Water 4.0: The Past, Present, and Future of the World’sMost Vital Resource is a new (2014) book by David Sedlak. In it he details “(t)he 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 in the near future.” Water 1.0 is what he calls the gravity-powered aqueducts engineered and built by the ancient Romans. “…(T)he addition of filtration and chlorine disinfection on the front end of water distribution systems…” he refers to as Water 2.0. “…(T)he installation of biological wastewater treatment on the sewer end…” is Water 3.0. And, solutions to the challenges we now face will bring Water 3.x – Water 4.0 to our communities. These solutions may be centralized, decentralized or some combination of both. Sedlak does a good job of recounting the history and explaining the options we have as we move forward. For anyone interested in an overview of the past, present and future of urban water, this book is well worth reading.
