Recycling sewage into drinking water may sound gross, but it's one of many ideas being floated at this year's Chicago Water Week.
The big picture: To better understand this alternative to diverting H20 from water-rich areas like ours, Axios talked to Peter Annin, author of "Purified: How Recycling Sewage is Transforming our Water."
- He'll speak at the Shedd Aquarium on Thursday.
His biggest surprise: How many communities are already drinking former sewage, including Orange County, California; San Diego; El Paso and more.
- "It is happening all over the Sunbelt and most people don't even realize it," Annin tells Axios.
The big takeaway: "There are only two realistic options left for 'new' water supplies: the ocean and the toilet, and that the toilet is the more sustainable option — as long as people can just get over the yuck factor," he says.
Zoom in: Closer to home, Green Bay Packaging is using "recycled sewage to make their paper and not discharging any wastewater into the once notoriously polluted Fox River," Annin says.
The intrigue: Rare earth minerals may be the next resource scientists extract from wastewater, according to new research.
- UChicago researcher Chong Liu and others will talk about a process to pull lithium from "dilute sources" on Tuesday night in a program that is already filled up.
