CANNON Artes breaks ground on seawater desalination plant for 3-GW power project in Saudi Arabia
- The project will deliver 34,000 m³/d of treated water, marking a major milestone in sustainable water and energy management
CANNON Artes has been awarded the contract for the engineering and supply of a large-scale seawater desalination treatment plant for the Hajr Expansion CCGT IPP Project, a 3-GW combined-cycle, gas-fired power plant located in Saudi Arabia’s Eastern Province.

The desalination plant forms part of a $2.6-B combined-cycle power project developed by a joint venture between ACWA Power, the Saudi Electricity Company, and Haji Abdullah Alireza & Co., with Orascom Construction and Técnicas Reunidas as the EPC contractors.
The project, recently assigned and now entering its detailed design phase, represents a significant technological achievement in industrial water treatment and desalination under extremely challenging conditions.
The new facility will treat 34,000 m³/d of high-salinity seawater, producing demineralized water for steam generation, potable water for plant consumption, and service water for various utilities. Designed to ensure optimal performance and long-term reliability, the system exceeds local regulatory requirements while reinforcing CANNON Artes’ commitment to environmental sustainability and resource efficiency.
