Combined with the existing Jebel Ali Phase 1 sewage treatment works, the new facilities treat the equivalent of the sewage flow originating from a city of 3.35 million inhabitants. A project of this magnitude is unprecedented in the GCC region. All sewage water is treated up to Dubai’s strict irrigation water standards and allows the city to cut back the use of costly desalinated seawater for non-potable use by 700,000,000 litres per day through re-use applications such as irrigation. The second phase of the project was completed using 143,000m3 of reinforced concrete, 24,000 tons of reinforced steel, 2659 mechanical and engineering equipment and machinery, 700km of cables and 30km of pipes.
