Dubai Strategic Sewerage Tunnels – Dubai, United Arab Emirates (UAE)

Design And Urban Planning, Program/Construction Management (PM/CM)

The Dubai Strategic Sewerage Tunnel Project by the Dubai Municipality (DM) entails 75km of two deep wastewater tunnels, deep pump stations, and 220km of link sewers that convert Dubai from a lift station system to a full gravity system. The project eliminated more than 100 pump stations throughout the city that transferred wastewater to the Warsan and Jebel Ali Sewage Treatment Plants (WSTP and JSTP). The new system reduced the overall cost of treating wastewater, reduced carbon emissions, decreased power consumption, and supports Dubai’s population growth.

Project Scope And Environmental Impact

Our scope included updates to the master plan flow forecasts, feasibility studies, preliminary design, tender preparation, program management for the detailed design consultants and design-build contractors, and construction supervision of the primary tunnels and terminal pumping stations. We also conducted studies to optimize the current functionality of WSTP and JSTP as part of synergizing the existing facility to the tunnel system in the future. Other studies include stormwater relief management, sewerage system policy, financial modeling, environmental impact assessment, and system resilience through risk assessments. We were also responsible for implementing an innovative project management information system (PMIS) with building information management (BIM) capabilities and conducted public engagement plans for the project.

During this project, we ensured our design minimized traffic disruptions and inconvenience to the public by careful selection of shaft sites. In addition, the deep tunnel design largely mitigated surface disruptions to the environment, compared with traditional open-cut construction techniques.
