PUB announces design consultant for Tuas WRP

PUB announces design consultant for Tuas WRP

14 March 2017 , , 0

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

DTSS Phase 2 will extend the existing deep tunnel system to collect wastewater from the western and southern parts of Singapore.

The system will be made up of 60 km of link sewers and 40 km of deep tunnels. Works will also include construction of the Tuas WRP.

The appointment of CH2M Hill Singapore was announced last month 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.

PUB DTSS Phase 2 Director Yong Wei Hin – who spoke to Trenchless International about the project in 2016 – 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.”

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.

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

It will be co-located with an incineration facility to harness the potential synergies of the water-energy-waste nexus, making it more efficient and greener.
