DEWA Reports 90% Progress on First Phase of Hassyan Desalination Project

Dubai Electricity and Water Authority (DEWA) has announced that construction of the first phase of the seawater desalination plant at the Hassyan complex is nearly complete, with work reaching around 90 percent.

Saeed Mohammed Al Tayer, MD and CEO of DEWA, reviewed progress at the site and confirmed that all phases of the project are on track for completion in the first quarter of 2027. With total investments of approximately AED3.377 billion, the Hassyan facility is among the world’s largest seawater reverse-osmosis (RO) desalination projects and marks DEWA’s first independent water producer (IWP) initiative.

Al Tayer said the project reflects the vision of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President, Prime Minister, and Ruler of Dubai, to develop advanced and integrated energy and water infrastructure that supports the emirate’s rapid growth and rising demand. He noted that the plant plays a key role in strengthening water security and advancing sustainable development, while supporting DEWA’s strategy to expand desalinated water production capacity.

During his visit, Al Tayer toured several sections of the facility and received detailed briefings from Hassyan Water Company A on construction progress. He highlighted the project’s importance to Dubai’s smart water infrastructure and its alignment with the Integrated Water Resources Management Strategy 2030.

Al Tayer also emphasized DEWA’s shift toward reverse-osmosis technology, which consumes less energy than traditional multi-stage distillation methods and offers a more environmentally sustainable solution. By 2030, DEWA plans to add 240 million imperial gallons per day to its desalination capacity using RO technology.

The inspection was attended by Mohammad Abunayyan, Chairman of ACWA Power, along with senior DEWA executives, members of the board of Hassyan Water Company A, and a number of engineers and officials involved in the project.
