They had an interesting flood around here some years back. Mooks that ran a service went in to take out some 6 to 8 feet of water out of a cellar.

Well, it isn't as easy as that. When you have that kind of water then the water table around the building is also high and is pressing against the building with force. See Vector Analysis, Beginners Level, Chapter One.

The foot-pounds pressing against the walls on the outside cancel out with the foot-pounds inside. This leaves the wall with the intended vertical load and no horizontal load.

So if you pump out the water internally you have a horizontal load on the wall which was not part of the design.

Yes, the building caved in.

Freakin' Artesian Wells, can't trust 'em.
