Linda Poon of NPR uses the word poop in her headline, so I guess I can too! This article about Bill Gates drinking a glass of water derived from sewage sludge makes me very happy. This process has derisively – and misleadingly – been called “toilet to tap” (a technology I mentioned in this post), and as such it has scared people away from an extremely effective way of recycling precious water. This appears to be a different technology from the classic method of collecting and treating water from sewage, but the results are the same. This is the sort of innovation the world needs. People just need to put on their critical thinking caps and realize that the initial source, while gross to think about, is irrelevant to the ultimate product: clean, drinkable water.
