Tanks 2

It looks like there may be easier ways to crack this nut.  The tanks themselves are not in bad condition. They would probably be ok but there is always the worry of dirty water issues.  With new piping in place what else could be done.

Well, it turns out that there is another solution.  Use the tanks as they are (check they do not leak) and then feed the tank output through a water treatment solution.  There seem to be a lot of these on the market using different mix and match technology.  A relatively simple filtration system to remove solids followed by an inline UV system to kill off any bags would do the job.  And at a fraction of the cost!
