Contractor will install 230km of pipes in Mirdiff under US $34 million contract.
Arabtec will install a new US $34 million (AED126 million) sewerage and drainage scheme in the Dubai suburb of Mirdiff - the largest such contract ever to be awarded by Dubai Municipality.
Around 600 construction workers will be employed on the job which will run to April 2007.
It will ensure the safe disposal of wastewater by connecting nearly 3000 residential plots to the existing sewerage collection network.
And it will replace the current system which is based on septic tanks that must be emptied regularly by the Municipality.Arabtec plans to use a combination of open cut and micro-tunnelling techniques to install the new network.
“We will be doing some micro tunnelling and pipe-jacking as instructed by Dubai Municipality,” said Amin Shahin, head of the drainage division at Arabtec.
He added: “We are installing both sewerage and stormwater networks independently.
“As the network completes, we will start working on the house connections,” he added.
Under the contract, Arabtec will install 1.6km of GRP, 6km of asbestos fibre cement pipe, and the remainder in uPVC.The scope of work will also include providing a surface water drainage network, house connections, inspection chambers, road crossings and connection of the new system to the existing system.
The existing sewerage system drains to Main Pumping Station ‘K’, which ultimately ends up in the main Dubai sewage treatment plant.
Currently Dubai Municipality transports some 40 000 m3 of wastewater to the main treatment plant every day.Over 230 km of pipes ranging in diameter from 160 mm to 1000 mm and nearly 8000 manholes and chambers will be constructed within the two year contract duration.
The project is a part of Dubai Municipality’s five-year strategic plan with the objective of setting up sewerage and storm water networks to cover all the urban areas within the emirate of Dubai.
Preliminary works have already started on the project.
