If the water is uphill of where it's needed? Sure, and we've already done that. If the water is net uphill of where it's needed? Maybe, but requires enormous energy inputs, and infra to recapture on the downhill side, and has corresponding energy losses. If the water is net downhill of where it's needed? We almost certainly cannot, not without or building massive (hopefully nuclear/solar) energy infra.

Moving water is far, far more difficult than any other type of infrastructure we build.
