I like this creative daisy chain of 50
gallon barrels as a low budget solution for rain water collection in a
suburban setting. This is a picture I found on Flickr.
We've found these types of barrels used for around 8 bucks at some of
the local feed stores, which is most likely cheaper than buying a new
500 gallon container.
I guess the real question in a project like this is how much time and
additional materials will it take in comparison to the easy way?
