SINGAPORE – CH2M Hill Singapore Pte has been appointed by water agency PUB as the Detailed Design Consultant for the Tuas Water Reclamation Plant (WRP), a key component of the Deep Tunnel Sewerage System (DTSS) Phase 2.

CH2M Hill Singapore was appointed following a pre-qualification and tender exercise in 2016.

Over the next two years, the firm will develop the detailed design of Tuas WRP and subsequently supervise the construction and commissioning of the plant.

The construction of Tuas WRP is expected to commence 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 650,000 m3/day module and then further purified to NEWater, while industrial used water will be treated at a separate 150,000 m3/day module and sent back to industries for reuse.

With an initial total treatment capacity of 800,000 m3/day Tuas WRP will be the largest MBR facility in the world, but with a 30% more compact footprint compared to conventional plants.

Tuas WRP will also feature an integrated NEWater factory and will be co-located with an incineration plant.

Yong Wei Hin, Director, DTSS Phase 2, PUB, said: “DTSS Phase 2 continues to leverage advanced technologies and detailed planning to enhance Singapore’s used water management system and ensure water resilience and sustainability for generations to come. With a separate network for the collection and treatment of industrial used water, the Tuas WRP enables PUB to not only meet the growing water needs of the industrial sector, but also ensures the continued reliability of NEWater.”
