Ministry of the Environment and Water Resources, Deep Tunnel Sewerage System (DTSS), press release, 20 January 2001 (From National Archives of Singapore document no. The deep tunnel works entirely bygravity, eliminating the need for pumping stations, and thus the risks of used water overflows. Spanning two phases over more than 20 years, Phase 1 was completed in 2008 while Phase 2 is due to be completed by 2025. 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.

This was the rst rock ssure grouting in Singapore and was carried out with the help of our Global Product Team and prior experience in Malaysia. 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. The S$3.4 billion Deep Tunnel Sewerage System (DTSS) is an efficient and cost-efficient solution to meet Singapore's long-term needs for used water collection, treatment, reclamation and disposal. Navin Sregantan, PUB Starts Second Phase of DTSS with S$2.3B of Work Contracted Out, Business Times, 20 November 2017.9. The 2 tunnels diameter start at about 3.5 m and end at about 5 to 6 m.

View Image Gallery When the entire DTSS is completed, existing intermediate pumping stations and conventional Water Reclamation Plants(WRPs) will be phased out, freeing up land. The varying ground conditions along the tunnel alignment will also put the competency of the team to test. By freeing up land for other developments, DTSS has allowed Singapore to optimise the use of this scarce resource. Facebook Twitter Instagram. The challenge During the project, the client . (From National Archives of Singapore document no. The treated used water is then reclaimed and further purified into NEWater, with excess effluent discharged to the sea in an environmentally responsible manner. To address these problems, the government sought a sustainable long-term alternative that would allow Singapore to meet its growing needs without a need for continual expansion and upgrading. For example, the Deep Tunnel Sewerage System (DTSS) of Singapore, Kuching Wastewater Management System of Malaysia . DTSS uses deep tunnel sewers to convey used water by gravity to centralised water reclamation plants (WRPs) located at the coastal areas. The whole of Singapore will be served by the DTSS when Phase 2 is complete by 2025. Under this project some 48km of tunnels of diameters between 3.3m to 6m will be constructed. 2.8 kilometers of sewage tunnel for Phase 2 of the Deep Tunnel Sewerage System in Singapore. "The Deep Tunnel Sewerage System is an integral part of Singapore's water management as it allows every drop of used water to be collected, treated, and further purified," said PUB's Chief Executive, Khoo Teng Chye, upon accepting the Water Project of the Year award at the Global Water Awards in Zurich, Switzerland, in April, 2009.

The biogas is then conveyed to the IWMF to improve the thermal efficiency of the incineration plant, thereby boosting electricity production. DTSS is a key part of our long-term used water system which comprises a network of link sewers leading to two major tunnels (Phase 1 & 2) criss-crossing Singapore with three large WRPs at the northern (Kranji), eastern (Changi) and western (Tuas) ends of Singapore, as well as outfall pipes. The project challenges are: One of the challenges of Milwaukee's Deep Tunnel is that over the past 18 years heavy trash (i.e. The Milwaukee RTC system supervises a sewerage network comprised of an intercepting deep tunnel over 20 miles long that intercepts both combined and sanitary sewer systems (Schultz et al., 2001). If you continue to use this site we will assume that you are happy with it. The Deep Tunnel Sewerage System (DTSS) was conceptualised in the 1990s as a sustainable, cost-effective solution to meet Singapores used water collection, treatment, reclamation and disposal needs in the long run. The Main Trunk Sewer (MTS) is a major element of the Doha South Sewage Infrastructure Project. [CDATA[ //]]> Although now heralded as a success, the project was not without its challenges. Construction on the first phase was completed in 2008 and the second phase is scheduled to begin in 2016, with completion by 2022. Collectively called Tuas Nexus, both facilities will allow Singapore to harness potential synergies in the water-energy-waste nexus. The two screen shots at right (columns and engineering drawing) show how MultiMon overlays a representation of the site with color-coded data boxes. To meet Singapore's needs, the Singapore government put in place an S$3.65 billion Deep Tunnel Sewerage System (DTSS). The system was conceived by Singapore's Public Utilities Board (PUB) as a cost-saving, sustainable solution to meet Singapore's future needs for used water collection, treatment, reclamation and disposal. The ALCOSAN deep tunnel system (DTS) is a gravity sewer; however, during normal operations it runs in a constant surcharged state. The electricity generated at the IWMF will fully power both facilities at Tuas Nexus, with excess electricity fed to the grid.
