Could A Simpler Delta Tunnel Solve Years Of California Water Conflict?

California’s ambitious plan to build two giant water tunnels under the West’s largest estuary has been deemed too expensive by some of the water utilities that would have to pay for it. As a result, attention is turning back to a cheaper option: One tunnel instead of two. On October 17, the board of directors of the Santa Clara Valley Water District unanimously rejected the $17 billion twin-tunnel project, known as WaterFix, and instead expressed support for a smaller, single-tunnel alternative. The district serves more than 1 million people in Silicon Valley.
