  • Step 1: In the first step, take the barrel and clean it using water and soap, or a cleaner. This is done to ensure that there is nothing contagious and poisonous in the barrel, that may spoil the water that accumulates.
  • Step 2: The actual process of building a rain barrel starts in this step. First, take the faucet and place it on the position where you want it to be located. Trace a light outline around the faucet on the barrel, with the help of a chalk or a marker pen.
  • Step 3: Drill a hole within the outline that you have traced. Ensure that the hole does not become too big. After you have made the hole, paste the large-sized washers on the inside and also on the outside the barrel, so that the hole becomes, uniform.
  • Step 4: Tape the threads of the faucet and then insert it in the hole, and tighten the washers if you want. Another very good option to make the faucet a hundred percent waterproof, is to tape the hole from all the sides. Using gum along with tape also helps.
  • Step 5: In this step, place the rain barrel below the rain gutter. You might also need to modify or install the rain gutter according to the barrel. If the hole that is present on top of the gutter is small, then enlarge it by using a hacksaw.
