In late December 2020, the Public Utilities Board (PUB) announced that it would award a SGD 237 million (USD 180 million) contract to the China State Construction Engineering (CSCE) branch in Singapore. It is the sixth major construction contract awarded by PUB for the Tuas Water Reclamation Plant, which is part of the Deep Tunnel Sewerage System Phase 2. It will allow CSCE to construct two industrial liquids modules to be used for large-volume treatment of industrial used water.
The modules will be used to treat industrial used water channeled to the plant via deep sewer tunnels, which will then be further purified into industrial water and sent back to industries for reuse. The two modules allow for better solids separation while using less space and fewer steps compared with conventional systems. They are collectively expected to treat up to 150,000 cubic meters of industrial used water per day. This would further improve Singapore’s water sustainability by boosting PUB’s capacity to reclaim and recycle water, adding on to the Changi Water Reclamation Plant, which was completed in 2008.
