In the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, Doulaye Koné, senior program officer for sanitation technologies and tools at the foundation, discusses progress made in and future steps for the “Reinvent the Toilet Challenge: India” (RTTC), a program aimed at developing safe and affordable sanitation. After visiting New Delhi to review progress on the program, Koné notes, “It was amazing to see so many ideas and technologies integrated into devices that can safely collect and processes human waste. … I left Delhi full of optimism and confident that the sanitation challenges faced by the community, and particularly girls and women, in Jain Mandir Cluster can be resolved with innovative technologies and great services. I remain very optimistic that our partners are on the right paths to transform the health and lives of billions people in years to come” (4/11).
