Thank you. None of what you outline is easy or dirt cheap, I do not have those materials, nor a way of scrounging them. I have about 8500 gallons of rain tanks presently storing water for emergencies such as fire or power failure (we have a well on grid power). Not trying to discount what I think are helpful suggestions, just that what you suggest is in no way practical for us here. I simply don't have the resources or personal energy for such a project as you suggest. Just trying to be honest here, not trying to imply it is a bad idea.
