Thank you very much JRJ. I've been looking for a "reasonable" deal on larger plastics and 55 gallon drums, with decent shipping prices. Another option I've considered is Kaufman Container Co. They offer a decent price but have a $150 minimum order to the public. They have locations in many major cities so shipping usually is less of an issue.

I work for a place that sometimes throws away 35 and 55 gallon drums. They were all used to hold detergents or soaps. I've taken a few and turned them into rain barrels, though I never felt comfortable enough with cleaning them out to drink them them. I use the rain water for gardening and, in the event of a water shut-down, flushing the toilet and bathing. I plan to buy a 55 gallon drum for my drinking water with smaller 5 gallon containers for distribution.

What is your system like or what will it be?
Thanks again.
Michael
