A desalination plant for a petrochemical complex

Following its construction of the Jubail I desalination plant, Veolia has been selected by Marafiq to design, build and operate Saudi Arabia’s largest reverse-osmosis desalination plant with ultrafiltration technology, known as Jubail II.


Water is a scarce resource in the Persian Gulf region. During the 1970s, the Saudi government appointed a royal commission to develop the two industrial cities of Jubail and Yanbu. Its goal was to establish infrastructure and facilities that would spur development of a diversified manufacturing base designed to help Saudi Arabia become less dependent on oil revenue. Over time, these two industrial areas have developed an increasingly critical need for water.


Veolia combines two seawater treatment solutions: ultrafiltration and reverse osmosis, to minimize this new plant’s impact on the environment and meet the very strict water quality standards required by Marafiq. The combination of these various processes will ensure a secure water supply, limit the risk of plant failure and extend its lifespan, while at the same time reducing the site's energy requirements and costs.

With a capacity of 178,000 cubic meters/day, the new plant is scheduled to come on stream in June 2015 and will serve the Sadara petrochemical complex built in Jubail by Dow Chemical and Saudi Aramco.

Thanks to our technology and expertise in operation and maintenance, we can provide significant savings in energy costs
