Hyflux was named the preferred bidder for the Tuas II Desalination Plant in Singapore, which will be the country's largest seawater desalination plant. The $890 million project involves designing, building, owning, and operating a 318,500 cubic meters per day seawater reverse osmosis desalination plant over a 25-year concession period. Hyflux's role includes undertaking 100% of the engineering, procurement, and construction work as well as 100% of the operations and maintenance through its subsidiaries. The desalination plant is expected to begin operations in 2013 and will help ensure Singapore's water security by providing approximately 13% of the country's water demand.

Driven by Our Innovative Membrane Technology
 Second largest ultrafiltration
membrane installation after Magtaa
Desalination Plant in Algeria, the
world’s largest membrane-based
desalination plant
 Proprietary Kristal ultrafiltration
membranes designed and developed
in-house
1) provide high quality water for reverse
osmosis pre-treatment
2) enhance performance and extend
lifespan of reverse osmosis membranes
3) consume less chemicals and energy
 First ultrafiltration membrane to
achieve NSF certification for removal
of cryptosporidium

 Currently, only 47% of total population have access to improved water source.
 By end of 2014, as part of the roadmap to achieve the Millennium Development Goals (MDG) set by
United Nations, the Government wants to increase household access to an improved drinking water
source to ~70% of total population.
 One of Water Resources Development Targets for 2010 – 2014: To increase the raw water infrastructure
service capacity by 43.4 m3/s (~3,740MLD).

 Australia faces immense challenges in water management due to water scarcity and the impact of ever-
changing climate. Cities and towns need to secure their water supplies and reduce reliance on traditional
rainfall dependent water sources.
 Investment in large desalination and recycled water schemes is likely to continue across Australia.
 Industrial users are also likely to continue to switch from the use of municipal water source to the use of
privately-owned, on-site WTPs using rainfall independent water source.
