Collecting precipitation in rain barrels could result in significant savings for many people in India, according to an analysis of
precipitation data collected by a NASA satellite. Estimates showed that harvested rain could provide at least 20 percent of average indoor water demand, or entirely irrigate a household vegetable garden. The savings associated with a vegetable garden could be between 2,500 and 4,500 rupees per year (39 to 71 U.S. dollars) — an amount equivalent to half a year’s rent in an average 1-bedroom apartment in an Indian city. In a country where the distribution of potable water is a challenge, rainwater is an untapped resource that could provide significant benefits, the researchers write in the Urban Water Journal.
