Treated water reservoir for Dubai?
Plans to supplement water portfolio could include treated wastewater
A recent joint venture between Dubai Municipality and construction company Hitachi Plant Technologies is to conduct a feasibility study to look into the potential of an underground treated water reservoir for Dubai, the Khaleej Times has reported.
With diminishing groundwater representing a significant threat to Dubai’s future energy resources, the pilot project could see the 182 million cubic metres of water generated annually in the emirate used for replenishing groundwater, eventually creating an underground reservoir.
Mohammed Abukaff, environmental expert with Dubai Municipality has said that about 70 per cent of the waste water is already being reused after treatment, with the rest diffused into the sea following purification. “Our attempt is to make 100 per cent use of the waste water,” he added.
The pilot project will use membrane bioreactor technology developed by Hitachi Plant Technologies to biologically remove the nutrients in the wastewater, in an attempt to make treated sewage safe for industrial use. Phase two of the project will investigate the possibility of using the treated water in aquifer recharge.
