I wanted to share instructions on how to build a "drain barrel" for those of you who may not have gutters on your house. This project is most useful for those of us who have a clearly-defined gouge in our wood chips where the water pours off the roof.
Purchase three cedar decking boards and screw them together in the shape of a trough. Seal all joined edges with a clear silicone caulk.
Obtain containers in which the capture the rainwater; it would be best to find containers with about a 2" opening.
Line up the containers and measure the distance between the center of the containers' openings. Leave about 1/2" per container for expansion. Measure the diameter of the container's opening and use a hole saw (attached to the drill) to make holes in the trough.
Purchase a 10' length of PVC pipe. It should be slightly less in diameter than your hole. Count the number of holes and divide evenly. Cut the PVC into equal lengths. Purchase a narrowing PVC conduit to glue to the top of your pipes. Drill two holes in the widest part of the conduit and use a miter saw to remove the material between the holes. This will make a slit to help drain the water into the pipe and ultimately into your container.
Construct some simple "feet" to attach to the ends of the trough. If you drill a hole in the middle of the end of the trough, you will be able to swivel the trough up-side-down on the lag bolt to prevent snow from weighing the trough down during the winter. Dig a hole on both ends for the "feet", level the trough, and add concrete to prevent the structure from moving during a hard rain.
