Poseidon Water Seawater Desalination Project at Huntington Beach


By: Brian Lochrie

Desalination (also called "desalinization" and "desalting") is the process of removing dissolved salts from water, thus producing fresh water from seawater.  Shortage of fresh drinking water has created the need for desalination .Desalination is practiced in 150 countries. As of June 30, 2015 total number of desalination plants worldwide is 18, 426. More than 300 million people around the world rely on desalinated water for some or all of their daily needs.

Desalination just took a huge leap forward in California. The biggest plant in North America, able to purify 50 millions of gallons each day, is now pumping water in Carlsbad, a city north of San Diego.  Desalination has evolved into a desirable water supply alternative by tapping the largest reservoir in the world-the Pacific Ocean. The plant’s completion is a feather in the cap for the builder, Poseidon Water, which hopes to follow suit with a similar desalination project in Huntington Beach. The Huntington Beach Desalination Plant has a potential to have significant economic benefits for the City of Huntington Beach and the region. Details of this project were presented by Brian Lochrie, President ComunicationsLAB at ASCE OC meeting on April 28, 2016. Attached PowerPoint presentation gives the details of the Huntington Beach Desalination project discussed by Brian at the meeting.
