Why does water inequality remain such a persistent global challenge?<\/h2>\n<p>The latest <a href=\"https:\/\/www.who.int\/publications\/m\/item\/progress-on-household-drinking-water--sanitation-and-hygiene-2000-2024--special-focus-on-inequalities\">WHO\u2013UNICEF report<\/a>, <em>Progress on Household Drinking Water and Sanitation 2000\u20132024, <\/em>released at World Water Week 2025, highlights a stark reality: around 2.1 billion people still lack safely managed drinking water, while 4.4 billion lack safely managed sanitation services, including safe disposal and treatment of domestic waste. \u00a0A further 1.7 billion people live without basic hygiene services, including facilities for handwashing with soap and water at home.<a href=\"#_ftn1\" name=\"_ftnref1\">[1]<\/a><\/p>\n<p>These figures reflect active deprivations embedded in structural, spatial and fiscal inequities.\u00a0 Water inequality is rooted in fractured systems, unsustainable planning and chronic undercapitalization, extending far beyond the absence of taps or toilets.<\/p>\n<h2>Q. What are the main structural factors driving these inequities?<\/h2>\n<p>There are two main interconnected reasons why these deficits persist:<\/p>\n<ul>\n<li>Geospatial disparity remains entrenched. Rural communities, fragile states and lower-income districts suffer from significantly lower access rates than more stable or urban settings. \u00a0In fragile contexts, for example, safely managed drinking water coverage is around 38% lower than more stable environments, pointing to systemic underinvestment where governance capacity is weakest.<\/li>\n<li>Incremental relative gains mask absolute backlogs. Global safely managed water coverage improved from 68% to 74% between 2015 and 2024, translating into hundreds of millions of additional people served. \u00a0But more than 2 billion people still have poor access to safe drinking water.<a href=\"#_ftn2\" name=\"_ftnref2\">[2]<\/a> \u00a0Population growth and underinvestment in operations, maintenance and resilience are outpacing service expansion.\u00a0 This reflects a broader imbalance between infrastructure delivery and long-term operational resilience.<\/li>\n<\/ul>\n<h2>Q. Is the issue primarily one of insufficient investment?<\/h2>\n<p>Yes, finance is a key part of the challenge, particularly given the scale of investment required. \u00a0\u00a0The World Bank estimates that developing countries spend around US$164.6 billion annually on the water sector. \u00a0At the same time, countries would need to increase annual spending on water supply and sanitation by a further US$ 131.4 \u2013 140.8 billion to meet Sustainable Development Goal (SDG) targets.<a href=\"#_ftn3\" name=\"_ftnref3\">[3]<\/a><\/p>\n<blockquote><p>Finance is a key part of the challenge, particularly given the scale of investment required<\/p><\/blockquote>\n<p>At a broader level, the OECD has estimated that achieving SDG 6 may require global investment exceeding US$1 trillion annually.<a href=\"#_ftn4\" name=\"_ftnref4\">[4]<\/a> \u00a0Other studies suggest that delivering universal access to safely managed water and sanitation by 2030 could require around US$ 114 billion annually<a href=\"#_ftn5\" name=\"_ftnref5\">[5]<\/a>, highlighting a substantial financing gap between current investment levels and future needs.\u00a0 Closing this gap will require sustained investment focused on resilient systems, integrated planning and long-term operational sustainability.<\/p>\n<h2>Q. Where do current water investment models fall short?<\/h2>\n<p>One of the central misalignments in the sector is between water service delivery and water resource management.<\/p>\n<p>In many countries, water and sanitation infrastructure is planned separately from the ecosystems and hydrological systems that sustain it.\u00a0 This means that investments frequently prioritize physical assets like treatment plants, pipelines and sanitation facilities without sufficient integration into hydrological planning frameworks. \u00a0Water supply systems may be built above aquifers without understanding recharge dynamics, while sanitation discharge can affect downstream ecosystems and long-term resource quality.<\/p>\n<p><em>Global water inequality in numbers<\/em><\/p>\n<ul>\n<li><em>1 billion people lack safely managed drinking water<\/em><\/li>\n<li><em>4 billion people lack safely managed sanitation<\/em><\/li>\n<li><em>38% lower access to safe drinking water in fragile states<\/em><\/li>\n<li><em>US$ 114 billion annually to deliver safe water and sanitation by 2030<\/em><\/li>\n<\/ul>\n<p>This fragmentation becomes even more problematic under climate stress, where operations may fail as water sources and supply volumes shift over time. \u00a0The SDG 6 framework already promotes integrated water resource management, including water-use efficiency, wastewater treatment, ecosystem protection and transboundary cooperation. \u00a0In practice, though, many capital programs remain siloed, focusing primarily on service delivery while neglecting watershed health, recharge zones and climate resilience.<\/p>\n<h2>Q. What would a more integrated approach to water investment look like?