A rain barrel is a container, typically positioned beneath a downspout, capturing and storing rainwater runoff from a roof for later use, most commonly for garden watering, offering a simple way to conserve water while reducing immediate stormwater runoff from the property.
This straightforward water conservation approach has grown in popularity as homeowners increasingly seek ways to reduce water bills and environmental impact, with many municipalities and utility companies even offering rebates encouraging rain barrel installation.
Because standing water in a rain barrel can become a mosquito breeding ground if not properly managed, ensuring the barrel includes a secure, mesh-covered opening and periodically emptying accumulated water helps prevent this potential pest and health concern.
What Does a Rain Barrel Involve?
- A container positioned beneath a downspout
- A diverter or direct connection capturing roof runoff
- A spigot for accessing stored water
- Mesh covering preventing debris and mosquito breeding
Why Are Rain Barrels Important?
By capturing and storing rainwater for later garden use, rain barrels offer genuine water conservation benefit, reducing both municipal water consumption for irrigation purposes and the immediate volume of stormwater runoff leaving the property during rain events. This dual environmental and cost-saving benefit has made rain barrels an accessible, popular sustainability improvement for many homeowners.
Because rain barrels typically overflow once full, connecting an overflow outlet to appropriate drainage, rather than allowing overflow to simply pool near the foundation, helps ensure this water conservation practice doesn’t inadvertently create the moisture problems proper downspout drainage is meant to prevent. This thoughtful setup ensures the water conservation benefit doesn’t inadvertently create a different problem.
Rain Barrel vs. Rainwater Harvesting
A rain barrel is a simple, single-container water collection device. Rainwater harvesting is the broader concept and practice, which can include rain barrels along with more elaborate collection and storage systems for larger-scale water conservation.
