What happens when you flush your toilet? Environmental engineer and writer Alice Outwater knows, and she guides the reader through the technical ins and outs of such delicate matters as water treatment and sewage handling--subjects she writes about with considerable charm. Here you will learn how "raw sludge brew" is separated, how methane from sewage is converted to a source of power, and how aqueducts past and present really work. Outwater also describes in lay terms the complex ecology of rivers, making a strong case for the preservation of free-flowing streams in the place of dammed waterways. Her book is somewhat more narrowly focused than the title suggests, but it is highly interesting and instructive nonetheless. [via]
