    The hard part will be water lines for so much active water use. A sink and a few toilets is one thing but rigging an irrigation system that also has drainage for leaks or overflows requires space and lots of upfront renovation costs that will be paid back over a very long time. It’s a difficult financial proposition.

      You’re not running showers out whatever that needs fresh water and the goal would be to reuse that water over and over. You only need to get the water in there to begin with, then your pumps will move it around.

        The problem is a constant fight against gravity. You’ve still got to pump the water effectively to the top of the building every day. And there’s still the issue of getting sunlight to the plants.

        The question really becomes whether it’s more economical to just use traditional irrigation techniques upstream and ship the produce in vs converting a skyscraper into a very inefficient farm space.

          Vertical farming usually uses LED lighting, not direct sunlight. And I think the idea is that once the water is present on a given level it gets recirculated and reprocessed there, so it wouldn’t need much additional pumping.
