The little-known story of the systems that bring us our drinking water, how they were developed, the problems they are facing, and how they will be reinvented Turn on the faucet, and water pours out. Pull out the drain plug, and the dirty water disappears. Most of us give little thought to the hidden systems that bring us water and take it away when we’re done with it. But these underappreciated marvels of engineering face an array of challenges that cannot be solved without a fundamental change to our relationship with water, David Sedlak explains in this enlightening book. To make informed decisions about the future, we need to understand the three revolutions in urban water systems that have occurred over the past 2,500 years and the technologies that will remake the system. The author starts by describing Water 1.0, the early Roman aqueducts, fountains, and sewers that made dense urban living feasible. He then details the development of drinking water and sewage treatment systems—the second and third revolutions in urban water. He offers an insider’s look at current systems that rely on reservoirs, underground pipe networks, treatment plants, and storm sewers to provide water that is safe to drink, before addressing how these water systems will have to be reinvented. For everyone who cares about reliable, clean, abundant water, this book is essential reading.

A fresh look at the world’s water crises, and the existing and emerging solutions that can be used to solve them It is not your imagination: water crises are more frequent. Our twentieth-century systems for providing the water that grows food, sustains cities, and supports healthy ecosystems are failing to meet the demands of growing population and the challenges brought on by climate change. But the grim news reports—of empty reservoirs, withering crops, failing ecosystems—need not be cause for despair, argues award-winning author David Sedlak. Communities on the front lines of previous water crises have pioneered approaches that are ready to be applied elsewhere. Some have resolved shortages by enhancing water-use efficiency, and others have used moments of crisis to resolve historic disagreements over water rights. Still others have employed treatment technologies that unlock vast quantities of untapped water resources. Sedlak identifies the challenges that society faces, including ineffective policies and outdated infrastructure, and the myriad of tools at our disposal—from emerging technologies in desalination to innovations for recycling wastewater and capturing more of the water that falls on fields and cities. He offers an informed and hopeful approach for rethinking our assumptions about the way that water is managed. With this knowledge we can create a future with clean, abundant, and affordable water for all.
