Jurong Island Desalination Plant (Singapore)


A reverse osmosis (RO) system for the Jurong Island Desalination Plant (JIDP) with a capacity of 135,000 m3/d


JIDP was constructed under the Design, Build, Own, and Operate model by a joint venture company formed by the Tuas Power-ST Engineering consortium for a 25-year period.


The winning consortium awarded IDE the RO system with capacity of 137,000 m3/d

  • Pre-fabricated modular design

  • Size & durability

    The first large-scale pre-engineered modular plant. The entire plant was fabricated in pre-assembled modules and tested in the production facility before being shipped to the site.

  • Design challenges

    Overcame difficult seawater conditions, including very high levels of Total Suspended Solids (TSS), high levels of organics, and numerous algae events, as well as significant daily tidal variations and conflicting currents that reverse seawater temperature and characteristics every six months.
