"Imagine you live on a floating lake house. Open air. Chirping crickets. Clear, starry nights. Everything seems great until you need to use the bathroom. The natural instinct might be to make a deposit in the water. But that wouldn't be safe. Microbes in your feces would contaminate the water and could cause outbreaks of deadly diseases, like cholera. A group of engineers in Cambodia wants to solve that problem for the floating villages of Tonle Sap Lake, the largest freshwater lake in Southeast Asia. Over a million people live on or around it. Exposure to wastewater spawns diarrhea outbreaks each year. In Cambodia, diarrheal diseases cause 1 in 5 deaths of children under age 5." - rønin
