How can you have a silo when the water table is a few feet below

...Simple. You find a material to line the outer walls of the silo to
prevent sandtrout from encysting the water. It helps keep the sandworm
population down to a bare minumum, and if you think twenty thumpers will
call a bunch of worms, just watch what happens when someone fires off an
SRB or two from Canaveral!

Surprisingly, urban explorers have not found as much water inside the
silo as one might expect. Certainly there is water at the lowest level,
but it's not like the silo is completely full of water. The engineers
must have done a good job making the thing relatively water tight. If
it had been used operationally, I'm sure an appropriately sized sump
pump would have sufficed to keep the silo dry.

Well, part of the problem isn't so much water intrusion as much as creating
a "raft". As long as you anchor the silo or somehow make it weigh enough,
it shouldn't float to the surface.
