Abu dhabi super tunnel

National Geographic Abu Dhabi has been successful in becoming a favourite with millions of Arab households throughout the Middle East.

September 7, - The construction of the Abu Dhabi Deep Sewer Tunnel, one of the deepest gravity tunnels in the world, as explored in a documentary by National Geographic. STEP oversaw the construction of a tunnel about 40 kilometres long in order to collect the waste waters of the island and mainland of Abu Dhabi by means of gravity, and direct them to a treatment plant in Al Wathba. Salini Impregilo took part in the project, working on two of the three lots T and T awarded to contractors. It drilled a tunnel of 25 kilometres with an excavation diameter of about seven metres, and 10 access shafts with depths varying between 40 and 80 metres. The Group used sophisticated, mechanised excavation technology never previously deployed in Abu Dhabi. The project was particularly complex from a technical and organisational point of view because it involved the simultaneous use of five Tunnel Boring Machines TBMs at earth pressure.

Herrenknecht designed and commissioned the segment production plant as part of the project. Image courtesy of Herrenknecht Formwork Technology. The construction activities started in with the prequalification process commencing earlier in August The project, which is scheduled for completion in , is being carried out with an investment of AED 5. The current project forms a crucial part of Plan Abu Dhabi , which is a comprehensive plan of developing Abu Dhabi to accommodate the increasing population in the city, which is anticipated to reach three million by The project is expected to supply 15 cusec of greywater for irrigation. As of February , 33km of the overall 41km of the tunnel has been tunnelled. The tunnel will start at a depth of 27m underground and reach a depth of m towards Al Wathba. The sewage water from the connecting sewers will be directed to the deep tunnel through gravity, where an underground pumping station will lift the sewage to the Al Wathba Independent Sewage Treatment Plants ISPTs for final treatment. The connecting sewers or link sewers will overall enable the city to do away with 35 existing pumping stations which are on the verge of finishing their useful life. Construction works involve excavation using tunnel boring machines and casing of the tunnel with precast concrete sections. The hydraulic tunnel and the access shafts are being lined with a special membrane to protect the concrete sections.

This film follows a team of engineers in Abu Dhabi they race to build a massive sewer system right beneath the city streets, as the current network has reached its bursting point. Abu Dhabi's population has exploded in recent decades. But beneath the city trouble is brewing. Abu Dhabi's sewer network - built thirty years ago to service the needs of a small town - has reached bursting point. It's running beyond capacity and can no longer cope with the growth above. This film follows a team of larger than life engineers and construction workers locked in a race against time to build a replacement sewer beneath the city. Dallas Campbell hosts the
