World Water Day 2020: Desalination Technologies Provide Safe and Sustainable Drinking Water


Improvements in electrodialysis technology are creating new ways of producing freshwater. Funded by the EU, REvivED water is developing low-energy, sustainable solutions to address the growing demand for access to safe drinking water.

UNESCO estimates that around 2.2 billion people live without access to safe, clean drinking water. By 2050, up to 5.7 billion people could be living in areas where water is scarce for at least one month a year. With seawater making up 97.5% of the world's water resource, low energy desalination solutions will be a vital component of providing sufficient levels of good-quality drinking water for a growing population.

REvivED water brings together ten partners from six European countries to address the drinking water challenge. The project focuses on electrodialysis technology: using an electric current to make salts and other ions move out of salty water across a semi-permeable membrane. This approach has been successfully implemented across a range of settings.

Clean water for communities most in need REvivED water installed solar-powered desalination systems to produce fresh, clean drinking water for seven rural communities across Somaliland, Djibouti, India and Tanzania.
