In many cities in developing countries, residents have piped water supplies. But there's a catch: the water is only available through the pipes for a few hours at a time, and people have no way of knowing when that will be. As a result, residents (mostly women and the poor) spend their days just waiting for the water to arrive. Anu Shiridharan from NextDrop, one of the speakers at TEDxGateway, has a solution.Anu Sridharan graduated from the University of California, Berkeley in December 2010 with a Master's degree in Civil Systems engineering, and received her Bachelor's degree from UC Berkeley in 2009 as well.During her time there, Anu researched the optimization of pipe networked systems in emerging economies as well as business models for the dissemination of water purification technologies for arsenic removal in emerging economies. Anu also served as the Education and Health director for a water/sanitation project in the slums of Mumbai, India called "Haath Mein Sehat" where she piloted a successful volunteer recruitment and community training model.
