Dubai's AED2.5 billion stormwater expansion aims to bolster resilience and sustainability

Dubai Municipality has recently pushed forward with a significant expansion of the city’s stormwater infrastructure. They’ve awarded five new contracts under Phase Two of the Tasreef Programme, worth AED2.5 billion. This set of projects targets 30 key areas across the emirate, covering around 430 million square meters. The goal, as per Zawya and municipal reports, is to support an estimated three million residents by the year 2040.

This latest batch includes three construction contracts and two design commissions. The municipality has selected global firms like DeTech Contracting and China State Construction Engineering Corporation to carry out these projects, with specialized consultants brought in for planning and engineering. These initiatives are part of a broader AED30 billion initiative, the Tasreef programme, that the Dubai Municipality describes as a long-term plan to overhaul deep-tunnel and surface drainage systems throughout the city.

Dubai Municipality explained that the Phase Two activities build upon earlier efforts within the same programme. Back in April 2025, they awarded four contracts totalling AED1.439 billion, aimed at developing, rehabilitating, and expanding drainage networks in neighborhoods like Nad Al Hamar, Al Garhoud, Al Quoz, Zabeel, and Jumeirah. Industry observers see these awards as a phased approach, designed to quickly increase capacity while keeping a close eye on engineering standards.

The scope for Phase Two includes a mix of large-diameter tunnel boring, network expansions, along with new pumping stations and storage facilities. One of the projects involves constructing a main tunnel up to four meters across, connecting different parts of the city, like Sheikh Mohammed bin Zayed Road and Al Yalayis Road, to the main deep-tunnel drainage system. Another project covers an integrated system spanning over 27 kilometers, between Sheikh Zayed Road and Al Jamayel Road, featuring sophisticated tunnels and supporting conduits to serve transport routes and industrial zones.

Another important aspect centers on boosting inland flood resilience. This involves building a drainage tunnel, establishing a modern pumping station along Dubai–Al Ain Road and Sheikh Zayed bin Hamdan Al Nahyan Street, and creating a strategic stormwater collection lake designed to handle water discharge more effectively. Design contracts also include linking areas like Al Marmoom and Saih Al Salam to the main network via Al Qudra Road, an effort aimed at supporting both tourism and residential growth, all while protecting local ecological assets.

The municipality stresses that these projects aim to enhance hydraulic capacity, increase operational flexibility, and reduce surface water flooding, which is vital for sustainable urban development. Marwan Ahmed bin Ghalita, Dubai Municipality’s Director-General, pointed out, “The Tasreef Programme is a practical example of long-term strategic planning that Dubai Municipality has adopted for managing the city’s infrastructure and operations. Our goal is to develop an integrated stormwater system that boosts city resilience, conserves resources, and safeguards residents and visitors’ quality of life, helping position Dubai as one of the best places in the world to live and work.”

Adel Al Marzouqi, CEO of the Waste and Sewerage Agency, highlighted how these projects contribute to resilience and ongoing service. He mentioned, “The new projects under Phase Two of Tasreef really mark an advanced step toward making Dubai’s stormwater drainage more efficient and sustainable. They will boost network capacity, especially in key areas, and prepare the infrastructure to face climate challenges, all while ensuring continuous service, safety, and quality of life improvements.”

Public statements and press releases from the municipality frame Tasreef as a strategic answer to the uncertainties of climate change alongside rapid urban growth. The planned works aim to minimize flood risks for roads, commercial districts, and residential neighborhoods. In addition, Dubai South has separately entered a AED150 million partnership with Dubai Municipality to connect its residential zone to the deep-tunnel network via Expo Road, as municipal documents reveal. This deal aims to reduce surface runoff impacts and protect public assets within the Dubai South master plan.

For industry insiders focused on climate technology and infrastructure, a few key points stand out. First, the focus on deep-tunnel conveyance, large-diameter bored tunnels, and pumped storage shows that the emphasis remains on centralized, engineered systems rather than solely green infrastructure. Second, the scale of the investments and the linkages to transport corridors reveal an intent not just to fix local flood issues, but to safeguard economic activities too. And third, the planning around ecological sites like Al Marmoom and Saih Al Salam indicates an effort to balance development with habitat preservation.

Analysts note that execution risks will largely depend on how well coordination is managed across complex urban corridors, especially with utility relocations and integration with existing drainage networks. Contractors will need to carefully plan sequencing to avoid disrupting major highways like Sheikh Mohammed bin Zayed Road and Sheikh Zayed Road. Meanwhile, the supply chains for tunnel boring equipment, pumps, and other infrastructure components will be put to the test, particularly since multiple contracts are rolling out simultaneously.

Dubai Municipality sees this programme as a multi-decade infrastructure project linked to the Dubai 2040 Urban Master Plan and the country’s climate neutrality targets. Briefings suggest that the current awards are part of a staged approach, designed to expand capacity rapidly, but also allow for design tweaks and improvements along the way.

As the projects develop, ongoing monitoring will focus on sticking to timelines, controlling costs, and safeguarding the environment, especially where the developments intersect with protected or sensitive ecosystems. For the UAE’s climate tech sector, Tasreef opens up opportunities too, ranging from smart sensor systems inside tunnels and pump stations to nature-based solutions that complement surface drainage efforts. It’s quite a comprehensive approach, really.
