Saudi-listed ACWA Power, a major global developer and operator of water desalination projects, has signed a memorandum of understanding (MoU) with Veolia to further improve the development, design, operation, and performance of seawater desalination plants in Saudi Arabia and other international markets.
The agreement establishes a comprehensive collaboration covering the entire desalination value chain. The companies will jointly examine plant design, equipment selection, chemical dosing, monitoring systems, operating practices, and project execution, with a strong focus on improving energy efficiency and lowering operating costs.
Energy optimization represents a key pillar of the partnership. Engineers from ACWA Power and Veolia will work together to refine plant configurations, equipment choices, and operating strategies to reduce electricity consumption. Even relatively small efficiency improvements can generate significant savings when applied to large-scale desalination facilities.
The companies will also focus on chemical optimization. Better dosing strategies and more efficient chemical consumption are expected to reduce operating expenses while minimizing the environmental footprint associated with water treatment. Improved chemical management can also support more consistent plant performance and water quality.
Another priority is water-quality enhancement. Advanced monitoring technologies, improved treatment processes, and real-time assurance mechanisms will be incorporated into plant operations to help maintain water quality and respond quickly to changing operating conditions.
Veolia will additionally bring its engineering capabilities, technical expertise, and operational best practices to ACWA Power’s existing desalination portfolio. The objective is to improve plant efficiency and establish higher operational standards across individual facilities.
The partnership also includes closer cooperation during project delivery. Building on their previous collaboration, ACWA Power and Veolia intend to improve responsiveness, address operational challenges more quickly, and support the timely completion of current and future projects.
The potential impact of incremental efficiency gains is substantial. Four ACWA plants—Rabigh 3, Rabigh 4, Jazlah, and Shuaibah 3—each produce approximately 600,000 cubic meters of water per day. Saving just 0.1 kilowatt-hour per cubic meter could reduce annual electricity consumption by around 22 GWh at a single facility.
The collaboration will extend beyond Saudi Arabia to projects including ACWA’s desalination developments in Azerbaijan and Senegal, with capacities of 300,000 and 400,000 cubic meters per day, respectively.
Saudi Arabia relies heavily on seawater desalination for municipal water supplies, making efficiency improvements strategically important as water demand increases. The non-exclusive MoU does not commit specific desalination capacity but establishes a structured technical program for existing and future seawater reverse-osmosis projects.
Product & Chemical Commodity Price Impact
The move is likely to support demand for desalination chemicals, water-treatment chemicals, membranes, and specialty treatment additives, although improved dosing efficiency could reduce chemical consumption per cubic meter over time. For chemical commodities tracked by ChemAnalyst, stronger desalination investment in Saudi Arabia and overseas markets could provide a structural demand boost for products such as antiscalants, biocides, coagulants, flocculants, and cleaning chemicals. However, optimization and lower dosing rates may limit the immediate volume impact. Overall, prices could remain firm to moderately bullish for specialized water-treatment chemicals if desalination capacity expands faster than supply, while efficiency gains could restrain demand growth for commodity-grade treatment chemicals.
