Abu Dhabi Water and Electricity Authority (Adwea) announced that it will establish the world's largest sewage network tunnel system in the UAE's capital city. The system will cover the island and mainland of the city of Abu Dhabi, with an estimated cost of about Dh4 billion, and is scheduled for completion within five years to meet the growing demand resulting from the massive urban expansion of the capital.
"Adwea is in the process of constructing the world's largest drainage system, starting from Abu Dhabi Corniche Road, passing through Airport Road, until it reaches the new sewage treatment plant at Al Wathba," Shaikh Diab Bin Zayed Al Nahyan, Adwea's chairman, told the media yesterday.
The announcement came during the authority's revealing of its two and five-year strategic plans, which are designed to meet the gross demand for 10,600 megawatts (MW) of electricity and 848 million imperial gallons per day (MIGD) forecast by 2012.
