I looked at the column as something that could be scaled down to a DIYer size.
If you could use 20 foot pipes with a much smaller OD, (4"?) and connect a bunch of them parallel,
they might be useful in high water-table areas..
Like my backyard!

Edit:
I wonder what would cost more, digging slinky ditches 8 or 10 feet deep? Or drilling 15 or 20 holes.. 10"x20' ??
In the end, the ditches would likely be cheaper.
Plus, the added cost of building the 20 foot tubes wouldn't be worthwhile..
