Building a rainwater collection system involves using a S-bend aluminum downspout to connect your gutter to a large barrel. There is usually a filter in the downspout to keep leaves and other debris out of the barrel, and there should be an overflow spout near the top of the barrel to prevent the downspout from backing up if the barrel is completely filled. That means the barrel needs to be on level, well-draining soil to keep the lost moisture away from your house. A spigot is put on the bottom of the barrel to retrieve the water.
