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. You’ll really enjoy hearing David speak about Water 4.0.

In this Session, You’ll Learn about:

  • The first revolution in urban water systems that the Romans pioneered
  • The second revolution in urban water systems that led to water filtration and chlorination
  • The third revolution in urban water systems that treated wastewater
  • The need for a fourth revolution in urban water systems
  • Sea water desalination
  • Water reuse
  • Distributed water systems
  • The impact of the droughts in California and Texas on accelerating technological innovation
