It takes a lot of water to make beer, so it shouldn’t be a surprise that enterprising local brewers have been responding to water scarcity by using recycled waste water either to save water and money, or draw attention to the need to recycle water much more widely.

I first learned about this when I read an intriguing story in Reasons to be Cheerful, Purified Wastewater Is the Drink of the Future. Part of the story focused on how companies, cities and some countries are combating the ‘yuck’ factor, and that is where beer enters the picture.
