Then I learned how things are really done.

As far as remote access goes, yes, they could technically provide access from afar with a dedicated line of some sort, but the goal is convenience, not just remoteness, so we should expect such systems to find themselves attached to the wider Net. We want to be able to administer the system from our iPhones, right?

From what I’ve read, the pumps are not usually backed up with generators (which would have to be pretty large given the high horsepowers required for pumping.)

Re point #3, there are ways to provide remote access to a SCADA system without involving the Internet, via a private line or a switching technology such as MPLS, readily available from phone companies.
