Infrastructure Dubai’s Dewa gets 2 bids for $410m Hassyan water project By Pramod Kumar May 26, 2023 Wam Dewa aims to produce 100% of desalinated water by a mix of clean energy and waste heat by 2030 Utility provider Dubai Electricity and Water Authority (Dewa) received two bids for its 120 million gallons per day Hassyan independent water producer project. Bids were submitted from Saudi’s Acwa Power and UAE’s Abu Dhabi National Energy Company (Taqa). Acwa Power sent the lowest water levelised tariff of $0.389 per cubic metre for the base proposal of 120 mgd, and $0.365 per cubic metre for the alternative proposal of 180 mgd for the AED1.5 billion ($410 million) Hassyan seawater reverse osmosis plant. The desalination project is Dewa’s first independent water project. The Dubai-listed company aims to select the preferred bidder during the second quarter of 2023. The 120 mgd water project, based on reverse osmosis technology, consists of two blocks of 60 mgd each. The first block is scheduled to start operations in October 2025, while the second will commence in April 2026. “We are building water production plants based on reverse osmosis, which requires less energy than multi-stage flash distillation plants, making it a more sustainable choice for water desalination,” said CEO Saeed Mohammed Al Tayer. Dewa aims to produce 100 percent of desalinated water by a mix of clean energy and waste heat by 2030, he added.
