World Bank Highlights Saudi Arabia's Leadership In Low-Energy Desalination Technologies And Water Management

The World Bank has acknowledged Saudi Arabia's advancements in the water sector, especially in desalination, as highlighted in its report, "Gulf Economic Update: Navigating the Water Challenge in the GCC – Paths to Sustainable Solutions." The Kingdom is recognised for its leadership in improving efficiency and reducing energy use.

Among the notable achievements is the Shuaiba-5 desalination plant. This facility stands out with a production capacity of 664,490 cubic meters daily. It has set a new standard for energy efficiency by recording an energy consumption rate of only 2.34 kilowatt-hours per cubic meter, significantly lower than the usual 4 to 5 kWh/m³ seen in other plants.

The remarkable operational efficiency at Shuaiba-5 results from several technical innovations. These include advanced reverse osmosis membranes that need less pressure and energy, alongside energy recovery devices that capture and reuse pressure during desalination. Improved pre-treatment systems also play a role by reducing fouling and extending membrane life.

Furthermore, integrating renewable energy sources, particularly solar power, has decreased reliance on conventional electricity. This shift not only cuts operational costs but also aligns with environmental sustainability goals. The report highlights this transformation as a strategic move towards achieving these targets.

The Saudi Water Authority is pursuing an ambitious plan to cut energy intensity in the water sector by 30 percent by 2030 compared to 2019 levels. This objective will be met through adopting advanced technologies and enforcing sustainable policies. Such initiatives are part of a broader vision to enhance efficiency across the sector.

The success of Shuaiba-5 serves as a global model for regions grappling with water scarcity issues. It underscores Saudi Arabia's leadership in crafting innovative solutions to tackle worldwide water challenges effectively.
