ARCADIS-U.S., Inc. Design-Build-Operate Project
The Carlsbad Seawater Desalination Project provides San Diego area businesses and residents with a consistent, drought-proof supply of high-quality water, less than three years after construction, using world-class desalination technology.
Located 35 miles north of San Diego, CA in the City of Carlsbad, CA., this impressive project estimated at $922 million includes a 100 MGD nominal seawater intake, interconnecting civil works, conveyance pipeline and financing. It is funded with approximately 80 percent tax-exempt bonds and 20 percent private equity. With design of the project beginning January 2013, completion of the construction is anticipated in 2015. This construction effort marks a major milestone for seawater desalination in all of North America – as the largest desalination plant in the western hemisphere.
Competitively procured by Poseidon Water using a hybrid EPC / DBO model, the project team includes Kiewit-Shea Desalination functioning as a JV prime; ARCADIS-U.S. as the EPC engineer, and IDE Technologies as the process designer/operator in a 30-year operating agreement.
The construction process was presented significant physical constraints on the 5-acre site at an existing operational power generating station, together with schedule constraints of under 36 months allowed for design and construction. To address these issues, Kiewit, ARCADIS and IDE developed an integrated team to produce several hundred design deliverables in a 13-month period, and to significantly advance the construction ability of field operations staff. ARCADIS scope includes all detailed design engineering in support of plant construction, exclusive of detailed process design and engineering which was provided by IDE Technologies, Kadima, Israeli
Demonstrating a true economic stimulus, in excess of 200 direct construction and engineering jobs exist, plus large purchases of equipment and materials suppliers both locally and across the U.S.
