Aaron makes rain barrels out of recycled plastic, and runs an informative web site about rain water harvesting.
The 58 gallon rain barrels are made out of thick food-grade plastic, and can withstand both hot and cold temperatures. The barrels connect directly to the downspout of your rain gutter.
They are also paintable (withÂ Krylon Fusion) for those who want to match the harvesting tank to the color of their homes.
They are available for $125 which includes shipping.
