Living without a toilet is more than an inconvenience. It’s dangerous. Unsafe sanitation means contaminated water, soil, and food. It causes illness and death.

According to the latest estimates, diarrhea and other sanitation-related diseases kill nearly 500,000 children under the age of five every year.

As the world gets more crowded, the human toll of unsafe sanitation will only increase. The United Nations estimates that between now and 2050, the world’s population will grow by two billion people. More than 90 percent of that growth will be concentrated in cities and in developing countries—places that are least likely to have good sanitation.

The COVID pandemic has also served as a powerful reminder of the urgent work households and cities must do to contain and treat deadly pathogens.

In 2011, our foundation’s Reinvent the Toilet Challenge asked researchers if they could develop safe sanitation solutions that work without relying on sewage systems or running water. (Sewers and treatment plants have historically been the best way to safely process waste, but they are extremely expensive to build, maintain, and operate. They also rely on large amounts of water when many countries are suffering from water shortages.)
