The Dubai Municipality has announced that the second phase in the expansion of the Jebel Ali Sewage Treatment Plant has been completed at an estimated cost of Dh1.3 billion ($354 million).
The project, with a water treatment capacity of 375,000 cu m, takes the combined capacity of Warsan and Jebel Ali plants to about one million cu m with the possibility for further expansion.
Dawoud Al Hajri, the director-general of Dubai Municipality said: "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."
"We have also reduced the cost of treating the wastewater to make this the world's lowest expansion," he added.
The expansion is characterized by a 25 per cent reduction in energy consumption and produces about 232 billion cu m of irrigation water compliant with international standards and supports the 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.
"What is unique about this project is the participation of a young cadre of 13 engineers, including three women," noted Al Hajri.
Fahad Al Awadhi, the director of Drainage and Irrigation Department and also the project manager, said the first part of the project deals with water treatment and the second with the treatment of solid materials.
It has been completed with 10 million working hours and using 143,000 cu m of reinforced concrete, 24,000 tons of reinforced steel, 2,659 mechanical and engineering equipment and machinery, 700 km of cables and 30 km of pipes, said the top official.
The project handles 21,900 tonnes of solid waste rich in nutrients that make them suitable fertilizers with high international standards and can be used as biofuels, he added.
