Here’s a great idea from some folks in Oregon: use the treated wastewater produced from sewage to brew beer. Writing on the NPR blog The Salt, Cassandra Profita discusses the process by which clean, drinkable water can be produced from sewage sludge. Although Oregon does not approve this water for consumption, a new experiment is allowing small craft brewers to use this water in their beer. This is a terrific idea. People get grossed out by the idea that the water came from sewage, but as I have written about before, this is a mental and cultural block. There is no reason to fear drinking water that has been reclaimed from waste; consider the fact that most of our municipal water sits in reservoirs filled with fish and plant matter, as well as trash, fuel and oil residue from boats, and other unsavory flotsam and jetsam. That water goes through the same treatment process as wastewater. So why not use it? Drought conditions and continued water scarcity means we need to look at every option, and as far as I can tell there is no downside here.
Why Dump Treated Wastewater When You Could Make Beer With It?
