He looks at water from historical, societal and political perspectives as well as environmental and technical. His goal is to give the lay reader an understanding of how modern society is using water and how much re-thinking we need to do to bring our world into balance with limited water resources. 

I have also enjoyed reading Cadillac Desert by Marc Reisner and Water Resources by Shimon Cohen-Anisfeld.
