A rain barrel and a garden hose walk into a bar… The bartender says, “Hey, no refills!”
Collecting rainwater is an eco-friendly and cost-effective way to manage water needs. If you’re in the market for the best rain barrels, there are several key factors to consider before making a purchase. Here are the top five considerations to ensure your pick serves your needs.
Top Considerations Before Selecting a Rain Barrel
Capacity
Water needs and usage patterns. If searching for the best rainwater barrels for gardening, some good questions to ask include, “How big is my garden?” “How frequent do I need to water my plants?” If used for purposes other than irrigation, consider factors like the size of your household will determine the frequency of water usage hence barrel capacity. Another determining factor is the size of the roof. We want to hit a sweet spot to avoid frequent refills or overflows.
Other considerations when looking at capacity include rainfall patterns. If your area receives prolonged rainfalls or falls in a cool and wet climatic condition, you may consider going for larger capacity barrels. The average American home can function comfortably with 50 gallon to 150 gallon barrels.
Here’s a simpler way to look at it. 0.25-inches of rain hitting a 600-square-foot roof will result in 90 gallons of water.
Material
Rain barrels are typically made of polythylene, metal, polyethylene resin, PVC or wood. High-density plastic is more popular among homeowners due to its affordability, lightweight appeal, and its resistance to rust and rot. It’s also easy to transport and clean, lowering maintenance costs.
That said, if you’ll be placing your rainwater collection barrel outside, consider the degrading effects of sunlight to plastics. Clay and stone barrels could solve this as they prevent sunlight and has insulating properties that maintain temperatures inside. This additionally prevents growth of algae. That said, clay and stone barrels contain smaller water quantities.
Homeowner’s who opt for an aesthetic appeal can go for wooden barrels. These blend well with surroundings with a rustic appeal. However, maintenance cost could be higher with wooden barrels.


Design and features
Rain barrels come in various designs, including traditional barrel-shaped barrels and more modern, sleek designs. Choose a design that complements your home’s aesthetic. Extra features to watch out for include screen filters to keep debris at bay, overflow spouts, and child safety locks if you have kids. For a larger integrated design, consider buying rain barrels with linking systems that connect multiple barrels.
Installation
Consider how easy installing and maintaining the rain barrel is. For easy usage, look for features like
• Secure Lids: Keeps the water clean.
• Overflow Valves: Helps manage excess water.
• Hose Connections: Facilitate easy water usage.
Federal and State regulations
Local regulations may bar rainwater collection due to factors such as natural infiltration during harvesting, water rights, and the reduction of downstream water. Some regulations limit the usage of rain collection systems due to plumbing, health, or water usage codes. While other states may encourage rainwater collection, we recommend checking with your local regulations before installing.
