Collecting Rainwater

Reusing "gray water" (lightly used household water) and collecting rain water to water plants is something my mom has always done. This summer, I would like to create some kind of system to collect rain water outside to use to water my veggies. Last year, our water bill sky rocketed during the summer, which was to be expected. On Apartment Therapy, I found this picture and instructions on how they did it. It was pretty much what I had in mind. I still have lots of paint leftover from painting the shed, so I can paint the barrel the same color as the house.
