Why You Should Consider Rain Barrels
Every time it rains, thousands of gallons of clean water flow right off your roof. Most of it goes straight down the drain or into the ground, causing erosion or foundation problems. But what if you could capture that free water and put it to good use? Trust me, I’m using my best TED Talk voice right now for such an introductory paragraph. I’m even wearing a digital tie!
Collecting rainwater is one of the smartest, most eco-friendly ways to take advantage of a resource that literally falls from the sky. It saves you money, conserves water, and protects your home at the same time. What more could you ask for? Best of all, it requires such a simple setup that you can totally do it yourself! These setups are known as rain barrels. They can store rain for later use in your garden, reduce runoff, and keep excess moisture away from your foundation.
What Are Rain Barrels?
So, what are ‘rain barrels’ exactly? A rain barrel is a container that collects and stores rainwater from your roof through your gutter downspouts. Instead of letting that water pool around your home—where it can seep into the soil and cause foundation movement—it’s stored safely for later use.

Most rain barrels are made of plastic, wood, or metal and include:
A screen or mesh lid (to keep out leaves and mosquitoes)
A spigot or faucet near the bottom
An overflow outlet or hose
Optional fittings to link multiple barrels together
You can also find pre-made rain barrels at home improvement stores, but today we will teach you how to make your own with a food-grade barrel and a few plumbing parts.
Materials and Tools Needed
Materials
Rain barrel (40–80 gallons is typical)
Flexible downspout elbow or diverter kit
Cinder blocks or a rain barrel stand
Mesh screen (if your barrel doesn’t include one)
Hose or watering can (for water use)
Optional: overflow hose, sealant, Teflon tape
Tools
Measuring tape
Level
Drill with hole saw bits (for spigot and overflow holes)
Utility knife or tin snips
Screwdriver or wrench
Step-by-Step Guide to Building Your Rain Barrel
1. Choose the Right Location
Pick a downspout that’s easy to access and close to where you’ll want to use the collected water (like near your garden or lawn). Ensure the ground is level and stable—water is heavy, and a full 50-gallon barrel weighs over 400 pounds.
2. Prepare a Level Base
Set your rain barrel on cinder blocks or a sturdy stand. Elevating the barrel gives you better water pressure and makes it easier to fit a watering can underneath the spigot.
3. Modify the Downspout
Measure about 8–12 inches above the top of your barrel, then cut the downspout using a hacksaw or tin snips. Attach a flexible downspout elbow or a rain barrel diverter kit, directing water straight into the barrel’s opening. Diverter kits are a great idea because they automatically reroute excess water back down the downspout when the barrel is full.
4. Attach the Spigot
If your barrel doesn’t already have one, drill a hole about 2–3 inches above the bottom, insert the spigot, and seal it with washers, nuts, and Teflon tape to prevent leaks.
5. Add the Overflow Outlet
Drill a second hole near the top of the barrel for an overflow hose. This ensures excess water drains safely away from your foundation when the barrel fills up.
6. Cover and Secure
Place a fine mesh screen or lid on top of the barrel to keep out debris and mosquitoes. Make sure everything is snug and stable.
7. Test It Out
Run water from a hose into your gutter or wait for the next rainstorm. Watch to make sure the flow goes smoothly into the barrel and that overflow water drains safely away from your home.
How to Use Collected Rainwater
Now that you have your water, what can you do with it? While this water isn’t treated and is not for drinking purposes, you can definitely use it to water your lawn or garden, wash cars, clean patios or outdoor furniture, or fill birdbaths and planters.
Maintenance Tips
Much like everything else, a rain barrel will also require maintenance, so remember to:
Empty and rinse it every few months to prevent algae buildup.
Clean your gutters and screens to maintain flow.
Disconnect or drain the barrel in freezing weather to avoid cracks.
Check the overflow to ensure water stays directed away from the foundation.
The Benefits of Rain Barrels
A rain barrel will prevent foundation damage by reducing pooling water around the base of your home. It protects your landscape from erosion and runoff. Plus, it provides free irrigation water and supports sustainability.
In areas like the DFW Metroplex, where soil movement and water restrictions can be common, a rain barrel is one of the easiest and smartest upgrades you can make.
So, why not take the plunge? Start capturing that rainwater today! It’s a simple step towards a more sustainable lifestyle and a healthier home.
