Milestone achievement in Dubai’s wastewater treatment

Dubai’s wastewater treatment capacity has reached a milestone with the Dubai Municipality completing the second phase of the expansion of the Jebel Ali Sewage Treatment Plant at a cost of Dh1.3 billion (SGD 479 million).

With a capacity of 375,000 cubic metres of water for this stage, the combined capacity of Warsan and Jebel Ali plants will go up to about 1 million cubic metres with the possibility of future expansion of three more stages, the civic body said on Wednesday.

Dawoud Al Hajiri, director General of Dubai Municipality, said in a press release that the current expansion of Jebel Ali plant is one of the important infrastructure projects for the coming years to keep pace with Dubai’s comprehensive growth in all areas.

“This expansion will cover the Expo and other areas of development and can accommodate the continued and future population growth with high efficiency. It will also support the strategy of the provision and preparedness of infrastructure.

Noting that the combined capacity of our plants in Warsan and Jebel Ali has reached one million cubic metres of wastewater per day, Al Hajiri said: “We have also reduced the cost of treating this wastewater to make this the world’s lowest expansion.”

How this will help irrigation
This expansion is characterised with a 25 per cent reduction in energy consumption and produces about 232 billion cubic metres of irrigation water that is compliant with international standards.

Al Hajiri said this supports the municipality’s plan to plant trees in the city in a big way as this water would be enough to irrigate 6,250 hectares of cultivated land.

The project also handles 21,900 tons of solid wastes rich in nutrients that make them suitable fertilisers with high international standards and can be used as biofuels.

The project was completed taking 10 million working hours and using 143,000 cubic metres of reinforced concrete, 24,000 tons of reinforced steel, 2,659 mechanical and engineering equipment and machineries, 700km of cables and 30km of pipes.

Al Hajiri added: “What is unique about this project is the participation of a young UAE cadre of 13 engineers, including three females.”

Fahad Al Awadi, director of Drainage and Irrigation Department and Project Manager, pointed out that the first part of the project deals with water treatment and the second with the treatment of solid materials.

“The civil works included drilling, pouring concrete and insulation, providing structural plans and delivery of materials, along with electromechanical works and installation of equipment,” he said

Al Awadi said the project will absorb the excess flow from the areas of Expo and other areas and will cover the existing urban projects and future projects in the emirate. It also diverts the proportion of the load from Warsan to Jebel Ali station.
