Desalination is an energy-intensive water source. It is a process which produces pure drinking water by pushing seawater through membranes to remove dissolved salts and minerals.
Singapore currently adopts reverse osmosis for its desalination, which uses about 3.5kWh/m3 of energy to make seawater drinkable. PUB is constantly exploring ways to reduce the energy required to ensure the sustainability of desalinated water. Please click here to find out more on PUB’s water-related research and development.
There are currently 5 desalination plants in Singapore. Find out more about each of our desalination plants below.
