The Dubai Electricity and Water Authority (Dewa) announced on Sunday that it has completed construction of the first stage of the Aquifer Storage and Reclamation (ASR) project for desalinated water and has started the operating and testing phase.

When the entire project is completed by 2025 as a strategic reserve, it will 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 water. drinking water and recover it in case of emergency.

This will secure the emirate with an additional source of strategic drinking water reserve of 50MIGD for 90 days in case of emergency while guaranteeing the quality of the stored water.

The ASR project uses clean solar energy to desalinate seawater using the latest reverse osmosis (RO) technologies. Excess water is stored in aquifers and reinjected into the water network when needed. The cost of this innovative integrated model is lower than the cost of traditional tanks and is a sustainable, ecological and economical solution.

Saeed Mohammed Al Tayer, Managing Director and CEO of Dewa, said the new project supports the utility provider’s efforts to increase Dubai’s storage capacity to 7212MIG in 2025 from the current storage capacity of 822MIG.
