Sorry for the ridiculous question in advance...

Sorry for the ridiculous question in advance, but I have virtually no knowledge of plumbing and probably everyone on this forum knows the answer. From what I understand, commercial office buildings with large open floor plans tend to have all of their plumbing running vertically from only a limited number of locations on each floor. That differs greatly from residential buildings that have vertical plumbing running through each unit. So the hypothetical scenario is this:

Imagine you had a large open office building floor plan. And you placed a number of modular bathrooms into the center of the empty room, could you hypothetically connect those units to make them functional WITHOUT breaking through the floor or ceiling? Meaning, could you run all of the piping horizontally until you reach a connection point? (Forget what it would look like because it would obviously be just a bunch of pipes laying across the floor) but is it possible? I assume that to get the pipes to circulate you would need suction but are their pumps that could easily make it work? I'm attaching an image to give a better idea of the scenario. I hope im not being too much of a bother for asking... and thanks for even reading this far if you have . THANKS!
