How to build a rain barrel for collecting rainwater

SAFETY FIRST: Ask an adult to help with tools you haven't used before.

Conserve water by collecting rainwater and using it for your garden or lawn.

WHAT YOU’LL NEED

  • Recycled food barrel (try checking with large restaurants or food distributors)
  • 2 to 4 concrete blocks (to allow room for a bucket to fit under the spigot)
  • 3/4-inch hose spigot
  • Drill
  • Saber saw
  • 3/4 x 1-1/4-inch threaded pipe nipple (used as overflow connector)
  • Window screen
  • PVC cement

WHAT YOU’LL DO

1. Wash out the barrel with a solution of 1/8-cup bleach and 5 gallons of water.

2. Drill a 15/16-inch hole a few inches from the bottom of the barrel. Thread the spigot halfway into the barrel, apply PVC cement onto the threads and continue screwing it in until snug.

3. Using the same procedure as the spigot, install the 3/4-inch overflow connector a few inches from the top of the barrel.

4. Choose a good spot for the rain barrel. It needs to be close to a rain downspout and a short distance from your plants and gardens.

5. Raise the barrel off the ground by placing it on concrete blocks. Reconfigure the downspout so it empties directly into the barrel. Use the screen to cover the open hole in the barrel to prevent insects or debris from getting in.

6. If you’ve installed an overflow, you can attach a hose and direct the water to another part of your yard.

      You can also contact a local car wash owner, they get soap and water treatment in large blue barrels. Most of these barrels are not the lidded style though. But that works out fine for a water barrel. Just clean it well I recomend letting watter sit in it for several days after a good clean then dumping it. (sometimes the soaps and treatment leech into the plastic).

  9. I bet lowes as some barrels cause after all lowes knows

    I would love to conserve water, but this is a lot tougher than it sounds. Be careful on this one… it’s super tricky!
