Let take this to worst case and the tower has no way for the water to
exit. And on top of it you live in a place where it freezes. And as
K7LXC has pointed out when it freeze you are going to split the legs.
This is an old bottom drain swimming pool trick. Drill a small hole in
the leg 4 or 5 feet up and pour 100% automotive antifreeze in. Unless
you live at the "North pole" you will go though winter with no trouble.

That's what typically happens.
Drilling a weep hole in the leg doesn't do much good since the water
trapped in the leg below the weep hole and in the concrete can't escape
(unless you've put gravel in the bottom of the hole which everyone has
mentioned). When a freeze comes along, the water trapped in the leg will
freeze, expand and split the leg above the base. So a weep hole really
isn't
going to do you much good.
