For the second consecutive year, a public opinion survey shows San Diego County residents overwhelmingly support the diversification of San Diego County Water’s water supply portfolio. Two-thirds of respondents to the survey considered the development of seawater desalination as a new, local water supply a “good idea.” Respondents also indicated strong approval for building seawater desalination facilities adjacent to existing power plants along the San Diego County coast.
The results of the telephone survey, conducted in May and June 2004 by the firm of Rea & Parker Research and the SDSU Social Science Research Laboratory, were presented to the Water Authority board today.
“Public understanding of, and support for projects that diversify San Diego County’s water supply are critical to the Water Authority’s mission,” said Bernie Rhinerson, Water Authority board chairman. “The poll results show that county residents are very knowledgeable on water issues and understand the role diversification plays in proving the region’s water supply reliability.”
On June 24, 2004, the Water Authority board of directors voted unanimously to add seawater desalination and 21 other water supply diversification projects to the agency’s Capital Improvement Program.
Survey respondents also strongly support using recycled water to improve water supply diversity and reliability, especially for landscape irrigation and manufacturing.
Among key findings of the survey:

In addition, 75 percent support constructing a facility in San Diego County and 72 percent support locating facilities adjacent to existing power plants along the coast.
