This first sketch is the Tipper Tie water tower. I guess Tipper Tie has it's own water tower because this one is right behind their building. Plus it has Tipper Tie written on it.

Tipper Tie operates a full scale aluminum wire mill here, which includes wire drawing, annealing, etching, spooling and coiling to customers' specifications. (I had to look all that up ;)

Apex has at least four water towers. There is another one right next to this one in downtown near the train station.
