A rain barrel is a rain harvesting system that is connected to a downspout from your home. By collecting rainwater, you can conserve water and save money. Water collected in the rain barrel can then be used to water the garden, wash the car, or a variety of other outdoor uses.
Rain barrels are connected to a gutter's downspout to collect rainwater from the roof for use in the garden and other outdoor uses. Most problems with rain barrels can be easily avoided if water is not allowed to stand in the barrel for more than five to seven days.
Rain barrels help conserve water by collecting rainwater from the roof into a 50-55 gallon barrel connected to the downspout. Instead of watering from the tap or faucet, you can use the water collected in a rain barrel to keep your home's landscape well watered and growing.
Good water management practices require good drainage details from roof to foundation that work in such a way that water is directed downward and outward. Some critical components are roofs, doors, windows, crawl spaces and foundations.
Rainwater harvesting can be as simple as placing a barrel under a shortened downspout. Larger systems require more thought, but once the concept is understood, even larger systems seem simple. Download this fact sheet to learn about rainwater harvesting.
