The Bay Delta Conservation Plan for two new tunnels is estimated to cost $25 billion, but that doesnt include all of the litigation and the delays that will ensue. Instead of implementing a slightly less destructive plan for the Delta, we should invest in desalination plants for Southern California.
BDCP estimates it will take one every 13 miles on the southern coast to replace current water use. The biggest issue with desalination is power consumption and carbon footprint. Pairing these with nuclear plants solves this problem.
