Want to harvest water at home for watering your home garden, containers, and other plants? Using just a few items, consider making a DIY rain barrel for harvesting water in your yard. It saves money and helps you to be more self sufficient.

What is a rain barrel?
A rain barrel is really any type of vessel or container that is used for harvesting or collecting rain water from a roof or other place. This can be any shape or size really, but you want it to be easy to access and use.

Rain barrels can be as basic as a large drum, like the one we have used, or be a connected system of containers for a larger harvesting system. The goal is to collect water and to be able to keep it on hand until you need to use it.
Materials for a DIY Rain Barrel
There aren’t many supplies needed to make a DIY rain barrel, so it really can be done by anyone. Here’s what you’ll need:
- Waterproof container of a good size (check facebook marketplace or local businesses that may use these large containers.)
- Drill with bit
- 3/4 Bulkhead fitting (comes with silicone ring as well)
- 3/4 brass faucet
- Plumbing tape
- Waterproof Caulk (I like Gorilla Glue caulk or try marine caulk)
Other items that are optional, but helpful:
- Easy to Use Diverter (if attaching to downspout)
- Rain Barrel stand (helps with water pressure if attaching a hose. Here are the plans my father-in-law used to build ours. This is a pretty heavy duty stand!
How to Build a Rain Barrel at Home
- Begin by gathering all of your supplies. Fit bit on end of drill and mark on your barrel the best place for the spigot.
- Make a hole with the drill.
- Use bulkhead fitting lined with caulk and attach to hole in barrel. Let dry.
- Wrap plumbing tape around the threads of the faucet that will attach to bulkhead. Attach the faucet.
- Test the seal by filling the barrel to just above the spigot to check for leaks around your bulkhead.
- If it leaks, use marine caulk around the bulkhead fitting and allow to dry. Test again.
- Place rain barrel on stand or in the location you’ve chosen for rain collection.
- Optional: if connecting a downspout to the rain barrel, follow instructions on the diverter for attaching and running a line to your barrel.
- Optional: If not using a diverter, consider creating a mesh screen for the rain barrel lid to screen out leaves or other matter that could potentially get inside.
Using Water in a Rain Barrel
For using the water in your rain barrel, you can either attach a hose and water plants/garden, or use it to fill a water can. There won’t be as much water pressure as a traditional spigot, but using a stand helps with this.
