Dubai has awarded the consultancy contract for its strategic sewer project to implement feasibility studies. When started, this infrastructure project will mean a spate of opportunities for construction professionals for at least the next five years when it is due to complete.
Earlier this year Dubai was ranked as one of the top five model Cities of the Future by the International Real Estate Federation. This is due in part to its urban planning, infrastructure, sustainability criteria and economic diversification - which make Dubai a great city to live or work in.
This new deep sewerage tunnel system will add to many of those categories. At a cost of 12 billion (AED)/3 billion Euro, it will add a network of deep sewer tunnels in the areas of Deira and Bur Dubai.
The Deep Tunnels
The network of tunnels will eventually cover the whole of the Emirate. There will be two pumping stations: a 90m deep one at Jebel Ali and a 35m deep one at Al Warsan. The diameter of the tunnels will start at about 3.5m increasing to 5 -6m. Micro tunnel technology will be necessary to facilitate the construction of the shafts. The 70 km of tunnels will be between 25 and 90m below the ground.
Two or More Phases
The project will be carried out in two stages. Phase 1 will cover the section Deira to the pumping station at Al Warsan; Phase 2 will see sewage from Bur Dubai reach the pumping station at Jebel Ali. Extra phases maybe added to service new development areas.
In line with Dubai's sustainability principles, the system will use gravity to collect the sewerage. With the need for electricity at these points withdrawn, 121 pumping stations will be replaced making the collection of sewerage more cost effective. Closing the pumping stations will also cut down on maintenance costs. A win-win situation. Another bonus will be the estimated cut in carbon emissions by as much as 30 percent.
Looking ahead, the Dubai Municipality expect the tunnels to last a good 100 years.
Don't Miss Out
This is an important infrastructure project that will require serious contenders for the roles of quantity surveyors, engineers, tunnelling experts, project managers and the like.
