Dubai Municipality Starts Geotechnical Investigation for Dubai Strategic Sewer Tunnel Project
Dubai Municipality has actually started exploratory help a significant new sewer treatment system as part of the broader growth of a modern city infrastructure to suit continued populace growth.
The Dubai Strategic Drain Tunnel Project, for which Dubai Town has actually engaged Parsons Overseas Limited as engineering specialist, will certainly entail construction of more than 70km of passages supported by around 140 km of link sewage systems and key pumping terminals.
When completed in 2022, the project will certainly get rid of over 100 pump stations around the city that currently transfer sewer to therapy plants in Al Warsan and Jebel Ali.
Dubai Town, which has actually started a Geotechnical Investigation for the project, claims the key goals are to decrease the cost of dealing with sewer, lower carbon emissions through using gravity systems and decrease in power demand.
" The sewerage infrastructure is part of the necessary facilities of a modern city," said Eng. Hussain Nasser Lootah, Director General of Dubai Municipality.
" To fulfil the citys demands, Dubai has accepted an integrated strategy proposition to increase the existing sewage system and improve the plans for sewage disposal by incorporating land based sewage treatment and a deep tunnel sewage conveyance system."
Added Eng. Lootah: Since 2003, Dubai has actually experienced quick populace growth. In addition to a fast change in populace, there is an increase in domestic neighborhoods where blended use is picking up speed and residential areas are progressively accommodating business, public and mixed-use facilities.
" Thus, residential areas are affected significantly in terms of increasing thickness and overloading of existing infrastructure. The new sewerage system will offer the city for a minimum of the next 50 years. We wish to assure the local areas that they will certainly not experience any disturbances during the first exploration job."
A key part of the design process is to determine the existing ground parameters utilized to design the structural stability of the passages, shafts and link sewers.
The Drainage and Irrigation Division of Dubai District, led by Performing Director Mohammed Al Rayees, is waging the website investigation programme, of which Parsons has involved a company to pierce a series of 250 boreholes along the course of the brand-new sewage network. The DID anticipates this programme to take up to 9 months.
Throughout this field work phase, truck placed rotating rigs will move to locations along the proposed course of the passage and web link. The period of remain at any kind of solitary location will differ, depending upon boring deepness and in-situ screening needs.
Generally, however, drilling rigs are anticipated to remain at each location for 2 to five days. The gears will be geared up with exploration poles, pierce bits, excavation tools and different in-situ testing tools.
Varied ground conditions are anticipated to be experienced along the proposed passage and link drain alignment. It is vitally important to collect thorough subsurface information in order to create a precise and accurate ground version along the entire route which will certainly assist in the design procedure and selection of appropriate tunnelling tools and modern technology.
Upon completion of field work, the results of in-situ screening and research laboratory analysis will be reviewed to provide recommendations on proper construction approaches for the passages, link sewers and shaft excavations, and to provide ground criteria that will enable designers to create affordable styles.
The geotechnical examination will certainly consist of the preparation and execution of devastating and non-destructive techniques by utilizing conventional and specific drilling/testing devices. Samples of the soil and rock encountered will be recovered, and use for more evaluation.
