You do not need water filtration, sewer treatment and HVAC on fully automated ship - you can eliminate a lot of stuff that supports humans.

Good point, which seemed to completely escape me. Though many ships still would need auxiliary systems such as non-propulsion power, hydraulics, cargo cooling, inert gas systems, fresh cooling water, etc etc. Point is, it'll still be an immense system that is not so easy to fully and reliably automate.

Not to detract from your general point, but fresh water is used for more than just human consumption.
