How to build a rain barrel

We have several rain barrels in use at our house. They are very similar to this design, except for the filler.

They are great for watering in the summertime. The main downside to a rain barrel is when you hook a hose up to it, the water pressure is pretty low. Evidently you can buy an electric pump but that kind of defeats the green notion.

We use the rain barrels to fill up a hand held water bucket, and I'll hook up the hose and run it out to certain garden plants like tomatoes and peppers, where a slow stream actually is of benefit.
