Dubai Electricity and Water Authority (Dewa) on Sunday said it has completed construction of the first stage of the Aquifer Storage and Recovery (ASR) project for desalinated water and has started the operations and testing stage.

Upon completing the entire project by 2025 as a strategic reserve, it’ll be able to store up to 6,000 million imperial gallons of water, making it the largest ASR of its kind in the world to store potable water and retrieve it in case of an emergency.

This will secure the Emirate with an additional source of potable water strategic reserve of 50MIGD for 90 days in emergencies while ensuring the quality of the stored water.

The ASR project uses clean solar power to desalinate seawater using the latest Reverse Osmosis (RO) technologies. Excess water is stored in aquifers and pumped back into the water network when needed. The cost of this innovative integrated model is less than the cost of traditional reservoirs and is a sustainable, eco-friendly, economical solution.
