Why Flush Toilets are Wasteful

Every time a toilet flushes, a gallon and a half of clean, treated water is wasted.

“We use drinking water to flush our toilets,” said Lena Trotochaud, a research scientist with the Duke University Center for Water, Sanitation, Hygiene and Infectious Disease (WaSH-AID). “And as climate continues to change and water becomes more scarce, and we have more droughts and more fires, we’re going to be using more and more drinking water and having less and less of it. We really need to conserve that precious resource.”
