Dubai Water Main Rehabilitation

Project context

Dubai Municipality required rehabilitation of a 35-year-old steel potable water main running beneath major arterial roadways. The conveyed water was sourced from desalination plants and required full sanitary compliance. Existing pressure rating had to be preserved post-rehabilitation, and the project had to be completed during the cooler winter months to minimize impact on residential water supply.

Our solution

Huatao supplied the dedicated water-supply variant of our Flexible Reinforced Tube, with PE coating compliant with potable water sanitary standards. Pull-in installation through manhole entries preserved existing road surface intact. Wall thickness of 7-8 mm provided structural reinforcement while retaining pressure capacity. The sealed annular hose construction ensured zero leakage post-curing.

Outcomes

• 1,850 meters of DN400–DN800 water main rehabilitated trenchlessly
• 6-week project window matched seasonal water-demand low period
• Full pressure rating retention verified through hydrostatic testing
• Sanitary compliance certified for potable water service
• Zero excavation on arterial roadways
• Service interruption limited to nighttime windows by segment
