The tunnels’ total length is more than 70km, in addition to nearly 140km of sewerage links and a number of main pumping stations. 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.
Dubai Municipality director general Hussain Nasser Lootah said that the expected cost of designing, implementing and operating the project for 100 years is about AED12bn (£2.27bn). The project’s implementation will take four years and will be in two phases.
Lootah said this project vital and strategic as its completion in late 2020 will result in removal of more than 121 sewage pumping stations spread across the city. The deep tunnels will have a depth of 25m to 90m below ground level. He said that it will spare Dubai sewage problems, maintenance works, and other issues for 100 years to come.
Traditional sewage system with pumping stations and main lines usually requires multiple maintenance and construction works within a period ranging between five and 20 years, said Lootah. The new system will ensure a lower cost and long-term solution for sewage problems in the city.
"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 Parsons Group president Mark Walsh.
Jaafar Halawi, first deputy director of parsons and parsons director in the Middle East & North Africa (MENA) for industrial projects, added: "We are glad to work on this key project and we are committed to providing the best solutions and successful ways of implementation."
