Using Mobile Phones to Alert Households Waiting for ‘NextDrop’ of Water
Although nearly half of the world’s population now has water piped into their homes and there have been significant improvements to water access in recent decades, many people living in urban areas of developing countries still do not have easy access to this most basic resource. And even where pipes do reach the urban poor, water sometimes does not.
“Literally, people wait around their house until the water comes on,” said Anu Sridharan, a founder of a social enterprise called NextDrop. “We’ve met people who’ve missed weddings, funerals and meetings.”
If customers miss a water supply window, then they may have to wait two to 10 days for their next chance. Unreliable water supply is a serious impediment to health and economic development. In India, 250 million people rely on unreliable water systems.
