SingSpring owns and operates Singapore’s first and only large-scale seawater desalination plant which commenced commercial operations in December 2005. With a capacity of supplying up to 136,380 m³ of desalinated potable water per day, the plant is an essential facility capable of meeting approximately 10% of Singapore’s current water needs.

The desalination plant, which is located in Tuas, Singapore, utilises advanced, cost and energy-efficient reverse osmosis ("RO") technology, as part of its water desalination process. It was the largest membrane-based seawater desalination plant in the world at the time of its completion.

In April 2003, SingSpring and Singapore’s national water agency, the Public Utilities Board (“PUB”), entered into a long term 20-year Water Purchase Agreement (“WPA”) commencing in December 2005 and expiring in December 2025. Under the WPA, Capacity Payments are payable throughout the term of the WPA and do not vary with the volume of water supplied by the SingSpring Plant. SingSpring appointed Hyflux Engineering Pte. Ltd. in October 2003 as the operation and maintenance operator for a 20-year term.

SingSpring ensures that the quality of desalinated water produced meets all the requirements under the WPA. SingSpring is committed to make available 100% of the plant’s capacity to the PUB for the term of the WPA.

SingSpring anticipates that the RO technology will remain viable in the long term, and taken together with the continuous efforts and investments required to operate and maintain the SingSpring plant, expects the plant to be able to supply desalinated water beyond the term of the WPA.
