The Electricity and Water Authority (EWA) of the Kingdom of Bahrain has announced an international tender for the engineering, procurement, and construction (EPC) of the new Hawar seawater reverse osmosis (SWRO) desalination plant.
The project, titled “Construction works for New Hawar SWRO Desalination Plant,” was launched on 1 October 2025, with a bid submission deadline of 30 November 2025. The EPC contract will run for two years.
Designed to produce 1 million imperial gallons per day (MIGD) of potable water, the facility will link with two related contracts: Tender No. 4621/2025/3200 for offshore seawater intake and outfall systems, and Tender No. 4623/2025/3200 for ground storage tanks and water transmission pumps.
EWA’s eligibility criteria require bidders to demonstrate experience in designing, constructing, and commissioning at least two SWRO desalination plants of 2 MIGD capacity or more over the past decade, each with at least two years of operational performance.
Located about 26 kilometers southeast of Ras Al Bar, the Hawar Islands comprise 16 desert islands and islets. The largest, Hawar Island, already hosts an eco-resort and is poised to benefit from the enhanced water infrastructure.
The Hawar SWRO tender forms part of EWA’s wider strategy to strengthen Bahrain’s energy and water security. In recent months, EWA has also announced major projects, including the Sitra Independent Water and Power Production Plant (IWPP) and the Hidd Independent Water Production Plant (IWP).
His Excellency Eng. Kamal bin Ahmed Mohammed, President of EWA, noted that seven global developers, including TAQA, ACWA Power, GIC, JERA, KEPCO, Sumitomo, and CEMC-China Datang consortium, have been pre-qualified for Bahrain’s IWPP projects.
He emphasized the authority’s commitment to leveraging advanced reverse osmosis (RO) technology and high-efficiency systems to deliver reliable power and water supply. The Sitra IWPP will begin initial commercial operations in 2028 and reach full operation by 2029, while the Hidd project and a solar-powered electricity and water production facility are also underway.
Together, these initiatives highlight Bahrain’s strategic drive toward sustainable energy and water resilience through innovation, global partnerships, and renewable integration.
