Singapore's innovative sewage project wins global award
Singapore's deep tunnel sewerage system (DTSS), a superhighway for used water management, has won an international innovation award from the International Water
Association (IWA), Malaysian news agency Bernama reported.
The international award was the first won by the innovative project which was conceived by PUB, Singapore's national water agency, as a sustainable solution to the
republic's long-term used water management needs.
PUB said the DTSS, which was slated for completion by the end of this year at a cost of S$3.65 billion ($2.5 billion), comprised a 48-km-long deep tunnel that stretched from
Kranji to Changi, a centralised used water treatment plant at Changi, a network of link sewers and a deep sea outfall.
PUB started building the DTSS in 2000 to cater to Singapore's increasing population and expanding economy.
When completed, used water collected from homes and industries will be channelled through the deep tunnel to the Changi Water Reclamation Plant where it is treated to international standards before being discharged into the sea or sent to the NEWater factory to be bottled.
