Savener has developed the basic and detailed engineering for the Ghubrah III IWP reverse osmosis desalination plant, located in Muscat, Oman. This industrial complex, of high strategic value, aims to strengthen the country’s water security and supply more than 2.5 million people, representing approximately 20% of the contracted capacity of the national water network.
The plant has been designed to deliver maximum efficiency and operational reliability under extreme environmental conditions. All systems comply with the most stringent international standards, ensuring stable and sustainable long-term performance.
The water treatment system is centered around a robust pretreatment process using dissolved air flotation (DAF), followed by 32 multi-layer gravity filters (anthracite, sand, and gravel) capable of removing solids, algae, and suspended particles. This stage is critical for ensuring the efficiency of the reverse osmosis membranes, which perform the separation of dissolved salts.
The energy required for operating pressure is optimized through energy recovery systems, significantly reducing specific consumption (kWh/m³). Brine discharge is carried out via submarine outfalls designed for environmentally safe dispersion.
Seawater intake is handled by offshore structures connected to large-diameter pipelines, designed for continuous operation under harsh ocean conditions. The system has been designed with resilience and minimal maintenance criteria.
Savener has also designed the technical buildings housing process systems, electrical infrastructure, chemical systems, and control units. Specific solutions have been developed for each area, including HVAC installations, automation, and auxiliary systems.
The entire facility has been designed with a focus on modularity, advanced control, and simplified maintenance, incorporating: SCADA systems and distributed supervision, plate heat exchangers, variable-speed pumps, pressurization systems, full thermal insulation, among others. These elements ensure optimized operation and adaptability to varying load and demand scenarios.
The plant is scheduled to commence operations in the first quarter of 2027, establishing itself as a critical infrastructure asset in the national and regional water strategy.
Ghubrah III stands as a technical and industrial benchmark in water desalination, integrating advanced engineering, operational sustainability, and energy efficiency, in alignment with the Oman Vision 2040 objectives.
