The construction of the first stage of the Aquifer Storage and Recovery (ASR) project for desalinated water has been completed by Dubai Electricity and Water Authority (Dewa).
The ASR project can store up to 6,000 million imperial gallons of water once completed by 2025 as a strategic reserve, according to reports.
The project is the largest ASR of its kind in the world to store potable water and use it during an emergency. Now, Dubai will have an additional source of potable water strategic reserve of 50MIGD for 90 days during emergencies. It will also ensure the quality of the stored water.
Saeed Mohammed Al Tayer, managing director and CEO of Dewa, said that the new project supports Dewa’s efforts to increase the storage capacity of Dubai to reach 7212 MIG in 2025 when compared to the present storage capacity of 822 MIG.

“We support the vision of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai, to provide a state-of-the-art, integrated, and resilient infrastructure of electricity and water in Dubai according to the highest standards of availability, reliability, efficiency and safety. This helps to ensure meeting the rapidly growing demand for water across different areas in Dubai for all citizens, residents and visitors. Besides the ASR project, Dewa is working on a 120 MIG reservoir in Al Nakhali and another 60 MIG reservoir in Al Lusaily,” added Al Tayer.
With this project, Dubai’s sustainable production of water has gone up. The project uses clean solar power to desalinate seawater using the latest Reverse Osmosis (RO) technologies. Water which is in excess is stored in aquifers and pumped back into the water network when required. This integrated model costs less than the traditional reservoirs, while being sustainable and eco-friendly.
