PROJECTS CEREmOny maRkS yanbu 2 mED COmPlETiOn The completion ceremony for the Yanbu Phase 2 Expansion seawater desalination plant was held on 19 December 2012 by Doosan Heavy Industries & Construction in Jeddah, Saudi Arabia. The plant features the world's largest multi-effect distillation (MED) unit with a production capacity of 15 MIGD (68,190 m3/d). With more than twice the capacity of the 8.5 MIGD (38,600 m3/d) Fujairah 2 desalination plant in the UAE, will be sufficient to meet the daily requirements of more than 200,000 people. Starting the engineer/procure/construct project from June 2011, Doosan completed the Yanbu plant in 18 months. The treated water produced by the plant will be supplied to the Medina region. Present at the completion ceremony were Prince Abdualaziz bin Majed bin Abdulaziz Al Saud, governor of Medina; Abdullah bin Abdul Rahman Al Hussein, the minister of water and electricity; Dr Abdulrahman bin Mohammed Al-Ibrahim, governor of the Saline Water Conversion Corporation; Keysun Han, president and COO of Doosan; and Seokwon Yun, CEO of Doosan's Water Business Group. Following the ceremony, a contract signing ceremony was held for the Yanbu Phase 3 Seawater Desalination Plant, the contract for which Doosan was notified of being awarded in November 2012. mORE mOvES On mOnTEREy DESalinaTiOn PROPOSalS The final report on the choice of seawater desalination plants proposed for the Monterey Peninsula in California was presented to the Monterey Peninsula Regional Water Authority on 18 December 2012 by its consultant, Separation Processes Inc (SPI). However, events have moved on since SPI finished accumulating data in the middle of October 2012, with one of the three proposed projects actually changing hands. According to SPI, the proposal by California American Water (Cal Am) is the most advanced timewise. Cal Am disputes the report's suggestion that it would also be the most expensive and local interpretation that they are increasing the size of the proposed plant. Cal Am's Catherine Bowie told D&WR: "We are about 8 months into a 22-month review process being conducted by the California Public Utilities Commission (CPUC). Last week we presented new demand factors that were not included in our original application." "Essentially, we are supplying updated information to CPUC that they will consider in determining the size of the plant," Bowie explained. "I think it is more accurate to say that we have revised the demand figures and that the CPUC will include this information in their review process." The SPI report says that CPUC is "aggressively pushing forward implementation" of the Cal Am project. A "Scoping Report" will be prepared describing the project and the project alternatives that will be considered in a draft environmental impact report scheduled for circulation by 1 July 2013. While Cal Am is still aiming for a 2016 start-up to beat the deadline for reduction of abstractions from the Carmel river, neither of the alternatives will commence operations before 2018, the consultant's report says. The Deepwater Desal proposal, based at Moss Landing and the only one looking to expand the initial plant at a later date to supply other regions, won the backing of the Salinas City Council on 18 December 2012 "to explore the purchase of water and wholesale power". It would use existing infrastructure at Moss Landing power station. The third project, originally known as the People's Moss Landing Water Desal Project, now has a different owner. Donald Lew, managing partner of investment company JDL Development LLC, told a meeting of Pacific Grove City Council that JDL had taken over the project and renamed it the Regional Desalinization Project at Moss Landing Commercial Park. Ghana DESalinaTiOn bEGun by abEnGOa The Yanbu Phase 2 Expansion MED plant. | 26 | Desalination & Water Reuse | February-March 2013 Construction of the Nungua seawater reverse-osmosis (SWRO) plant in Ghana, the first large desalination plant in West Africa, is now under way. Spanish contractor Abengoa announced the start of the US$ 125 million project on 19 November 2013. The SWRO plant will have a capacity of 60,000 m3/d. Abengoa will be responsible for design and construction, as well as subsequent maintenance and operation for a 25-year period. The work is expected to take 24 months and will create some 400 direct and indirect jobs. Revenues from water sales are forecast to exceed US$ 1,300 million during this time. The plant will enable drinking water to be supplied to more than 500,000 residents in the towns of Teshie, Nungua and Tema. This project will increase Abengoa's installed water desalination capacity to nearly 1.2 million m3/d.
