In the future we will all drink delicious, refreshing, toilet water
The future of clean drinking water just might be in your toilet. That probably grosses you out. And that’s the problem. The issues surrounding recycled wastewater are more psychological than scientific.
“Here’s a secret: You probably already are. But as we need to find ways to conserve water, treated wastewater may become a more obvious part of what we drink. The trick to making that work isn’t technological, it’s psychological.
Despite the fact water engineers have the technology to make ultra-pure water, she [Linda MacPherson] says, and the more advanced techniques–reverse osmosis, advanced oxidation, or filtration–can remove harmful chemicals down to parts per trillion and parts per quadrillion, the powerful notion of disgust persists. This psychological front represents the biggest challenge to the future of clean water. How do you break the cognitive link and remove the psychological sewage after the actual sewage is long gone? One way might be adding successive rounds of purification or even sticking cleaned water back in a river or a stream (although Nemeroff points out: “The irony is that when you put this ultra-pure water in the natural world, it’s actually making it dirtier to become acceptable.”)”
Flushing toilet water down your throat sounds delicious, no?
