Profile

Twenty65 is a UK-focused initiative specializing in water innovation and sustainable water solutions. Established in collaboration with the Engineering and Physical Sciences Research Council (EPSRC) from 2016 to 2021, it brings together academic researchers and industry partners to tackle prevailing water management challenges. Based in Sheffield, the team comprises leading academics, including Prof Joby Boxall and Prof Vanessa Speight from the University of Sheffield, and aims to foster cross-sectoral collaboration to drive impactful changes in the water sector.

The initiative focuses on developing technologies that address the economic, sociological, and ecological challenges within the water cycle. It employs a multidisciplinary approach to design and implement scalable solutions that enhance water system resilience and adaptability. While Twenty65 does not directly serve as an investment firm, it plays a crucial role in promoting innovations through partnerships with more than 40 entities across the international water sector.

Notable contributions of Twenty65 include advancing demand-based water treatment technologies, minimizing carbon emissions through synergistic systems, and employing robotics for improved water management. These innovations have significant implications for public health and environmental sustainability, positioning Twenty65 as a key player in pioneering next-generation water solutions.
