Why Collecting Rainwater Is a Smart Choice for Homeowners

Rainwater harvesting offers significant economic benefits by reducing water bills up to 40% annually for typical households. You’ll immediately lower your dependency on municipal water supplies while creating a sustainable water source for your garden and lawn. During drought restrictions, your plants won’t suffer as you’ll have reserves ready.

Beyond cost savings, collected rainwater is naturally soft and free from chlorine, making it ideal for plant growth. Your garden plants will thrive with this pure water source that contains nitrogen and other nutrients absent in tap water. Many gardeners report healthier plants and increased yields when using rainwater exclusively.

Environmental benefits extend beyond your property line. By capturing rainfall, you’re reducing stormwater runoff that can overwhelm local drainage systems and contribute to erosion. You’re also conserving precious drinking water supplies that face increasing pressure from population growth and climate change impacts.

Key Features to Consider When Choosing a Rainwater Barrel

Capacity and Size

The capacity of your rain barrel directly impacts how much water you’ll collect during rainfall events. Most residential barrels range from 45-137 gallons, with 50-60 gallons being the most common. Consider your garden size, local rainfall patterns, and available space when selecting capacity. Larger barrels like the Graf Mondo (137 gallons) maximize collection, while compact options like the FCMP Outdoor Catalina (45 gallons) work well in limited spaces with their flat-back design.

Material and Durability

Rain barrel materials significantly affect longevity and functionality. UV-resistant polyethylene is popular for its balance of durability and affordability, like in the FCMP Outdoor Catalina. For maximum durability, look for double-wall construction (Algreen EcoCascata) or steel-reinforced sides (Graf Mondo). Food-grade plastic barrels, such as the Great American Rain Barrel’s repurposed olive containers, offer both safety and sustainability while resisting weathering, fading, and cracking over multiple seasons.

Design and Aesthetics

Your rain barrel will be a visible part of your landscape, so appearance matters. Many modern options feature decorative designs that complement home exteriors. The Good Ideas Impressions Nantucket model includes an integrated planter, creating a dual-purpose aesthetic element. Some barrels offer discreet profiles that meet HOA standards, while others like the Algreen EcoCascata’s vase-like shape serve as focal points. Consider barrel shape—rectangular maximizes storage space while rounded designs often blend better with landscaping.

Filtration and Overflow Systems

Effective filtration prevents debris and insects from contaminating collected water. Look for barrels with mesh screens like those on the FreeGarden RAIN and Good Ideas models. Proper overflow management is crucial for preventing foundation damage during heavy rainfall. The best systems include dedicated overflow ports with hose attachments, like the Great American Rain Barrel’s 3/4″ overflow valve or the Algreen EcoCascata’s 6-foot hose. These features protect your home while ensuring excess water gets directed where you want it.

Installation Tips for Your New Rainwater Barrel

1. Choose the Right Location

Positioning your rain barrel correctly is crucial for maximum collection efficiency. Place it directly under a downspout where rainwater naturally flows from your roof. Ensure the ground is level and stable to prevent tipping, especially when the barrel fills with water. For easier access to collected water, consider placing your barrel near the garden or areas where you’ll frequently use the water.

2. Create a Stable Foundation

Your rain barrel will weigh over 400 pounds when full, so a solid foundation is essential. Use concrete blocks, pavers, or a specially designed rain barrel stand to elevate your barrel about 12-18 inches off the ground. This height creates better water pressure for your spigot and makes it easier to position watering cans underneath.

3. Connect to Your Downspout

For proper water collection, you’ll need to modify your existing downspout. You can either:

• Cut the downspout above the barrel and attach an elbow to direct water into the barrel
• Install a diverter kit that redirects water to your barrel while allowing excess to continue down the original downspout
• Use a rain chain or flexible downspout extension to guide water into the barrel’s top opening

4. Set Up Overflow Management

Heavy rainfall can quickly fill your barrel, so proper overflow handling is critical. Most quality barrels include an overflow port near the top. Connect a garden hose or overflow pipe to this port and direct it away from your home’s foundation to prevent water damage. For maximum efficiency, consider linking multiple barrels in series to increase capacity.

5. Install a Debris Screen

Prevent leaves, twigs, and mosquitoes from entering your barrel by installing a fine mesh screen over all openings. Many barrels come with built-in screens, but if yours doesn’t, add one to the top inlet. Clean this screen weekly during heavy foliage seasons to prevent clogging and ensure clean water collection.

6. Prepare for Seasonal Changes

In regions with freezing temperatures, proper winterization is essential. Before the first frost, drain your barrel completely, disconnect it from the downspout, and store it upside-down for winter. Leave the spigot open to prevent damage from any remaining water that might freeze. Reconnect your downspout to ensure proper drainage during winter months.

7. Test Your System

After installation, test your system during the next rainfall or by running water from a hose into your downspout. Check for leaks around connections, proper overflow function, and spigot operation. Make adjustments as needed before relying on your system for regular water collection.

Maintenance and Seasonal Care for Rainwater Barrels

Collection

Collection is the first step in maintaining your rainwater barrel system. Ensure your rain barrel is properly connected to the downspout of your gutter system for maximum water capture. Install a debris screen at the inlet to prevent leaves, twigs, and other materials from entering the barrel. This simple addition will significantly improve water quality and prevent clogging in your system.

Storage

Proper storage maintenance ensures your rainwater stays clean and your barrel remains functional. Inspect your barrel regularly for signs of damage such as cracks or leaks that could compromise water collection. Clean the debris screen approximately once a week, especially after storms, to maintain optimal water flow and prevent mosquito breeding. This regular maintenance routine will extend the life of your system and improve water quality.

Distribution

Your distribution system determines how effectively you can use collected rainwater. Use the barrel’s spigot to attach a garden hose or fill watering cans for your plants. If your barrel has a low spigot placement, consider elevating it on concrete blocks or a sturdy platform to improve water pressure and make access easier. This simple modification can dramatically improve the usability of your rainwater collection system.

Seasonal Care

Winter: Drain your rain barrel completely before freezing temperatures arrive to prevent ice expansion from damaging the container. Leave the spigot open to ensure any remaining water can drain out. In colder climates, you might need to disconnect and store the barrel indoors during winter months.

Spring: Before the rainy season begins, inspect your barrel and all components for winter damage. Clean the debris screen thoroughly, check all connections, and ensure the foundation remains level and stable. This seasonal checkup prepares your system for maximum collection efficiency.

Summer: During hot months, regularly monitor water levels and ensure overflow valves function correctly to prevent water from pooling around the barrel’s base. Check screens more frequently as summer storms can bring additional debris. Properly maintained barrels provide valuable water during summer dry spells when your garden needs it most.
