How desalination works

Excerpt: Five years ago, the Santa Cruz Water Department and neighboring Soquel Creek Water District formed an alliance to build a seawater desalination plant, one that would provide drought protection for the city and allow the district to reduce pumping from its overdrafted aquifers.

Excerpt: The environmental analysis of the plant, due late this year, will discuss subsurface intakes -- which regulators prefer because of the fewer potential impacts on marine life -- and why studies dating back to 2001 determined there were geological constraints. That has left the city to consider open-ocean intake at one of seven potential sites, each of which will require an offshore pipeline, pump station and new infrastructure for transporting the water to the plant.

Excerpt: Water is brought in from an open-ocean intake system, the design and location of which has yet to be determined. The city has anticipated needing up to 6.3 million gallons of water each day to produce 2.5 million gallons of drinking quality water, according to its intake study.
