That’s the bad news. The good news is that populist logisticians are at work on the problem. There’s an article in the NYTimes today about “the Greywater Guerrillas, a team focused on promoting and installing clandestine plumbing systems that recycle gray water–the effluent of sinks, showers and washing machines–to flush toilets or irrigate gardens.”
