The implementation of the entire Deep Tunnel Sewerage System will allow PUB to reduce the overall land footprint of the used water system across Singapore by half, freeing up to 150ha of land – nearly twice the size of the Botanic Gardens.
Described as a"superhighway" for used water, the infrastructure project will boost water recycling and improve long-term water sustainability in Singapore, the national water agency said in a media release.
"Spanning multiple tunnelling and construction contracts, the DTSS Phase 2 project involved over 5,000 workers at the peak of its construction works." Construction of the first phase of the system, with tunnels spanning 48km through the eastern half of Singapore, was completed in 2008. Phase 2 began in 2014 and is slated for completion in 2026.
More than 130 pumping stations across the country were needed to bring used water to these plants for treatment before the treated water was discharged to the sea.Over two phases, the DTSS comprises a 206km-long network of deep tunnels and link sewers that will convey used water via gravity to three centralised water reclamation plants in Changi, Kranji and Tuas, PUB said.
"The tunnelling works had to be carried out by five different contractors, using pioneering construction methods and smart technologies for safe and smooth operations," the agency said.Construction of Phase 2 also saw the implementation of new features that will allow authorities to ensure the integrity of deep tunnels and maintain them more easily.
