Well, I received a few emails at asgreenasyoucanbe.com requesting a Rain Barrel how-to so here it is.
I have to admit that I was a little nervous to start this because I thought it might not work, or be leaky, but it was simple and doesn’t leak a bit.
The first step is to acquire a barrel, preferably a plastic one. There are several sources you can get these for very cheap and sometimes even free. Our local soft drink bottler sells them for $5, but I got mine free from a friend who works at an industrial plant. You have to be wary about what it was used for. Mine was used for some kind of cleaner, I might not drink out of it but I think its okay for plants. The barrel I got was bright screaming blue (ugg) so I got some tan spray paint specifically for painting plastic (low VOC of course) and gave it a good coat so it doesn’t stick out like a sore thumb. Then, off to the home center!
At the home center I picked up a brass spigot that was threaded on both ends and a brass garden hose female to female adapter. These were both the same size threads. I also picked up one of those flexible plastic downspout extenders.


I drilled two 1 inch holes in the sides of the barrel. One at the top and one at the bottom. When drilling these holes, try to keep in mind the bottom hole is where the water comes out and the top hole should be directed to where you want the overflow to go. Hopefully the pictures will explain this better.
With the 1″ holes drilled, I threaded the spigot right into the hole. I was tight but the threads were tapered a bit so they cut right into the plastic and made a water tight seal. Same thing for the F to F adapter, just thread it in and be done with it. You may need a wrench, because it was pretty tough to screw it in all the way. I planned on adding some silicone sealant but it wasn’t necessary, that sucker is tight!
Next you have to cut a hole in the top large enough for the flexible downspout extender to fit in. I used a jigsaw, but you could use a hacksaw blade or a circular series of drilled holes. This doesn’t have to be exact, but the tighter you get it the less chance you’ll have of foreign material getting in there, like leaves or sticks that can clog up the spigot.
Now you have to give the barrel a nice stable, level place to sit, next to your downspout. I used a couple of 6×6 cut offs that I had lying around to raise the barrel up a bit so I can get a watering can under the spigot. In hindsight, I would have raised it up a but more, maybe a foot off the ground. It is important to dig the ground level under the barrel supports because a 40 gallon barrel full of water will weigh over 350 pounds and you don’t want it sliding off! You can use cinder blocks to raise it as high as you’d like. They are very cheap and easy to come by.
Place the barrel where you want it to go and put one end of the flexible downspout extender into the hole in the top of the barrel. Now stretch the other end over to the downspout and mark a place on the downspout to cut. You can easily cut it in place with a hacksaw. Remove the lower piece of downspout and hook up your flexible downspout, I put a little screw through the plastic to secure it to the metal.
Make sure you close the spigot and wait for the rain! You can hook up a length of hose to the overflow and direct it where ever you want. You could even direct the overflow to another rain barrel and have a series of them. When the first one fills up, it will start filling up the second. Pretty cool, just make sure you have spigots in them or you won’t be able to get the water out.
There you have it, this is easily done in an afternoon. All you need now is a decent rainstorm and it will fill up very quickly. Now it wont run a lawn sprinkler but I use a soaker hose or sometimes I just squirt the grass. We also fill up a watering can when ever the garden needs a drink.
I hope this helps you on your journey to be as green as you can be.
