As climate stress intensifies and water scarcity becomes a pressing challenge, the future of data centre cooling depends on diversifying water sources and reimagining how water is sourced and treated. This session explores how advanced membrane technologies are enabling the use of unconventional water sources such as 
sewage treatment plant effluent, rainwater, and seawater for reliable and energy efficient cooling. With compact designs, low energy consumption, and high recovery rates, innovation in membrane technologies are redefining sustainable cooling for data centres.
