Sheikh Hazza bin Zayed visits largest reserve of desalinated water in Liwa
The reserve now holds more than 26 million m3 of water
Below the Liwa desert lies the largest reserve of high-quality desalinated water secured in a network of 315 recovery wells recently built at a cost of Dh1.61 billion.
The reserve now holds more than 26 million cubic metre (m3) of water (equivalent to 5.6 billion imperial gallons) that can bolster drinking water supply when needed.
The project, implemented by Abu Dhabi Water and Electricity was commended by Sheikh Hazza bin Zayed, Deputy Chairman of Abu Dhabi Executive Council during a recent field visit accompanied by officials.
The wells are fed by one of UAE’s longest water pipeline networks, which runs the water from Shuweihat desalination plant at a rate of 7 million imperial gallons (approximately 32,000 m3) / day over 27 months.
The reserve, which has at its core an infiltration and recovery system sitting atop a natural fresh water underground aquifer, was first investigated in 2002.
The project addresses Abu Dhabi’s water security and its resilience through the recharge of groundwater aquifers with high-quality desalinated water, which cannot be stored above ground due to contamination and other factors.
The desalinated water is piped from the coast to create the secure, underground reserve system and was accomplished by a multi-national and multi-disciplinary team of experts from the Environment Agency Abu Dhabi, Abu Dhabi Transmission & Despatch Company (Transco), ADWEA, RSB, the independent regulatory body for Abu Dhabi’s water and electricity sector, GIZ International, Rainer Consultancy and ACC-Posco JV.
Whenever needed, water from the wells, lying up to 80 metres below ground, can be used to recover supplies at any time, thus ensuring continuous water supply for Abu Dhabi city and Al Dhafra region and securing the reserve for future generations.
