Our Vital Mission

With less than 1% of the world’s water supply being of drinkable quality while the global population continues to grow, we are fast  approaching a crisis point. 


One of the biggest impacts we can have is to improve our ability to recover drinking quality water from polluted outputs caused by industry and agriculture.  Yet, many of the most innovative companies addressing this challenge are starved of growth capital as investors cluster around ‘sexy’ technologies like AI. 


Few stop to think that even AI data centres rely on water for cooling, not to mention all forms of life on earth!  Water Investment Network (WIN) has been created to address this challenge head-on by bringing together the world’s most innovative water treatment companies with aligned impact investors willing to provide patient capital. 


This is not philanthropy. We believe that the same capitalist profit motive responsible for the transformation in living standards that so many take for granted can also be the catalyst for massive improvement in water recycling across the planet.  


We very much hope you will join us on the journey.   

          Even AI Data Centres Need Water!
