Reading all the posts about everyone cutting back, thought I'd share what I use to water my garden with. The pictures were two years ago and I've double each setup for a total of 10 barrels now. The water barrels from the metal roof are used for my veggie garden. The others for container plants.
I made them all myself, very easy to do and can give anyone step-by-step instructions if you're interested.
They are worth it, saves my water bill from doubling in the summer months.
