As part of the project, they will offer more than USD 1.5 million in grants to 11 projects funded across different countries, including India, Bangladesh, Liberia and Malawi among others.
Of the 11 projects, three have been selected from India.
One the projects is by the Center for Environmental Planning and Technology on how bring sustainable and equitable sanitation services can be brought to small and medium towns in Maharashtra.
The others are by Infrastructure Development Corporation to create partnerships for urban sanitation service delivery in Chitradurga (Karnataka) and by Administrative College of India to identify how to deliver sustainable and equitable sanitation services in Warangal (Telangana).
"Delivering sanitation services is challenging, expensive and often ineffective, particularly for the poorest communities," Bill and Melinda Gates Foundation Director of the Water, Sanitation, and Hygiene programme Brian Arbogast said.
