A rain barrel is a closed barrel, usually connected to a downspout where it collects water from a “catchment area,” typically a roof. Rain barrels can also be left in the garden to simply collect what falls into it, though this method is obviously much slower. The square footage of the roof or other catchment surface provides a basis for calculating how much rain water is likely to be collected. A rule of thumb is that a catchment area of 1,000 square feet will yield the 600 gallons of water referenced above, for every inch of rain that falls. With average rainfall in the United States ranging from approximately 4 inches to 187 inches, a rain barrel can provide a significant portion of a household’s water supply. Near the bottom of the rain barrel is a spigot, through which the water flows. The spigots should be designed so that a hose can be attached directly to the rain barrel for ease of watering.
