The Water, Sanitation, & Hygiene Program at the Bill & Melinda Gates Foundation is inviting innovators to send letters of inquiry for round 3 of the Reinvent The Toilet Challenge.
Successful applicants will receive grants to design, prototype and test on-site, self-contained sanitation modules for individual families or neighbourhoods. Self-contained means no connections to piped water, sewerage or energy (electricity/gas) utility services.
Capital and operational costs should not exceed US$ 0.05/user/day. Designs should be able to deal with sanitary products like paper, cloth, sand, and other personal hygiene products and chemicals.
There is a two-step application process:
1.Submission of a Letter of Inquiry (LOI) in the form of a 5 page concept note by 8 November 2012, 11:00pm PST
2.Eligible applicants will be requested to submit a full proposal
