Why Build a DIY Rain Barrel System?

Before we dive into the how-to, let’s talk about why you should consider building your own rain barrel. The advantages are numerous:

Cost Savings: One of the most appealing benefits is the reduction in your water bill. By using collected rainwater for your gardening or other outdoor tasks, you’re using free water rather than paying for municipal water.

Water Conservation: Rainwater harvesting helps to conserve precious water resources. It’s a sustainable practice that reduces the strain on our municipal water systems, especially during dry periods.

Eco-Friendly Gardening: Rainwater is naturally better for plants than treated tap water. It’s naturally soft and free from chlorine and other chemicals that can harm plants and beneficial soil microbes.

Reduced Runoff: Rain barrels help to manage storm water runoff. By collecting rainwater, you’re lessening the burden on your local drainage system and potentially reducing the risk of erosion and flooding.

Simple DIY Project: Building a rain barrel is a straightforward project that doesn’t require a lot of expertise or specialized tools, making it accessible to almost anyone.

Gathering Your Materials: The Cheap Rain Barrel Shopping List

The key to building a cheap rain barrel is to be resourceful. Here are the materials you’ll need, with tips on where to find them without emptying your wallet:

1. The Barrel

Your most important component is a large container to collect the water. Here’s what to look for:

• Food-Grade Plastic Barrel: This is the most crucial part. Aim for a 55-gallon or larger food-grade plastic barrel. Why food-grade? These barrels were previously used to store food or beverages, making them safe and free from harmful chemicals. You can often find these used for free or at very low prices from sources like:
  • Local Food Processing Facilities: Call nearby factories that deal with food items, they sometimes sell their used barrels.
  • Online Marketplaces: Check sites like Craigslist, Facebook Marketplace, or even eBay for local sellers.
  • Recycling Centers: Some recycling centers may sell reusable containers.
  • Beverage Companies: Local breweries or soft drink manufacturers can be good sources.
• Avoid Non-Food Grade Barrels: Be careful about using barrels that previously contained chemicals or petroleum products, as they may leach harmful substances into your collected water.

2. Rain Diverter Kit

A rain diverter kit is designed to channel rainwater from your downspout into the barrel. While these can be purchased pre-made, you can also DIY this component:

• Pre-Made Kits: These are easy to install and often come with clear instructions. They typically include a diverter that fits into your downspout, a hose to connect to the barrel, and a filter to keep out debris. Check Amazon or your local home improvement store like Home Depot.
• DIY Diverter: If you’re up for a little more challenge, you can create your own diverter using a section of downspout, a few elbows, and some flexible tubing. While this requires more effort, it can significantly lower your project cost. You can find how-to videos on YouTube for example.

3. Spigot and Hose Adapter

To access the water, you’ll need a spigot installed near the base of the barrel:

• Plastic Spigot: A durable plastic spigot will do the trick. Look for one that’s easy to install with a threaded end. These are readily available at any hardware store, like Lowe’s.
• Hose Adapter: A hose adapter will allow you to connect a standard garden hose to the spigot, making watering your garden a breeze.

4. Overflow System

It’s essential to have an overflow mechanism to prevent your barrel from overfilling and potentially causing damage. Some options include:

• Overflow Hose: You can simply attach a length of flexible hose to the top of your barrel to divert excess water away from your foundation.
• Overflow Valve: A valve can be a more refined method for directing the overflow, particularly if you have specific areas where you want to direct excess water.

5. Additional Supplies

Here are a few extra items you’ll need:

• Drill and Drill Bits: For creating holes for the spigot and hose adapter.
• Saw or Utility Knife: For cutting the downspout if required for the diverter.
• Measuring Tape: To measure components for optimal placement.
• Teflon Tape: To seal the threads of the spigot and prevent leaks.
• Optional: Screen Mesh: To place over the inlet hole on your barrel to keep out leaves and debris.

Step-by-Step Guide to Building Your DIY Rain Barrel System

Now that you’ve gathered your materials, let’s get to building. Remember to prioritize safety throughout the process, and wear protective eyewear and gloves if necessary. Here’s a step-by-step guide:

Step 1: Prepare Your Barrel

Start by thoroughly cleaning your barrel. Use soap and water to scrub the interior and exterior, ensuring that any residue from previous contents is removed. Let the barrel dry completely.

Step 2: Install the Spigot

Determine where you want your spigot to be located, typically a few inches above the base of the barrel. Using your drill, make a hole that matches the spigot’s diameter. Wrap the spigot threads with Teflon tape before inserting it into the hole. Tighten securely.

Step 3: Install the Hose Adapter (If Applicable)

If your spigot didn’t come with a hose adapter, you may need to make another hole for the adapter. Repeat the steps from installing the spigot, adding Teflon tape and tightening.

Step 4: Install the Rain Diverter

This is where you’ll use either a pre-made kit or your DIY diverter components:

• Pre-made Kit: Follow the manufacturer’s instructions carefully to install the diverter into your downspout. Usually, you’ll need to cut a section of downspout for the diverter and attach the provided hose to your barrel.
• DIY Diverter: Position the elbow sections of downspout so that they guide the water towards your barrel. Secure everything with screws or rivets, and use flexible tubing to connect it to the barrel.

Step 5: Create an Overflow System

Decide how you’ll manage overflow. Attach your overflow hose to the barrel or install an overflow valve. Ensure that the overflow directs water away from your house foundation.

Step 6: Place your Barrel

Position your rain barrel directly below your diverter. It’s a good idea to place it on a stable surface such as concrete blocks or pavers to prevent it from tipping over. Ensure that it’s accessible and easy to access for filling watering cans or attaching a hose.

Step 7: Test Your System

Before you rely on it to water your garden, test your new system with a garden hose. Check for leaks, and adjust the placement of the diverter if needed. Verify your overflow system directs water away safely.

Tips for Maintaining Your Rain Barrel System

To ensure your rain barrel works efficiently and lasts for years, here are some essential maintenance tips:

• Annual Cleaning: At least once a year, empty your barrel and scrub the interior with a brush and soapy water. This will remove any sediment or algae build-up.
• Leaf Removal: If your system uses a screen over the barrel’s inlet, be sure to remove leaves and debris regularly to prevent clogs.
• Winterizing: Before the first frost, drain your rain barrel and disconnect any hoses or diverters to prevent damage from freezing.
• Check for Leaks: Regularly check all connections for any leaks. Repair any leaks immediately.
• Inspect for Pests: Look for any signs of pests such as mosquitoes. If they’re present, you can add a mosquito dunk to the water, which will kill larvae without harming your plants.

Maximizing the Use of Your Collected Rainwater

Now that you have your rain barrel system up and running, here are some ideas to utilize the free water:

• Watering Gardens and Lawns: Rainwater is ideal for irrigating your plants. Use a hose or watering can to water your flowers, vegetables, and lawn.
• Cleaning Outdoor Tools: Hose down dirty garden tools with collected rainwater.
• Washing Cars: You can even use collected rainwater for a quick car wash.
• Non-Potable Uses: Rainwater can be used for various non-potable purposes such as rinsing off muddy boots, cleaning patios, or even filling bird baths.
• Don’t Use for Consumption: Keep in mind that rainwater collected in this manner should not be used for drinking, cooking, or other purposes that could involve ingestion.

Legal Considerations and Local Regulations

Before you install your rain barrel, it’s essential to check your local regulations regarding rainwater harvesting. Some regions may have restrictions or permits required. Contact your local municipality or water authority to ensure compliance.
