"Anyone with a roof on Planet Earth can harvest rain water. From Mexico City to Calcutta or Los Angeles to Beijing. One inch of rain fall on a 1,000 foot surface will yield approximately 500 gallons of soft, untreated rain water. It’s a huge source of water as close as your nearest down spout. So liberate your down spout today and harvest the rain!"

-Dan Borba, Harvesting Rain Water Since 1999
