Its probably one of the more satisfying and useful jobs in the world :) Water sit atop food, economic, social, cultural, survival issues, and its no surprise its demand vs supply drives a huge economy around it.
There are a lot of orgs out there doing good stuff. But somehow, to the major junta this is more of a coffe/cocktail conversation. Not really mainstream.
Therein lies a huge challenge. And water's kind of the tiger for ecological consciousness - a lot many other things follow.