<\/h2>\n<p>The first priority is aligning water, sanitation and hygiene investment with integrated water resource management. \u00a0Investment planning must extend across both service delivery and resource management. \u00a0Water treatment plants, for example, should be coordinated with watershed protection and aquifer recharge strategies, while service contracts should include allowances for seasonal fluctuations and climate-driven variability.<\/p>\n<p>A second priority involves refining cost models to incorporate resource resilience and natural capital dependencies. \u00a0Traditional financial assessments often overlook ecological thresholds, ecosystem stress and long-term climate uncertainty. \u00a0Revised frameworks should incorporate lifecycle costing, ecological sustainability and climate-adjusted risk assessments.<\/p>\n<blockquote><p>Traditional financial assessments often overlook ecological thresholds, ecosystem stress and long-term climate uncertainty<\/p><\/blockquote>\n<p>There is also a need for blended finance structures that bridge the divide between revenue-generating assets and natural resource resilience. \u00a0Private capital typically concentrates on revenue-generating systems, while public or philanthropic finance may be better suited to supporting watershed restoration, recharge enhancement and ecosystem protection. \u00a0This creates a broader capital spectrum, extending from philanthropy through to commercial investment.<\/p>\n<h2>Q. Why is governance reform such an important part of the solution?<\/h2>\n<p>The fragmentation of water institutions often mirrors the fragmentation within investment models. \u00a0In many systems, water utilities and water-resource agencies operate under separate mandates, with limited coordination between them.<\/p>\n<p>Addressing this requires integrated governance structures, including stronger cross-ministry planning, shared budgets and joint monitoring frameworks that connect service metrics with resource indicators such as aquifer depletion, water quality and effluent performance.\u00a0 Without institutional alignment, investment decisions risk reinforcing existing inefficiencies rather than strengthening long-term resilience.<\/p>\n<h2>Q. Why do fragile and rural contexts require a different investment approach?<\/h2>\n<p>The financing gap is particularly severe in fragile and rural environments, where service provision costs are higher and infrastructure systems are more geographically dispersed. These contexts require targeted capital investment alongside operational subsidies capable of sustaining services over time.<\/p>\n<p>Funding models should also include dedicated support for resource protection measures such as watershed restoration and aquifer recharge enhancement. \u00a0Without these protections, infrastructure systems remain vulnerable to long-term environmental degradation and resource instability.<\/p>\n<h2>Q. What broader changes are needed to achieve universal water access?<\/h2>\n<p>The challenge is technical, financial and institutional.<\/p>\n<blockquote><p>Water inequality reflects fractured systems, unsustainable planning and chronic undercapitalization.<\/p><\/blockquote>\n<p>The solution depends on recognizing that infrastructure relies on resilient hydrological foundations supported by sustainable resource flows, comprehensive financing strategies and coordinated governance. \u00a0Investment models therefore need to connect service delivery with long-term resource resilience.<\/p>\n<p>This requires an end to siloed thinking and aligning water, sanitation and hygiene investment with integrated water resource management, while redirecting capital towards the areas where inequality remains most deeply embedded.<\/p>\n<p>As global water-policy discussions evolve, engineering solutions must increasingly be connected to hydrological science, financing structures and governance reform. \u00a0Only through this level of integration can water equity move closer to universal, sustainable access, supporting future generations as well as the billions of people who remain underserved today.<\/p>\n<h2>Connecting infrastructure with resilience<\/h2>\n<p>The persistence of global water inequality reflects deeper structural challenges in the way water systems are financed, governed and managed. \u00a0Expanding water infrastructure is essential. \u00a0Long-term progress also depends on strengthening the hydrological, institutional and financial systems that enable reliable service delivery.\u00a0 More coordinated institutions, climate-adjusted financing models and blended investment structures all have a role to play in building more resilient and equitable water systems.<\/p>\n<p>As Carlos highlights above, as climate pressures and population growth continue to intensify, the need for integrated approaches is increasingly urgent. \u00a0Bridging the divide in water access will depend on creating systems capable of sustaining reliable and equitable services over the long term, supported by infrastructure, resilient resource management and coordinated governance.<\/p>\n<h2>Water inequality: Five fast facts<\/h2>\n<ol>\n<li><strong>How many people still suffer from water inequality?<br \/>\n<\/strong>Around 2.1 billion people worldwide do not have access to safely managed drinking water, while around 4.4 billion people still lack safely managed sanitation, and 1.7 billion live without basic hygiene services.<\/li>\n<li><strong>Has global access to safe water improved in recent years?<\/strong><br \/>\nYes, but not fast enough.
