The need to find new water sources is critical, according to Stan Williams, vice president of project development for Poseidon Water in Carlsbad.

“Global water consumption is doubling every 20 years, and all accessible fresh-water resources are already allocated,” Williams told the Rotary Club of Los Altos Jan. 28.

Williams, who moved to the private sector after 13 years as CEO of the Santa Clara Valley Water District, mentioned desalination of seawater as a solution to the state’s pressing water needs.
