Carlsbad Desalination Construction Project
In December 2012, Poseidon Water finalized a 30-year water agreement with the San Diego County Water Authority for the purchase of 50 million gallons per day of desalinated seawater and secured financing for the Project. The water will be produced at the desalination plant being built in Carlsbad and conveyed to the San Diego County Water Authority’s water system via a 10-mile pipeline.
Poseidon Water has contracted with a joint venture of Kiewit Infrastructure West and J.F. Shea Construction, Inc., to design and build the desalination plant and pipeline. IDE Technologies, Ltd., a world leader in desalination technology and operations, will engineer the desalination plant’s design and equipment and handle plant operations.
Construction on the plant began in late 2012 and pipeline construction began in spring of 2013. Pipeline installation is currently underway in Carlsbad and Vista. In San Marcos, construction is nearing completion as crews are working to restore and repave streets where pipeline installation occurred. To keep the public informed about the progress of construction, Poseidon Water will provide regular construction updates on this website related to timing and potential detours and closures. Poseidon Water will work to minimize impacts to nearby businesses, residents, and commuters during construction. We appreciate your patience during this vital water supply project.
