Dubai Electricity and Water Authority (DEWA), signed a 30-year water purchaser agreement with Saudi Arabia’s ACWA Power for phase 1 of the Hassyan sea water desalination project using solar power. The project is part of DEWA’s efforts to increase its water desalination capacity to 730 MIGD by 2030, from 490 MIGD at present.

The project aligns with Dubai’s unparalleled economic growth and the Emirate’s thriving construction sector. This complements the Dubai 2040 Urban Master Plan, addresses the substantial population growth, and meets the steadily increasing demand for water in domestic, commercial, and other consumer sectors.

The agreement was signed by HE Saeed Mohammed Al Tayer, MD & CEO of DEWA; and Mr. Mohammad Abunayyan, Chairman and Founder of ACWA Power. Officials from both entities were present.

Last August, DEWA announced ACWA Power as the ‘Preferred Bidder’ for the construction and operation of the 180 Million Imperial Gallon per Day (MIGD) Sea Water Reverse Osmosis Hassyan Phase 1 Independent Water Producer (IWP) project, with an investment of AED 3.357 billion (USD 914 million).

The allocated land area for the project is 252,300 square metres. DEWA achieved a world record by receiving the lowest bid of 0.36536 USD/m³ of desalinated water.

This project is the largest of its kind in the world for water production based on Sea Water Reverse Osmosis (SWRO) technology using solar energy. It is DEWA’s first Independent Water Producer (IWP) model project. The water desalination capacity in Dubai is currently 490 MIGD. This capacity will increase to 670 MIGD in 2026 with the completion of this project.
