In the second edition of the fair (the first was in Seattle in August 2012), more than 700 participants from about 47 countries gathered to discuss how to bring safe sanitation to the 2.5 billion people who lack access to it. The fair in India was co-hosted by the Government of India's Department of Biotechnology and the Bill & Melinda Gates Foundation, with the support of India's Ministry of Urban Development, and it showcased innovative products and approaches from various Gates Foundation grantees from across the world that aim to bring safe, affordable and sustainable sanitation to those who need it most.
The fair showcased prototypes from several of the research grantees of the Reinvent the Toilet Challenge, where innovative approaches are being used for the safe and sustainable management of human waste. In addition to these there were also several other projects from other investment areas of the Gates Foundation's Water, Sanitation and Hygiene Program – Urban Sanitation Markets, Building Demand for Sanitation, Policy & Advocacy, Monitoring & Evaluation. As part of this, Project Sammaan was also showcased at the fair by Quicksand.
