Rain barrels capture roof runoff effectively when positioned near downspouts with proper overflow systems. If you are looking for the best rain barrels to save water and lower your utility bills, you have come to the right place. This guide will help you choose the right barrel, set it up, and maintain it without any hassle. We cover everything from material options to installation tips, so you can start collecting rainwater today.
Rainwater harvesting is simple and eco-friendly. A good barrel can store hundreds of gallons over a season. But not all barrels are created equal. Some leak, some attract mosquitoes, and some are just too small. Let’s find the one that fits your home and garden.
Why You Need The Best Rain Barrels
Collecting rainwater reduces your water bill and helps your plants thrive. Rainwater is free of chlorine and other chemicals found in tap water. It is perfect for watering flowers, vegetables, and lawns. Plus, using a barrel reduces stormwater runoff, which helps prevent erosion and flooding in your area.
Many cities even offer rebates for installing rain barrels. Check with your local water authority to see if you qualify. A quality barrel pays for itself within a year or two, especially if you have a large garden.
Key Benefits Of Rain Barrels
- Lower water bills during dry months
- Healthier plants with natural rainwater
- Reduced strain on municipal water systems
- Less runoff and erosion around your home
- Simple DIY installation with basic tools
Best Rain Barrels
Now let’s dive into the top options on the market. The best rain barrels combine durability, capacity, and ease of use. We have tested and reviewed several models to help you make an informed choice. Below are our top picks, each with its own strengths.
1. Good Ideas Rain Wizard 50-Gallon Barrel
This is a classic choice for homeowners. It holds 50 gallons and comes with a flat back that sits flush against your house. The included spigot makes filling watering cans easy. It also has a overflow hose that directs extra water away from your foundation. The plastic is UV-resistant, so it won’t crack in the sun. One minor issue: the screen on top can clog with leaves if you don’t clean it regularly.
2. RTS Home Accents 60-Gallon Wood-Look Barrel
If you want something that looks like a wooden whiskey barrel but is actually lightweight plastic, this is it. The 60-gallon capacity is great for medium-sized gardens. It has a brass spigot and a overflow fitting. The wood-look design blends well with most landscapes. However, the plastic can feel a bit thin compared to other models. Still, it holds up well for several seasons.
3. Algreen Cascata 65-Gallon Terra Cotta Barrel
This barrel looks like a large terra cotta pot, making it a stylish addition to any yard. It holds 65 gallons and has a child-proof lid for safety. The included diverter kit connects directly to your downspout. It also has a mesh screen to keep mosquitoes out. One downside: the terra cotta color may fade after a few years in direct sunlight. But overall, it is a solid performer.
4. FCMP Outdoor 50-Gallon Heavy-Duty Barrel
For those on a budget, this barrel offers great value. It is made from thick, UV-stabilized plastic that resists cracking. The 50-gallon capacity is enough for most small gardens. It includes a spigot, overflow hose, and a removable screen. The only complaint is that the spigot can be a bit stiff to turn at first. But it loosens up after a few uses.
5. Enviro World 75-Gallon Slimline Barrel
If space is tight, this slimline barrel is perfect. It holds 75 gallons but is only 22 inches wide. It fits nicely against a wall or in a narrow gap. The flat back allows for easy mounting. It comes with a diverter kit and a brass spigot. The only catch is that it is taller than standard barrels, so you may need a step stool to reach the top. Still, it is one of the most space-efficient options available.
How To Choose The Best Rain Barrel For Your Home
Picking the right barrel depends on your roof size, rainfall, and available space. Here is a step-by-step guide to help you decide.
Step 1: Measure Your Roof Area
Calculate the square footage of your roof that drains into your downspout. A 1,000-square-foot roof can collect about 600 gallons of water from just one inch of rain. So a 50-gallon barrel will fill up quickly. If you have a large roof, consider a barrel with 60 to 100 gallons capacity.
Step 2: Check Your Downspout Location
Your barrel needs to sit under a downspout or be connected via a diverter. Make sure the ground is level and stable. If your downspout is far from your garden, you may need a longer hose or a second barrel. Also, consider the overflow: you want excess water to flow away from your foundation.
