He is wrong and right. They should be connected to the Internet when they aren't 30 year old PLCs ripe for abuse. Until then, cut the data lines and do water monitoring the old way.

You're missing the point. Keeping things up to date and holding infrastructure to higher standards than consumer tech is not a bad idea.
Taking things offline can also work, but wouldn't the cost of that exceed making specialized things and maintaining them?
We got into this situation due to cost, not ignorance.
