|how can i make a rain barrel from a garbage can?|
|Simply set the can next to the downspout and direct the downspout into the can. Use a cover with a small opening for the downspout to keep debris out of the can. You will either need to install a spigot at the bottom or plan to set a garden hose into the water so it will flow into the garden. The distance your barrel is from the garden isn't as important as the drop in elevation, so if you install a rain barrel, set it up so it is several feet above ground level and gravity will effectively move the water through the hose. I don't think it will come out of the end of the hose in a mad rush, but it should flow freely enough to make watering quick and efficient. If, after trying your new rain barrel, you want to increase the water pressure, you can either elevate the barrel more or set an immersible pond pump into the barrel. Some are solar powered, but they aren't cheap so I'd vote for elevating the barrel!
Good luck with your project!
