Dubai Storm Water Tunnel Lining Segments

The objective of the Deep Tunnel Storm Water System project by Dubai Municipality’s Drainage Projects Department, is to collect, store and convey groundwater and rainwater runoff from almost 490 km² (about 40%) of Dubai’s urban area. This includes Dubai South, Al Maktoum International Airport, EXPO 2020 Dubai, and other adjacent localities. The Deep Tunnel Storm Water System forms part of Dubai’s vision for a smart and sustainable city. It will provide the infrastructure needed to serve Dubai’s growing residential and business communities, to be able to cope with increasing urbanisation that causes rising ground water levels and the rare rain events. The economic impact of rain events, though rare, is significant for Dubai and hence a robust infrastructure by way of the deep tunnel system is being implemented. To support the tunnel construction, PORRSix Construct Joint Venture has set up a precast segment factory to produce the approximately 43,000 tunnel segments.
