Dubai Municipality has signed a contract awarding Parsons Corporation the project to build a Deep Tunnel Sewerage System at a total cost of AED 12bn ($3.26bn).
Following its completion in late 2020, the project will remove the need for more than 121 sewage pumping stations spread across the city, saving large amounts of energy.
The deep tunnels will have a depth of 25-90 meters below the Earth’s surface and have a total length of 70kms. Two tunnels will be dug, one in Deira to transfer sewage flows to the treatment plant in Al Warsan, and the second in Bur Dubai to transfer sewage to a treatment plant in Jebel Ali.
Additional phases could also be implemented in order to serve new development zones or link the two regions of Deira and Bur Dubai.
Eng. Hussain Nasser Lootah, Director General of Dubai Municipality, said the deep-sewage system will reduce maintenance costs, cut electricity consumed by the system by 30 percent and cut the need for tanks to transfer sewage through the city to treatment plants.
The services provided by Parsons include feasibility studies, preliminary design, preparation of IPO, then project management in detailed design stages as well as the implementation and supervision of the implementation of tunnels and the lift station.
“The project is of a great importance for the Dubai Municipality and for its role in developing the city of Dubai as a global city,” said Mark Walsh, President of Parsons Group, adding that “Parsons made multiple successes in the management of the most developed and difficult sewage projects worldwide. We look forward to providing our services for the Dubai Municipality.”
