I am trying to find unbiased advice prior to dealing directly with the well driller.

Location is South Central Texas.
Well will be about 360'.
The water will be used for my home, water livestock, and a big garden.
Ideally, I would like to have a raised water tank that I could use to irrigate a 5 acre garden with gravity. Is this even feasible? Note: the stored water tank does not have to irrigate all 5 acres at a time. I can rotate that.

What is a good diameter/gpm for such a well?

Best Regards,
