Over the next two years, CH2M Hill Singapore will develop the detailed design of Tuas WRP and then supervise the construction and commissioning of the plant.
The construction of Tuas WRP is expected to start in the second half of 2018 and will feature multiple construction tenders for civil, mechanical and electrical engineering works as well as equipment providers for various plant components.
Unlike conventional WRPs, the advanced Tuas WRP will be receiving used water flows from the western part of Singapore via two separate deep tunnels – a tunnel to convey domestic used water and another to convey high-strength industrial used water. It will also use membrane bioreactor (MBR) technology to treat both used water sources and to higher standards. Domestic used water will be treated at a 650 000m3/day module and then further purified to NEWater, while industrial used water will be treated at a separate 150 000m3/day module and sent back to industries for reuse.
With an initial total treatment capacity of 800 000m3/day, Tuas WRP will be the largest MBR facility in the world.
