$3.4bn deep tunnel sewerage system for Dubai
The new deep tunnel system makes use of gravity for the collection of sewage and will replace more than 121 sewage pumping stations in the next five years
The emirate of Dubai will get a new deep tunnel sewerage system costing $3.4bn in the next five years to replace more than 121 sewage pumping stations.
The new deep tunnel system makes use of gravity for the collection of sewage, Hussain Nasser Lootah, director-general of Dubai Municipality said.
According to him, it will significantly reduce the running-cost of the sewage system, as it will replace the pumping stations that required electricity to run and periodic maintenance. The project will help in turning Dubai into a sustainable and environment-friendly city. The tunnels will also help reduce carbon emissions by 30 per cent.
Following the approval of His Highness Shaikh Mohammad Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, to implement the new project, Dubai Municipality signed a contract awarding Parsons Corporation the project on Sunday.
Lootah said the first phases of the project will be ready in five years, while the entire project is expected to be handed over in seven years.
“This plan is 50 years ahead, and will be able to accommodate any future growth in Dubai. Due to its large size, it is also very easy to connect any new projects to it. ” he said, adding that this unique system has been implemented in many big cities in the world.
The tunnel system will replace more than 121 sewage pumping stations with deep tunnels that will range between 25-90 metres below the earth’s surface.
“Imagine a 90 metre tunnel, that is almost the size of a 30-floor building,” he said.
