When up here in the "frost belt"...Actually it gets really cold, not 
just frost  we don't worry much about rust from accumulating water.  
Except for very unusual conditions water in tower legs ends up with the 
legs split, not rusted.as in warmer climates.  I've never had a problem 
with water accumulating or rust and that includes a number of towers 
using dirt bases.  But, having said that some installations leave the 
tower where the water table, or ground water level is high enough to 
cause problems. Also drainage away from the tower, or rather lack there 
of, can create some big problems with a thin rust line right at the top 
of the concrete. 

One important note for towers set in concrete is to have the bottom of 
the legs extending well below the frost line and of course into a good 
drainage bed.
