Providing accessible, safe, sustainable water and sanitation services to everyone on the planet is one of the most critical development challenges we face. This podcast focuses on how smart technology is being used in Kenya and the work that Oxfam and Diaspora AI are doing in the informal settlements of Nairobi. It showcases how it can ensure a more consistent and continuous water supply, and provides evidence to help hold services providers to account. Irene Gai, Water, Sanitation & Hygiene (WASH) Strategist from Oxfam Kenya will describe how the project came about using smart sensors in tanks and how this can work in a range of settings to advance greater interaction between systems, technology and accountability even in the most challenging of contexts.
