Indian contractor wins desalination contract in Saudi Arabia

5 January 2026

India-headquartered VA Tech Wabag has won an engineering, procurement, construction and commissioning (EPCC) contract for a brackish water reverse osmosis plant in Saudi Arabia.

The 50,000 cubic-metres-a-day (cm/d) facility in Al-Jouf is being procured by Saudi Arabia’s main producer of desalinated water, Saudi Water Authority (SWA), formerly Saline Water Conversion Company.

The Bombay Stock Exchange-listed company confirmed in a statement that it will design, supply, construct and commission the plant over 14 months, with a construction start date yet to be announced. The total cost of the project is estimated at $120m.

According to Wabag, the facility will treat raw water supplied from borewell fields that contain rare elements. This will require robust pre-treatment using ceramic membrane technology, followed by micron cartridge filtration and reverse osmosis.

SWA is currently working with Wabag on other desalination projects. In 2025, it awarded Wabag a $272m contract to build a 300,000 cm/d seawater reverse osmosis plant in Yanbu, Saudi Arabia.

Construction is scheduled to start in April and take three years to complete.

SWA is the world’s largest producer of desalinated water, managing more than 40 desalination plants with a combined capacity exceeding 11 million cm/d.

Plants utilising older, more energy-intensive techniques, such as multi-stage flash technology, account for the majority of current capacity.
