Water Desalination Project Using Solar Power

The Water Desalination Project uses solar power and utilizes the availability of the Kingdom’s solar resources to meet the challenge of water sustainability.  The project was inaugurated by His Royal Highness Crown Prince Mohammed bin Salman bin Abdulaziz in November 2018.

The environmental impact is represented by removing high percentages of carbon emissions that arise due to large consumption applications, such as desalination, refrigeration, air conditioning and energy production in line with Vision 2030.


Economically, the Water Desalination Project is expected to reduce costs, allowing the redirection of natural energy to be sold in global markets.


The AlKhafji desalination plant uses reverse-osmosis technologies, developed at King Abdulaziz City for Science and Technology, and is powered by electricity produced by solar photovoltaics. The capacity of the desalination plant is 60,000 m³/day of clean water, with peak production of 90,000 m³/day. The solar power plant provides 10 MW of electricity daily to operate the desalination plant.
