How to build a rain barrel system?

Using the steps below, you can create your own rain barrel system.

1. Secure a downspout area from your house and near the garden. Cut the downspout with a hacksaw in 2 places and at least 4” above the top of the barrel.

2. Direct the downspout into the rain barrel by connecting the downspout elbow and bracket using PVC cement or screws. Direct the downspout into the rain barrel. Use a 50-100 gal plastic rain barrel.

3. To raise the barrel, add some cement blocks, bricks, or any wooden platform underneath.

4. Create an inlet with a filter on the cover of the barrel to avoid unnecessary materials in the water.

5. Attach a sewer standpipe near the base of the rain barrel.

6. Connect a rubber plug to the sewer standpipe.

7. Attach a diverter kit, or hose to the spigot (optional).
