City of Indianapolis Deep Tunnel System. Two other advantages of DTSS are: It does not need to be continuously upgraded and expanded; Recognised as an outstanding engineering innovation, the DTSS project received the Institution of Engineers Singapore Prestigious Engineering Achievement Award and the ASEAN Outstanding Engineering Achievement Award in 2005, as well as the International Water Associations Project Innovation Award in 2008. 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. The project Keller was awarded subcontract work for rock fissure grouting under Ed Zublin AG for the Deep Tunnel Sewerage System Phase 2 project in Singapore. + '?List={ListId}&ID={ItemId}'), Watch video "DTSS: Singapore's Used Water Superhighway" >>, Active, Beautiful, Clean Waters Programme. '/_layouts/15/docsetsend.aspx' The Press-in Method has been adopted for the shaft construction*1 project for Singapore's Deep Tunnel Sewerage System (DTSS). Phase 1, completed in 2008, involved building 48 km of a deep tunnel system, including 60 km of link sewers and two 5-km-long deep-sea outfall pipes. 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. Monitoring was still in progress at the time of writing and will continue for three years. PUB. To put that in perspective, that's the equivalent of more than 43 football fields end to end. Yue Choong Kog, Transboundary Urban Water: The Case Study of Singapore and Malaysia, in Understanding and Managing Urban Water in Transition, et al. //]]> Two tiltmeters were installed on each column, one to detect movement in longitudinal direction of the railway and the other in the transverse direction. A one-pass lining solution is being installed for the first time in the Middle East on the Doha South Sewer Infrastructure Project (Contract MTS-01), a deep tunnel sewer system developed by Ashghal (Public Works Authority) in the State of Qatar. The Deep Tunnel Sewerage System (DTSS) is aimed at providing a robust and efficient means of catering to Singapore's used-water needs. Tan, Lee and Tan, Clean, Green and Blue, 189.20. The biogas is then conveyed to the IWMF to improve the thermal efficiency of the incineration plant, thereby boosting electricity production. The Deep Tunnel Sewerage System utilises large, deep tunnels to convey used water to centralised water reclamation plants for further treatment. When the entire DTSS is completed, existing intermediate pumping stations and conventional Water Reclamation Plants(WRPs) will be phased out, freeing up land. Deep Tunnel System, 2003 (Map) The $4 billion Tunnel and Reservoir Plan (TARP), better known as "The Deep Tunnel," is the Metropolitan Water Reclamation District of Greater Chicago's answer to water pollution and sewer backup problems in 52 municipalities in Cook County . The main challenges of this project include undercrossing Jurong River, expressways AYE and PIE, sea, cable tunnels underneath the seabed , live North-East Line MRT tunnel and CCL6 tunnels which are undergoing construction, etc. One of the most ambitious wastewater management programs in the world, the $3.65 billion DTSS will allow Singapore to accommodate an expected population increase from 4.5 million to 5.5 million, enable . We use cookies to ensure that we give you the best experience on our website. The clean-up of Singapore River and Kallang Basin took place largely between 1977 and 1987. Wastewater that accumulates in the Deep Tunnel is pumped to the surface and treated at Jones Island sewage treatment plant. Aused water superhighway for the future,the Deep Tunnel Sewerage System (DTSS) is a cost-efficient and sustainable solution conceived by PUB to meet Singapores long-term needs for used water collection, treatment, reclamation and disposal. Under this project some 48km of tunnels of diameters between 3.3m to 6m will be constructed. (Call no. 19 Work on . press release. '/_layouts/15/Hold.aspx' Minister for the Environment and Water Resources Masagos Zulkifli officiated the launch of the DTSS Phase 2 tunnel boring machine on 4 April 2019. The treated used water is further purified into ultra-clean, high-grade reclaimed water called NEWater or discharged to the sea through outfalls. The Deep Tunnel Sewerage System (DTSS) is a cost-efficient and sustainable solution conceived by the Public Utilities Board (PUB) to meet Singapore's long-term needs for used-water collection, treatment, reclamation and disposal. DTSS2 is the second phase of this project, comprising an approximately 30-km long South Tunnel, a 10-km long Industrial Tunnel, 60-km of Link Sewers and a new Water Reclamation Plant integrated with a NEWater facility. SINGAPORE - The Deep Tunnel Sewerage System (DTSS), conceived more than two decades ago by Singapore's national water agency PUB, is a superhighway for used water that is a lifeline for a small . The Main Trunk Sewer (MTS) is a major element of the Doha South Sewage Infrastructure Project. The system will involve the construction of two tunnels deep beneath the city, supported by 140km of link sewers and key pumping stations. View Image Gallery Ho Lee Construction was the sanitary and plumbing contractor for DTSS phase I. Yokogawa Engineering Asia supplied flow metres and transmitters to the Changi WRP, whilst ABB provided power solution and automation for the WRP. Any excess treated water is discharged into the sea through the outfall pipes.5Phase 1Work on Phase 1 of the DTSS project commenced in 2000 and was completed in 2008 at a cost of S$3.4 billion.6, This phase comprised a new WRP at Changi, two 5 km-long deep-sea outfall pipes, 60 km of link sewers, as well as 48 km of deep tunnel sewers made up of two sections, namely, the North Tunnel running between the Kranji and Changi WRPs, and the Spur Tunnel extending westward from the North Tunnel. 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. This was the first rock fissure grouting in Singapore and was carried out with the help of our Global Product Team and prior experience in Malaysia. Buried 300 feet underground and stretching 28.5 miles, Milwaukee's Deep Tunnel stormwater storage system is one of only a handful of its kind in the world. //>. In 2010, a NEWater factory was built atop the WRP. National Environment Agency, Singapore, PUB and NEA to Call Over S$5 Billion in Tenders for Tuas Nexus, press release, 9 July 2018.13. Singapores sewerage system previously consisted of six water reclamation plants, one sludge treatment works and 139 pumping stations located islandwide. Bridging the Gap: Meeting the World's Water and Environmental Resources Challenges April 2012 . var today = new Date(); PUB, Tuas Nexus, press release, accessed 23 October 2019.The information in this article is valid as atNovember 2019and correct as far as we are able to ascertain from our sources. which aims to create a network of 40km of deep tunnels and 60km of link sewers. With construction underway, this is the first project in Singapore to install HAT-type steel sheet piles using the Hard Ground Press-in Method*2. Milwaukee Metropolitan Sewerage District (MMSD) in Milwaukee, WI. ed., Quentin Grafton (Springer: Dordrecht, 2015), 586.15. The varying ground conditions along the tunnel alignment will also put the competency of the team to test. 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 collecting every drop of used water, DTSS allows for efficient, large-scale water recycling, thus ensuring the sustainability of NEWater. floatables, such as assorted jugs, bottles, bags, lumber scraps, and leaves) have accumulated . The deep tunnel sewerage system has long term sustainability and resilience of 3-node system. By freeing up land for other developments, DTSS has allowed Singapore to optimise the use of this scarce resource. document.getElementById("copyrightYear").innerHTML = today.getFullYear(); The freed-up land can then be used for other higher-value developments. (From National Archives of Singapore document no. + '?List={ListId}&ID={ItemId}'), /_layouts/15/images/sendOtherLoc.gif?rev=43, javascript:GoToPage('{SiteUrl}' + When completed, it will have a conveyance systemmade up of 60 kilometres of link sewers and 40 kilometres of deep tunnelsand the Tuas Water Reclamation Plant, known as Tuas WRP. Abstract The Deep Tunnel Sewerage System (DTSS) is aimed at providing a robust and efficient means of catering to Singapore's used-water needs.
