Water treatment and storage

another one for the file: Scandinavian water technologies http://www.scan-water.com/home.php

They make portable water treatment, storage and distribution systems.  the one that caught my eye, giant water beds (they call them pillow tanks), for storing potable water, one model for stationary storage, another to be loaded on a flatbed truck.

I've been looking at the pool in the back yard, and thinking that would be a cheap way to have a cistern/water storage tank... similar system could be used for irrigation water as well.
