Singapore’s water agency, the Public Utilities Board (PUB), has selected a consortium led by Bejing Enterprises Water Group and United Engineers as the preferred bidder for the Changi II plant under PUB’s Newater marque.
The plant will reclaim secondary effluent to add 228,000 m³/d to the nation’s water supply. The plant will use microfiltration, ultrafiltration reversible, osmosis and ultraviolet disinfection.
The consortium will deliver the project under a 25-year design-build-own-operate (DBOO) arrangement at a first-year price of S$0.276/m³ (US$ 0.218/m³). The new plant is scheduled to be operational in 2016.
Black & Veatch is the owner’s engineer for the project.
The plant is the second Newater Plant at Changi and the third DBOO Newater project between PUB and the private sector. The previous two were the 145,345 m³/d Keppel- Seghers Ulu Pandan Newater Plant and the 228,000 m³d SembCorp Changi Newater Plant. Along with the other Newater projects located at Bedok and Kranji, Newater currently provides 30% of Singapore’s demand. That share is now set to increase to 55%.
