conduit from the load center to the barn and will use #12 THHN. My question is what to do about grounding the sprinkler pump. It is connected to a 14' driven well via steel pipe. Should I connect the pump to the ground wire I run from the load center or does the well casing act as a ground?

I don't want to end up bonding the load center to the well casing with a 75' #12 wire.

Also since this is a steel pole building should I bond the ground to the barn itself?

I don't think you can run a 110v and 220v circuit to a separate structure without putting a subpanel out there (I forget the exact rule - isn't it something like 2 110v circuits is ok but any more and you have to install a panel?). Might be cheaper anyways to run 4 conductors to a panel in the barn, rather than the 6 you'd have to run as you have it planned. Plus if you want to add more circuits in the barn later, you won't have to pull more wire.

Under code you can not run two circuits to a detached building. To do what you are planning requires a sub panel to be installed in the barn,