Step 3: Choose The Right Material
Plastic barrels are lightweight and affordable. Metal barrels are durable but can rust. Wood barrels look nice but require more maintenance. Most homeowners prefer UV-resistant plastic because it lasts longer and is easy to clean.
Step 4: Look For Essential Features
- Screen or mesh to keep out debris and mosquitoes
- Overflow port to direct excess water
- Spigot for easy access (brass is better than plastic)
- Child-proof lid for safety
- Flat back for wall mounting
Installation Guide For Rain Barrels
Setting up your barrel is straightforward. Follow these steps for a secure and functional system.
What You Will Need
- Rain barrel with diverter kit
- Level surface (concrete paver or gravel pad)
- Hacksaw or pipe cutter for downspout modification
- Adjustable wrench
- Hose for overflow
Step 1: Prepare The Base
Place your barrel on a sturdy, level base. A concrete paver or a bed of gravel works well. The base should be slightly higher than the ground to allow gravity flow from the spigot. Make sure the barrel is stable and won’t tip over when full.
Step 2: Cut The Downspout
Measure and mark the downspout where you want the diverter to sit. Use a hacksaw to cut the downspout at the mark. Attach the diverter according to the manufacturer’s instructions. Most diverters have a flap that directs water into the barrel when it is not full.
Step 3: Connect The Overflow Hose
Attach the overflow hose to the barrel’s overflow port. Run the hose away from your foundation to a drain or garden area. This prevents water from pooling near your house. You can also connect multiple barrels in series using the overflow ports.
Step 4: Test The System
Wait for a rain shower or run a garden hose on your roof. Check for leaks at the spigot, diverter, and overflow connections. Tighten any loose fittings. Also, ensure the screen is in place to keep out leaves.
Maintenance Tips For Long-Lasting Barrels
With proper care, your barrel will last for years. Here are some simple maintenance tasks.
Clean The Screen Regularly
Leaves and debris can clog the screen, reducing water flow. Clean it every few weeks during the rainy season. Use a brush or rinse it with a hose. If the screen is damaged, replace it to keep mosquitoes out.
Drain And Store In Winter
If you live in a freezing climate, drain your barrel before the first frost. Water expands when it freezes, which can crack the barrel. Store it upside down or in a shed. Some barrels are freeze-proof, but it is safer to empty them.
Check For Leaks
Inspect the spigot and connections for drips. Tighten them with a wrench if needed. If the barrel develops a crack, you can patch it with a plastic repair kit. Small leaks are easy to fix if caught early.
Prevent Algae Growth
Algae can grow if the barrel is exposed to sunlight. Use an opaque barrel or paint it with a dark color. You can also add a few drops of bleach (1/8 teaspoon per gallon) to keep the water clear. But do not use bleach if you plan to drink the water (rain barrels are not for drinking unless treated).
Common Mistakes To Avoid
Even the best rain barrels can fail if installed poorly. Here are pitfalls to watch out for.
- Placing the barrel on uneven ground, causing it to tip
- Forgetting to add an overflow hose, leading to foundation damage
- Using a barrel without a screen, inviting mosquitoes
- Connecting the barrel to a downspout that drains a dirty roof (like one with bird droppings)
- Not securing the lid, which can be a hazard for children or pets
Frequently Asked Questions
What Size Rain Barrel Do I Need?
For a small garden, a 50-gallon barrel is usually enough. For larger gardens or frequent watering, consider 60 to 100 gallons. You can also connect multiple barrels together for more capacity.
Can I Drink Water From A Rain Barrel?
No, rain barrel water is not potable unless you treat it with a filtration system. It is safe for watering plants, washing cars, or flushing toilets. Always label your barrel as non-potable.
How Do I Prevent Mosquitoes In My Rain Barrel?
Use a fine mesh screen on the top and keep the overflow hose covered. Mosquito dunks (containing BTI) are safe for plants and kill larvae. Check the screen regularly for holes.
Do Rain Barrels Need To Be Elevated?
Elevating the barrel by 12 to 18 inches improves water pressure from the spigot. A concrete block or wooden stand works well. Just make sure the base is stable.
Can I Use A Rain Barrel In Winter?
In freezing temperatures, drain the barrel and disconnect the hoses. Ice can crack the plastic. Store the barrel indoors or upside down until spring. Some models are rated for cold weather, but it is best to empty them.
