Subject Please contact the Library for further reading materials on the topic. The Deep Tunnel Sewerage System (DTSS) was conceptualised in the 1990s as a sustainable, cost-effective solution to meet Singapore's used water collection, treatment, reclamation and disposal needs in the long run. In the mid-1990s, the government conceptualised the Deep Tunnel Sewerage System (DTSS) as a more cost-effective and sustainable solution to meet Singapore's needs in the long run. Because this was within a railway protection zone, building codes required that the construction had to be monitored in real time. At one-third the size of conventional plants, the Changi Water Reclamation Plant is designed to be compact. The Deep Tunnel Sewerage System, which will be the conduit for all used water islandwide, will boost water recycling and free up space in land-scarce Singapore. By 2006, all of Phase I was completed and in operation. press release. The WRPs will treat and purify the sewage into clean, high-grade reclaimed water to be supplied under the brand name NEWater.

Released in 1992 by the then Ministry of MacPherson is one of the five sub-zones in the Geylang Planning Area. This is a cost-efficient and sustainable solution to meet Singapore's long-term needs for used water collection, treatment, reclamation and disposal. Around 30% of drinking water requirements are covered by . However, Singapores water supply faced an increased risk of contamination due to pipe damage owing to infrastructure degradation over time. // The completion of DTSS phase I has reduced the land previously used by the WRPs and intermediate pumping stations from 300ha to 190ha. They are connected to the existing sewerage system by the smaller link sewers that divert used water flows from the existing sewers into the deep tunnels. Another issue with the existing system was the large land area occupied by treatment plants and pumping stations. CH2M Hill and its joint venture partner Parsons Brinckerhoff conceptualised and managed the planning, design and construction of the DTSS phase I. Samsung Engineering and Construction was awarded the construction contract for a portion of the tunnels under DTSS phase I.Other contractors involved in Phase I included the TMCR Group, Ah Boon Civil Engineering and Building Contractor, Sembawang Engineers and Constructors, Penta Ocean Construcion Company, KTP Consultants and AKS Lining Systems. The implementation of the master plan meant that all of Singapore was served by a modern sanitation system by 1997.1However, Singapores water supply faced an increased risk of contamination due to pipe damage owing to infrastructure degradation over time. Spanning two phases over more than 20 years, Phase 1 was completed in 2008 while Phase 2 is due to be completed by 2025. By using new technology, this infrastructure will also take Singapore's sewage management into the next century.

Black & Veatch and AECOM signed the engineering contract for phase II of the DTSS in June 2014. The solution When the entire DTSS is completed, existing intermediate pumping stations and conventional Water Reclamation Plants(WRPs) will be phased out, freeing up land. to 32 ft. The tunnel boring machine (TBM) has been operating at a rate of 30 feet per hour since June 2007. Depth Underground: 275 to 340 ft. (From National Archives of Singapore document no. The electricity generated at the IWMF will fully power both facilities at Tuas Nexus, with excess electricity fed to the grid.12ImpactSingapores sewerage system previously consisted of six water reclamation plants, one sludge treatment works and 139 pumping stations located islandwide.13After the completion of DTSS Phase 1 in 2008, the Kim Chuan, Seletar and Bedok WRPs, as well as the Serangoon Sludge Treatment Works, were closed progressively.14 Once Phase 2 commences operations, the Ulu Pandan and Jurong WRPs will also be phased out.15 The numerous pumping stations used in the conventional conveyance system will be phased out too, since gravity is used in DTSS to transport used water to the WRPs.16The implementation of DTSS will eventually halve the land area occupied by used water infrastructure, which was 300 ha in the 1990s.
