‘Taking the Waste Out of Wastewater’ – NYTimes.com

23 Apr

While we can’t “make” more water, there is one solution to water shortage problems that addresses issues of both quality and supply. Without mining an ancient aquifer, draining a natural spring or piping in the pricey harvest from a greenhouse-gas-and-brine-generating desalination plant, there is a solution to provide a valuable source of extremely pure water: reclaim it from sewage. The stuff from our showers, sinks and, yes, our toilets. In Israel, more than 80 percent of household wastewater is recycled, providing nearly half the water for irrigation. A new pilot plant near San Diego and a national “NEWater” program in Singapore show it’s practical to turn wastewater into water that’s clean enough to drink. Yet, in most of the world, we are resistant to do so.

Why?

We think we are rational beings, but we are not. We are emotional creatures, subject to obscuring feelings like fear and disgust. … While recycled water may be a smart and clean way to manage our water supply, our primitive instincts are more programmed to fear the murky water hole than to worry about climate change, new contaminants and population growth.
