I’ve got a question for you: would you drink sewer water? Yeah, I’m not sure I would. But recycled wastewater might be in all our futures. To understand why, my colleague Erin Stone has a pretty enlightening story you need to read. We all know California has a water problem. The Colorado River, where we get most of our water in Southern California, is going through a “megadrought,” the worst in 1,200 years. Greenhouse gases just make it worse. As temperatures rise, less snow falls. That means there’s less snow melt to fill up our rivers and reservoirs.
