Climate Change and Drought Are Forcing Us to Upgrade Our Water Systems

Climate change predictions and areas of severe drought in the US and around the globe have put water high on the list of global crises. The answer is “Water 4.0,” argues David Sedlak, a professor of civil engineering at the University of California-Berkeley.

What’s Water 1.0? To understand that, you have to understand how we got the water system we have now — and where it might be going. First, says Sedlak, there was Water 1.0, when Rome built aqueducts to bring in water and dispose of waste. Water 2.0 saw 19th century Europeans chlorinate and filter drinking water. That was followed by our present system, Water 3.0, which treats sewage, as well as drinking water.

Now it’s time for Water 4.0, David Sedlak argues in his new book, Water 4.0: The Past, Present, and Future of the World’s Most Valuable ResourceSedlak is co-director of the Berkeley Water Center and he takes comfort in the history of water supply innovation.
