It’s difficult but not impossible. Space stations have advanced the techniques for reclaiming water from waste. If the food was sent in a dehydrated state the mass would be greatly reduced. As long as the water is efficiently recycled the range is possible.
The whole thing was caused by the city cheaping out on mineral additives to the water that kept lead from leaching out of the pipes. To then turn it around and try to blame state officials is the height of hypocrisy. And par for the course for Michigan Dems. It’s crap like this that has me looking at other states to live in.
