Theseadvances strengthen our ability to assess humanimpacts on freshwater ecosystems across all scales Water is increasingly recognized as a strategicdriver of economic growth, security andemployment.Yet, current investments and actionsfall far short of what is needed, and poor water New evaluations of the benefits of closingthe infrastructure gap and the positive socio-economic impacts of water investmentpresented in this paper are crucial to spuraction.This paper shows that water infrastructureyields socio-economic returns significantly superior Connecting billions to safe water andwastewater networks will demand substantialinvestment in new infrastructure, and awhole new attitude towards water fromgovernments, industry and citizens.Education Besides the research done for this paper,progress in water science is accelerating. Francisco Betti,Head, Global IndustriesTeam; Member of theExecutive Committee,World Economic Forum Marco PastorelloChief Transformation Officeand Head of Research The urgency of addressing the global waterchallenge has been repeatedly highlightedby leading institutions and thought leaders,including the World Bank Group, the GlobalCommission on the Economics of Water and theOrganisation for Economic Co-operation and could unlock €8.4 trillion in additional GDP whilesupporting more than 206 million jobs worldwide. This report provides a strategic playbook ofbest practices, amplifying the voice of the waterindustry within the World Economic Forum andhighlighting how collaboration across finance,policy, technology, and culture can accelerateprogress.It presents 27 proven investment This paper specifically amplifies the voice ofthe water industry within the Forum and seeksto expand the global conversation on water.Beyond the imperative of ensuring safe water andsanitation for all, it calls on the sector to look furtherby accelerating infrastructure resilience, circularity The overarching message is clear: collaboration Policymakers can unlock investment throughclear strategies, effective regulation and improvedgovernance. Industry leaders can embed efficiencyand circularity into their operations, mainly as a Executive summary Coordinated action across government,industry and finance is needed to close Water infrastructure lies at the centre of theworld’s economic and climate resilience. To deliverequitable, resilient, sustainable and technologicallyadvanced drinking water and sanitation systemsfor all,global spending will need to double by2040. The total investment required amounts to€11.4 trillion ($13.2 trillion), revealing a financing establish coherent national water strategies, aligntariffs with the real cost of service and improvecoordination and data transparency to reducewater usage, improve efficiency of use and boostreuse, as well as bankability.Financial innovation,through instruments such as blue bonds, blendedfinance, and performance-based public-privatepartnership (PPP) and regulated asset base(RAB) models, can mobilize private capital whensupported by public guarantees and developmentfinance.Technology adoptionshould focus on The investment gap is determined by fourstructural drivers of demand that together definethe transformation agenda for the global watersector. One,equitable access,the imperativeto extend safe and affordable water to more than2 billion people and sanitation to over 3 billionwho still lack basic access. Two,infrastructureresilience, focused on modernizing ageing andinefficient assets that globally lose about 30% of Closing theglobal water infrastructure gapisachievable, but itrequires coordination andleadership. Governments should position wateras a strategic asset in national priorities, creatingpredictable frameworks, boosting efficiency and reuse,and deploying strategic public capital or guaranteesto attract private investment.
