With a projected total cost of approximately $8 billion (AED 30 billion) the undertaking will be one of the emirates largest infrastructure projects.  The project is designed to increase the capacity of Dubai’s rainwater drainage system by 700% and will cover all areas of the Emirate state.

The ‘Tasreef’ project was approved in the presence of Sheikh Maktoum bin Mohammed bin Rashid Al Maktoum, First Deputy Ruler of Dubai, and Deputy Prime Minister and Minister of Finance of the UAE; and Sheikh Ahmed bin Mohammed bin Rashid Al Maktoum, Second Deputy Ruler of Dubai.

Sheikh Mohammed bin Rashid Al Maktoum stressed that the continued development of Dubai’s sustainable infrastructure is critical to its growth and prosperity.

The initiative aims to create a drainage infrastructure that is advanced, safe, flexible, and ready to face future challenges.

The ‘Tasreef’ project is a continuation of drainage projects launched by Dubai in 2019, covering the Expo Dubai area, Al Maktoum International Airport City, and Jebel Ali.

Once complete the rainwater drainage capacity through the tunnels will reach 20 million cubic metres per day, with a flow capacity of 230 cubic metres per second, making it the largest rainwater collection project in a single system in the region.

To construct the tunnels the project will utilise the latest Tunnel Boring Machines (TBM), predicted to be the largest of their kind in the Middle East.
