But for three billion other people around the world, the answer is much more complicated. The issue is intermittent water supply. Millions of households have access to water piped water, but the problem is that water only comes for a few hours at a time down Hobie Darva, a city of 1.1 million people in India. The local utility provides water once every 2 to 4 days and depending on the season in the neighborhood. Sometimes it takes up to 10 days to arrive on that day. As you can imagine, all the water intensive chores air safer that day. So you're washing your dishes. You're washing all your clothes and your saving all the water you can, because you don't know when water's gonna come on next. It's a pretty stressful day on that day of water delivery, and you're probably thinking that that sounds like a water shortage problem, and in some cases that's true. But more often than not. This is actually an energy scarcity problem. Let's think about that. For a second. Water needs to be pumped from somewhere on pumping, requires energy and to get pressured to flow through the pipes or to get water to flow through the pipes you need pressure on. That requires energy to. But to give you a sense of just how much energy were talking, about 3% of California's total energy consumption goes to pumping water to Southern California. That's a lot of energy, and if you're talking about a developed country, that's fine. But when you're considering under developed or developing nations and the nations that are struggling to provide even the basic energy demands for its citizens, well, now you can see how the water problem is intrinsically tied to the energy issue. Our vision is to create a world where every citizen has access to basic public service is we employ mobile technology to improve governance. How do we do it? We use human sensors. Simply put people on their mobile phones. We allow citizens to give feedback in real time about exactly what's happening to their water supply. Would take that information and give it to the water utility, making sure the right information gets to the right person at the right time. It's a live, human powered, smart, good solution to simplify water issues around the globe. Now, three years later, our social enterprises grown from just answering questions about when the water will turn on tau actually simplifying water delivery and urban environments all across India. Now what we do is we tackle the problem of managing existing resource is for example, let's say you're a next drop user. You get a text message saying in two hours water should arrive, but two hours later, you don't have water. You sent us a text message saying water didn't come in my area and we take that information and give it to the local utility where the engineer can look into the matter. Now let's say there was a pipe damage in your area, which now the engineer can diagnose instantaneously. The usual scenario days. Sometimes weeks passed before you the citizen get water on. The engineer is completely unaware that precious water is being wasted. Now, this is just one example of how we're using real time data and increased transparency to work with governments and citizens to make water supply and more efficient and equitable.
