Dubai Municipality is advancing the Resilient Future Flow Outfall Project (DS411), a major subsea infrastructure initiative designed to strengthen the emirate’s resilience to rising groundwater levels and support sustainable urban expansion. The announcement was made by Fahd Al Awadhi, Director of Drainage System at Dubai Municipality, as part of the broader Tasreef Stormwater Program.
The project involves the construction of a 4.0-kilometre subsea pipeline with a diameter of two metres and a discharge capacity of nine cubic metres per second. It provides a sustainable solution for managing groundwater levels, which are rising by nearly 20 centimetres each year, posing increasing risks to key infrastructure. The system will also serve as a secure emergency outlet for recycled water from the Jebel Ali Sewage Treatment Plant when required.
“This project is critical to protecting airports, logistics hubs, residential communities, and industrial zones across Jebel Ali,” Al Awadhi said. “By mitigating flood risks and safeguarding vital assets, it supports safe and sustainable urban expansion in one of Dubai’s most dynamic growth corridors.”

In addition to its strategic importance, the Resilient Future Flow Outfall Project demonstrates Dubai Municipality’s commitment to engineering innovation and environmental protection. The works incorporate advanced techniques such as the Float & Sink method for subsea installation, GPS-enabled dredging, pneumatic string testing, and state-of-the-art diffuser technologies. These measures ensure technical excellence, operational reliability, and full compliance with UAE environmental standards.
Al Awadhi emphasized that the project is more than an engineering milestone; it represents a strategic investment in Dubai’s future, reflecting the city’s vision of world-class and resilient infrastructure designed to withstand the pressures of urbanization and climate change.
The DS411 project is part of Tasreef, Dubai Municipality’s AED 30 billion long-term stormwater drainage development program scheduled for completion by 2033. Tasreef aims to expand coverage to all areas of the emirate and increase the drainage network’s capacity by 700 per cent, enabling it to manage more than 20 million cubic metres of water per day. The program also seeks to reduce the construction and operating costs of pumping stations by 20 per cent through the use of deep tunnel systems with flow capacities of up to four cubic metres per second.
Earlier phases of Tasreef have already enhanced stormwater and groundwater management infrastructure across key areas such as Al Maktoum City, Expo City Dubai, and the Airport District.
