Singapore - Tuas

Tuas

The Tuas Water Reclamation Plant (WRP) in Singapore, which is under construction by national water agency PUB, is integrating two thermal hydrolysis process (THP) trains.

The solution is an excellent match for PUB’s drive towards sustainable water management, having been selected based on technical merit, sustainability, and cost-effectiveness. Thermal hydrolysis from Cambi will enhance biogas production and reduce the sludge volume to be incinerated at the adjacent Integrated Waste Management Facility (IWMF).

PUB is a statutory board under Singapore's Ministry of Sustainability and the Environment (MSE). It is one of the world's leading and most innovative water utilities, managing Singapore's water supply, water catchment, and used water in an integrated way. When completed, Tuas WRP will be receiving up to 800,000 cubic meters daily of domestic and industrial used water. PUB is building Tuas WRP as part of the Deep Tunnel Sewerage System (DTSS) Phase 2 project for efficient and sustainable conveyance of used water to the plants for treatment and recycling. 

Cambi will supply THP technology to CES_SALCON-SDC JV, a joint venture between CES_SALCON Pte Ltd and CES_SDC Pte Ltd, both part of the Chip Eng Seng Corporation (CES). CES_SDC Pte Ltd is currently constructing Tuas WRP’s biosolids building, digesters and greasy waste receiving facility.

Tuas WRP will be the second PUB used water facility equipped with Cambi THP after Jurong WRP in 2015. The THP trains at Tuas WRP are scheduled to progressively start operating from 2026.
