Finalists Announced For Singapore’s 5th Desalination Plant

Keppel Infrastructure, Sembcorp Utilities, Tuas Power and YTL Power International are the four finalists shortlisted by PUB (Singapore’s water authority) for a desalination project on Jurong Island.

The proposals were for the design, build, ownership and operation of a plant that can provide 137,000 m3 per day by 2020. Each proposal sets out a tariff structure and terms and conditions for supply and purchase of desalinated water under a 25-year water purchase agreement.

Keppel was awarded the Marina East project at the beginning of the year which has the same capacity as the proposed Jurong Island.

Singapore currently has two desalination plants in operation, SingSpring and Tuaspring, which operate with a combined capacity of 100 mgd. Both plants use reverse osmosis for its desalination, which uses 3.5kWh/m3.

One of PUB’s goal is to halve the desalination energy used in the future. This will no doubt be a feature that the finalists have factored into their designs.

The Tuas plant is testing and planning to scale up an electrodeionisation facility that will produce 38,000m3/day.

Here is a diagram of how the other existing plant SingSpring operates. It has a pre-treatment process where suspended particles are removed before RO.
