Rainwater harvesting is one of the best ways to save money on water and become more self-sufficient. But if you’ve looked into rain barrel systems, you know how expensive they can be. A single rain barrel costs $80 to $120.
Fortunately, you can build a simple rainwater collection system using materials you can find at your local hardware store—all for less than $100. The key? Using a 32-gallon trash can as the main reservoir. I found this setup on the Youtube channel, Vibrant Deals.

Here’s how you can build your own rain barrel system on a budget:
What You’ll Need
- 32-gallon blue recycle trash can
- Brass spigot (quarter-turn type)
- Six 8″x8″ cinder blocks
- One 18″x18″x2″ cement paver
- Gutter drop outlet with a 2″x3″ extension
- Flexible gutter tubing
- Pool skimmer sock
- Utility knife
- Screws and clips for securing components
Step-by-Step Setup
- Build the Base: Create a stable, elevated platform using the six cinder blocks arranged in two layers, topped with the cement paver. This helps with water flow and makes it easy to use the spigot.
- Install the Spigot: Drill a hole near the bottom of the trash can and insert the brass spigot. Tighten it from the inside to ensure no leaks. This placement ensures you can drain as much water as possible.
- Cut the Lid: Use a utility knife to cut a 3″x2″ hole in the top of the lid. This will be your water inlet.
- Attach the Gutter System: Fit the gutter drop outlet over the opening you made in the lid. Secure it in place and wrap it with a pool skimmer sock to filter out debris and keep bugs out.
- Connect the Tubing: Attach a 2″x3″ flexible gutter extension to your downspout and direct it into the drop outlet. This is how rainwater flows into your barrel.
This DIY rainwater collections system is both affordable and customizable. You can always upgrade to a 50- or 55-gallon barrel later. For now, this 32-gallon setup is perfect for watering plants, washing hands, or minor outdoor tasks.
