What can I use as a rain barrel?

You can use a variety of containers as a rain barrel to collect rainwater, including repurposed food-grade plastic barrels, large trash cans, or even specialized rain barrels designed for this purpose. The key is to ensure the container is clean, durable, and can be fitted with a spigot for easy water access.

What Can I Use as a Rain Barrel? Creative and Practical Solutions

Collecting rainwater is a fantastic way to conserve water, reduce your reliance on municipal water sources, and provide your garden with naturally soft, chemical-free water. But what exactly can you use as a rain barrel? You don’t always need to buy a fancy, purpose-built unit. Many everyday items can be repurposed effectively.

Repurposed Food-Grade Barrels: The Classic Choice

When people think of DIY rain barrels, food-grade plastic barrels often come to mind. These are typically large, durable containers that once held ingredients like olives, pickles, or syrups. They are an excellent option because they are designed to be robust and, importantly, food-safe, meaning they won’t leach harmful chemicals into the water you collect.

Where to find them: Look for them at local restaurants, food processing plants, or online marketplaces.
Preparation: Thoroughly clean the barrel with soap and water. Ensure all food residue is removed.
Modifications: You’ll need to cut an opening at the top for rainwater to enter, usually from your downspout. You’ll also need to install a spigot near the bottom for dispensing water.

Large Trash Cans: An Accessible Alternative

For a more readily available option, consider using large, sturdy trash cans. These are often made of durable plastic and come in various sizes, making them adaptable to different needs and downspout configurations.

Material matters: Opt for heavy-duty plastic trash cans, preferably opaque, to prevent algae growth.
Lid security: Ensure the lid fits snugly to keep out debris and pests. You may need to modify it to connect to your downspout.
Spigot installation: Similar to barrels, a spigot will need to be installed near the base.

Specialized Rain Barrels: Designed for the Job

While repurposing is cost-effective, specialized rain barrels offer convenience and often come with features like built-in screens to filter debris and overflow spouts. These are designed specifically for water collection and can be more aesthetically pleasing.

Variety of styles: Available in many shapes, sizes, and colors to match your home’s exterior.
Integrated features: Many include child-resistant lids, overflow hoses, and even decorative elements.
Ease of setup: Generally straightforward to connect to your existing downspout system.

Other Creative Container Ideas

Beyond the most common options, a bit of creativity can unlock other possibilities for your DIY rain barrel project. The primary considerations are volume, durability, and the ability to safely dispense the collected water.

IBC Totes: These large, caged plastic tanks can hold a significant amount of water. They often come with a built-in valve that can be adapted.
Large Water Coolers: If you have access to old office water cooler jugs, these can be a smaller-scale solution.
Stock Tanks: Metal or plastic stock tanks used for livestock can also be adapted, though they are often quite large.

Key Considerations for Any Rain Barrel Choice

Regardless of what you choose to use as a rain barrel, several factors are crucial for success and safety.

1. Material and Durability

The container must withstand outdoor conditions and the weight of potentially hundreds of gallons of water. Food-grade plastic is ideal. Avoid materials that could degrade quickly or leach toxins.

2. Water Collection and Overflow

How will the water get into your chosen container? You’ll typically need to divert your downspout. Also, consider what happens when the barrel is full. An overflow mechanism is essential to prevent flooding around your home’s foundation.

3. Accessing the Water

A spigot is a must-have. It allows you to easily fill watering cans or connect a hose. Position it a few inches from the bottom to avoid drawing sediment.

4. Keeping it Clean and Safe

Screens: A mesh screen over the opening prevents leaves, debris, and mosquitoes from entering.
Lids: A secure lid is vital for safety, especially if you have children or pets. It also helps prevent algae growth.
Regular Cleaning: Periodically drain and clean your rain barrel to maintain water quality.

Setting Up Your Rain Barrel: A Quick Guide

Once you’ve selected your container, the setup process is generally consistent.

Prepare the Container: Clean it thoroughly. Cut an inlet hole for your downspout. Install a spigot near the bottom.
Position the Barrel: Place it on a stable, elevated platform (like concrete blocks) to increase water pressure and make filling watering cans easier.
Connect the Downspout: Divert your downspout so it feeds directly into the inlet hole. You may need an elbow or flexible tubing.
Install Overflow: Attach a hose or pipe to direct excess water away from your foundation.
Test and Use: Fill it with a hose to check for leaks, then let nature do the rest!

### What is the best material for a rain barrel?

The best material for a rain barrel is typically food-grade plastic. This ensures the water collected is safe for gardening and won’t leach harmful chemicals. Opaque plastic is preferred as it helps prevent algae growth. Durable, UV-resistant materials are also important for longevity.

### How do I stop mosquitoes from breeding in my rain barrel?

To stop mosquitoes, ensure your rain barrel has a tight-fitting lid and a fine mesh screen over the inlet. This prevents them from getting inside to lay eggs. If you have an overflow, ensure it also has screening. Regularly check for any potential entry points.

### Can I connect multiple rain barrels together?

Yes, you can connect multiple rain barrels together to increase your water storage capacity. This is typically done by drilling a hole in the side of one barrel and connecting it to the next with a hose or pipe, usually positioned a few inches from the bottom. This allows water to flow from the first barrel to the second once the first is full.

### How high should a rain barrel be off the ground?

A rain barrel should ideally be elevated at least 12-18 inches off the ground. This elevation provides enough gravity-fed pressure to operate a spigot effectively, making it easier to fill watering cans or connect a hose. Using cinder blocks or a sturdy stand is a common method.
