Get ideas for how to catch, store, and use rainwater with cisterns, barrels, and rain chains
Rain barrels typically hold about 50 to 60 gallons each―enough to irrigate houseplants or pots on the deck. The best type is made of recycled food-grade plastic (or use a recycled wine barrel like the one pictured), with an intake line, spigot, overflow attachment, screen cover to keep out leaves, and removable solid cover.
Position the barrel beneath a downspout; to keep the rainwater pure, remove the solid cover an hour or two after rainfall has washed pollen and other pollutants off the roof.
Rain barrels cost about $100 to $150 each.
