Three good uses for 30-gallon plastic drums are rain barrels, root cellars and storage containers. Reusing plastic drums can be a great way to help the environment.
A rain barrel is used to collect rain water that can be used in a garden during dry periods. The drum can be connected to a gutter and downspout to collect water. A spigot can be installed to the side of the drum to allow a flow of water through a water hose.
A root cellar is used to store vegetables and nuts underground. A plastic drum can be placed into a hole in the ground to store vegetables.
Plastic drums with clamp-on lids can be used as a storage container for almost anything. They can even be stacked on top of each other to take up less room.
