UC Berkeley professor, David Sedlak, joins The Water Values Podcast to discuss the revolutions in urban water systems and to forecast what the next generation of our urban water systems will look like, which he calls Water 4.0. Dr. Sedlak takes us through the circumstances that surrounded the development of major technological revolutions in how water was supplied, treated and disposed of, and he’s got intriguing and provocative ideas on the need for and shape of a new revolution in our urban water systems.
