I agree with John - ferrocement would be MUCH better here. The only better 
one may be a wood stave tank (swells up tight when wet)...entirely renewable 
and no (unless you use power saws) energy use or GHG created.

Another option is a large plastic bag (like used in the food industry for 
making wine etc), but I find I can detect a "plastic" taste when I drink 
from plastic...

ciao,
Kelly
