Oman's Public Authority for Electricity and Water has appointed Septech Emirates to install the world's largest mobile desalination plant just outside of Muscat. The moveable plant, which will supply nearly 10% of the daily potable water needs of one million residents in the Omani capital, can be relocated to other coastal areas in the Sultanate as soon as the planned upgrades and extensions to the permanent desalination facilities that supply Muscat are made.
