Challenge Definition

The lack of adequate sanitation facilities is a global problem with an estimated 2.3 billion people using unimproved toilets or no toilets at all when eliminating waste. This problem leads to significant public health issues with an estimated 280,000 diarrheal deaths per year attributable to inadequate sanitation. Poor sanitation is also a major factor in several neglected tropical diseases, including intestinal worms, schistosomiasis, and trachoma as well as contributing to malnutrition. World Vision, supported by SeaFreight Labs, is seeking novel new ideas, concepts, and approaches to attack the lack of adequate toilets and latrines in some of the poorest areas of the world.


This is an Ideation Challenge with a guaranteed award for at least one submitted solution The detailed problem statement is available HERE.
