Potable Water

The potable water system consists of production facilities, networks, pumping stations, and strategic storage facilities. It supplies potable water for the industries in Jubail 1 & 2, which is a vital utility for the continuous operation of all primary and secondary sectors. The same water is used for drinking in the community areas after Re-mineralization and disinfection with Chlorine Dioxide. The potable water network has main transmission lines and several distribution lines with manned and unmanned pumping stations. It consists of bulk and local storage tanks with a total capacity of more than 2.4 million cubic meters.
