Hello and thanks for letting me on your forum. I have a few simple questions in which I would like your opinions on and as I come up with more, I hope you can give me some insight. I found a good deal on 55 galon plastic drums that I may possibly use for water collection. They are 12 bucks a piece and the owner tells me that laundry detergent was stored in them. Do you think they are good enough for water storage with a proper clean and rinse job? Or would or wouldn't you chance it?
