Notably, in August 2022, Doosan Enerbility secured a $640 million contract with ACWA Power for the Shuaibah 3 IWP in Saudi Arabia, designed to produce 600,000 tons of water daily, reflecting strong demand for large-scale desalination projects in the Middle East.
The desalination plant operation & maintenance (O&M) services market is increasingly driven by digital twin technology, real-time monitoring, and predictive maintenance. A 2025 study from ACS Publications highlights that digital twins allow operators to simulate plant operations, optimize energy consumption, and prevent membrane fouling a critical challenge in desalination. Leading companies like IDE Technologies demonstrate the impact of these technologies, achieving 98% plant availability over two decades through proactive operational strategies and low-maintenance designs. This trend illustrates how digital solutions are transforming O&M into a value-generating function, improving plant reliability and longevity.
Governments and utilities are increasingly adopting performance-based PPP models for desalination projects, linking O&M responsibility to long-term contracts. For instance, the V.O. Chidambaranar Port Authority in India issued a 5 MLD desalination plant project on a DBFOT basis, requiring private entities to manage long-term operations. Similarly, the Shuqaiq 3 plant in Saudi Arabia has achieved global recognition for its energy-efficient design and long-term PPP model, which incentivizes operational excellence. Such frameworks are accelerating the adoption of specialized O&M services, emphasizing efficiency, reliability, and contractual accountability.
Energy consumption is a critical factor in desalination O&M. The Saudi Water Authority (SWA) has achieved a 10.9% reduction in specific energy consumption since 2020 by prioritizing Reverse Osmosis (RO) technology and implementing energy-saving strategies. Companies like VA TECH WABAG are securing long-term O&M contracts, such as the 7-year SWRO Nemmeli Desalination Plant project in Chennai, emphasizing performance, efficiency, and sustainable water supply. The integration of energy-efficient practices and sustainability measures is redefining O&M as a strategic, high-value service.
The market presents strong opportunities for service providers offering integrated operation, maintenance, spare parts management, and consulting. Digital solutions for predictive maintenance, coupled with performance-based PPPs, create demand for long-term, specialized O&M contracts.
