Watched the video on the page demoing the falcon heavy concept. The real pictures don’t have the water tower at the launch site like the concept video. Is there some reason the water tower was in the demo design but not the real thing ... — maybe the water tower is mobile and only in place during an actual launch? Or is this closer to a case where somebody thought the water tower would look cool so they put it in the demo video ...?

That's a CGI mockup created when SpaceX' modifications to 39A weren't even complete. The FSS also looks markedly different.

However, the water tower is there, as you can see here: https://twitter.com/wsm1/status/953099809803485184.

The water tower is just further away, that's why you don't see it in the images. It was still there during their most recent launch from LC-39A: https://youtu.be/CNRTNxZSPhE?t=2m20s
