CH2M to deliver Tuas Water Reclamation Plant in Singapore

Singapore-based national water agency PUB has appointed CH2M to deliver the Tuas Water Reclamation Plant (WRP).

The plant will be co-located with the Integrated Waste Management Facility (IWMF) to be developed by the National Environment Agency (NEA) and is a key component of PUB’s Deep Tunnel Sewerage System Phase 2 project (DTSS2).

Together the plant and IWMF will increase the water-energy-waste nexus.

CH2M state and local Governments president Greg McIntyre said: “By co-locating the Tuas WRP with the IWMF, the project will continue PUB’s history of innovation and industry leadership.

“We also look forward to leveraging our shared values on health and safety to “raise the bar” throughout the entire delivery of Tuas WRP and into operations.”

Tuas WRP, which will employ new treatment processes to reduce energy consumption, will be capable of treating an average dry weather flow of 650 Mega-litres/day (MLD) of domestic and 150 MLD of non-domestic used water.

It will also increase biogas production for the generation of electricity and convert used water into NEWater and industrial water for re-use by industry.

Tuas WRP is slated for completion in 2025.

DTSS has been conceived by PUB to meet long-term needs for used water collection, treatment, reclamation and disposal in Singapore.

Upon completion, it will have 120km of link sewers and more than 100km of deep tunnels to convey used water by gravity to water reclamation plants located at coastal areas.

It will also streamline the used water network with centralised collection and treatment points – Changi WRP (CWRP) in the east, Kranji WRP in the north and Tuas WRP in the west of Singapore.
