Experience building a ferro-cement cistern?

Has anyone constructed a cistern from ferrocement and a rebar armature?  Like Art Ludwig's Water Storage book.  I need to catch and store a fair amount of rain water and it seems to me that a site made ferrocement cistern is a lot of work; but do-able.  I'm working on infrastructure projects on my property and thought I get to a prototype cistern this fall.  I wanted to check in and see what big errors I can avoid....  Wouldn't we all rather make new mistakes?   And, it seems to me that pneumatic hog ring pliers would make the armature work a lot easier but I have no experience with them.  Am I thinking about that the right way?

Following this with interest, Greg. We are in the process of setting up IBC totes for water capture, but any water here goes green very quickly.

Greg, ive done a 200l and a 7000l ferro cement water tanks and even though it can Be cheaper than other techniques, it takes a lot of time for one person to do it. Its something to Be build in group activities, that way i strongly recomend it but if not its better to buy something from an existing company.
Good luck.

The Ecoshell Construction Video gave me some ideas
