Mobi-Water is a solar-powered system that allows the millions of people who use water tanks to ensure that water is not wasted. It monitors water levels, leaks, valves and pumps via a mobile phone app. Access to water affects over 16 million people in Kenya, and 300 million people in sub-Saharan Africa, Gacheru believes that better access to information within the water value chain will greatly alleviate this problem in the African water sector.
