This book provides an overview of the digital tools available in the market as well as the impact of digitalisation on the water sector by sharing Singapores experiences. PUB, Singapores National Water Agency, unveiled its SMART PUB Roadmap in 2018 to digitalise Singapores entire water system to improve the utilitys operational excellence and meet the nations future needs. This book shares PUBs digitalisation drive, highlights the deliberations behind its decisions, showcases its projects, and underlines the infrastructural, cybersecurity and human elements in digitalisation that other water utilities need to consider in crafting their own path forward.To guide the digitalisation efforts, PUB has come up with four major goals: to create value for the utility through new capabilities, more efficient operations, a better work environment, and improved customer service.With these goals, PUB has been able to focus their research and investments, plan their digitalisation journey in greater detail, and consider more deeply how to collect and use data in innovative ways.
