I love my rain barrels. I have 4 barrels setup around the house. After many changes, I settled on this rain barrel design. It is well designed and very useful. There are many questionable designs out there. Learn from my mistakes and build your own rain barrel.
Here are the parts I use in my rain barrels. I get my barrels from a local barrel recycler. Other good places to find barrels are car washes, soda bottling plants and online classified websites. Make sure they are food grade barrels.
