Singapore consumes about 440 million gallons of water per day, and this will almost double by 2065. To meet the projected increase in used water, Singapore’s Public Utilities Board (PUB) will be redeveloping Kranji Water Reclamation Plant (WRP) and Kranji NEWater Factory.
The treatment capacities for these key infrastructure will be increased and they are expected to be ready around 2035. Together, they will bolster NEWater, an ultra-clean and high-grade water, production to augment water supply and strengthen Singapore’s water resilience against growing water demand and the impact of climate change.
The new Kranji WRP will adopt advanced technologies including Membrane Bio-Reactor (MBR) and Thermal Hydrolysis Process (THP) to achieve better treatment and land-use efficiencies. MBR technology uses a smaller footprint than conventional treatment, while producing a higher quality effluent that can shortcut the existing NEWater treatment process.
The new Kranji WRP will be connected to the Deep Tunnel Sewerage System (DTSS) and completes the three-node DTSS system for water reclamation, with Changi WRP in the East and Tuas WRP in the West. All three WRPs will be co-located with NEWater factories.
The existing Kranji WRP was constructed in the 1980s. It serves developments in northern Singapore, including Woodlands, Sungei Kadut and Choa Chu Kang. Kranji WRP treats used water for further reclamation at the co-located Kranji NEWater Factory to produce NEWater or for discharge to the sea.
