Improved sanitation is essential to a healthy and sustainable future for the developing world. By improving how we deal with human waste, we can avert hundreds of thousands of deaths from sicknesses such as diarrhea and greatly reduce environmental contamination. The foundation is working with partners to develop and spur demand for transformative sanitation technologies, identify new delivery models, build markets, and advocate public policies that support improved sanitation in the poorest communities in the world.

In 2011, we launched the global Reinvent the Toilet Challenge to fund research and pilot testing of inventions including low-water or waterless toilets that do not require a sewer connection or electricity and cost around 0.3 Chinese yuan (five US cents) per user per day.

Two years later, we joined with the University of Science and Technology Beijing to bring the challenge to China.

In 2016, we launched the annual National Toilet Technology Innovation Contest in partnership with the former China National Tourism Administration to fund the development and application of cutting-edge toilet technologies that could benefit those in need both in China and around the world.
