Energy Recovery Secures Key Role in Saudi Arabia’s Vision 2030 Desalination Project
Energy Recovery (Nasdaq: ERII), a global provider of energy-efficient technologies that support affordable water production and lower emissions, has been awarded a contract to supply its proprietary PX® Pressure Exchanger® energy recovery devices for a major new seawater reverse osmosis (SWRO) desalination project in Saudi Arabia. The large-scale facility is being developed as part of the Kingdom’s ambitious Vision 2030 strategy and is expected to provide reliable drinking water to nearly one million people across the Mecca, Al-Baha, and Asir regions.
The project highlights Saudi Arabia’s ongoing efforts to strengthen water security and expand sustainable infrastructure in response to population growth, economic diversification, and increasing demand for freshwater resources. Once operational, the desalination plant will become one of the flagship water infrastructure developments in the country, helping ensure a stable supply of potable water in one of the world’s most water-scarce regions.
Supporting Water Security in an Arid Nation
Saudi Arabia faces significant water challenges due to its geographic and climatic conditions. The Kingdom has no permanent rivers or natural lakes and receives very limited annual rainfall, making conventional freshwater resources extremely scarce. As a result, desalination has become the backbone of the nation’s water supply system.
Today, more than 70 percent of Saudi Arabia’s drinking water originates from desalination facilities. Consequently, investments in advanced and energy-efficient desalination technologies are essential for maintaining long-term water security and supporting the nation’s economic development plans.
The new desalination project is particularly significant because it will serve the western and southwestern regions of the Kingdom, including Mecca, one of the most important cultural and religious centers in the world. Mecca welcomes millions of visitors and pilgrims each year, creating substantial seasonal demand for water and other infrastructure services.
Earlier this year alone, more than 1.5 million pilgrims traveled to Saudi Arabia to participate in the annual Hajj pilgrimage. Such large gatherings place considerable pressure on regional water systems, emphasizing the need for resilient and reliable water infrastructure capable of supporting both local residents and international visitors.
By increasing desalination capacity and integrating advanced energy-saving technologies, Saudi Arabia aims to ensure uninterrupted access to clean water while reducing the environmental footprint associated with water production.
Energy Recovery’s PX Technology
Under the new contract, Energy Recovery will provide its industry-leading PX Pressure Exchanger devices for use in the plant’s reverse osmosis process.
Reverse osmosis desalination involves forcing seawater through semi-permeable membranes under extremely high pressure to separate salts and impurities from water. While highly effective, this process can also be energy intensive and costly if advanced energy recovery systems are not utilized.
Energy Recovery’s PX technology addresses this challenge by capturing and reusing hydraulic energy that would otherwise be lost during the desalination process. The devices transfer pressure energy from the concentrated brine stream directly to incoming seawater, significantly reducing the amount of energy required by high-pressure pumps.
The company’s PX devices are capable of achieving efficiency levels of up to 99 percent, making them among the most effective energy recovery technologies available in the global desalination market.
According to Energy Recovery, deployment of PX technology can reduce energy consumption in seawater reverse osmosis facilities by as much as 60 percent. Lower energy usage translates into reduced operating costs, improved plant economics, and lower greenhouse gas emissions.
Another major advantage of the technology is its reliability. The PX device contains only a single moving part and is designed for a service life of approximately 30 years. This durability reduces maintenance requirements and contributes to long-term operational stability for large desalination facilities.
Aligning with Vision 2030
Saudi Arabia’s Vision 2030 initiative is focused on transforming the national economy through diversification, infrastructure development, sustainability initiatives, and improved quality of life.
Water infrastructure has emerged as one of the key pillars of the strategy. The Kingdom continues to invest heavily in desalination plants, water transmission systems, wastewater reuse projects, and advanced technologies that improve efficiency and sustainability.
The new desalination facility represents another step toward achieving these objectives by ensuring dependable access to freshwater while minimizing energy intensity.
Rodney Clemente, Senior Vice President of Water at Energy Recovery, emphasized the importance of the project and the company’s long-standing relationship with the region.
“Saudi Arabia continues to advance an impressive portfolio of water infrastructure to meet rising demand, and this contract reflects the trust the region places in Energy Recovery’s technology,” Clemente said.
He also noted that while project timelines across the Middle East continue to evolve due to changing market conditions and customer requirements, Saudi Arabia remains committed to steadily executing its long-term water security plans under Vision 2030.
Energy Recovery has been an active participant in the Middle Eastern desalination market for many years, supplying its technology to numerous major facilities across the region. The latest award further strengthens the company’s position as a strategic partner in helping governments and utilities address increasing water demand through energy-efficient solutions.
Growing Global Demand for Sustainable Desalination
The contract also reflects broader global trends in water infrastructure development. Rising populations, urbanization, industrial expansion, and climate change are increasing pressure on freshwater resources worldwide.
Countries facing water scarcity are increasingly turning to desalination as a dependable source of potable water. However, reducing the energy intensity and environmental impact of desalination remains a critical challenge.
Technologies such as the PX Pressure Exchanger have become increasingly important because they enable operators to produce freshwater more efficiently while lowering operational costs and emissions.
As governments and utilities pursue decarbonization goals and seek to improve resilience against drought and climate-related disruptions, demand for advanced energy recovery technologies is expected to continue rising.
For Saudi Arabia, the new desalination facility will not only strengthen water security but also support economic growth, tourism, and religious activities in some of the nation’s most important regions.
Upon completion, the project is expected to provide affordable, drought-resistant water supplies for approximately one million people, reinforcing the Kingdom’s commitment to sustainable infrastructure development and long-term resource security.
With its highly efficient PX technology playing a central role in the plant’s operations, Energy Recovery is positioned to contribute significantly to one of Saudi Arabia’s most important water infrastructure initiatives under Vision 2030.
