Billions Worldwide Still Lack Access too Clean Water & Sanitation: A Looming Global Health Crisis
Updated August 27, 2025
A stark new report from the World Health Organization (WHO) adn UNICEF paints a sobering picture: despite decades of progress, billions globally remain deprived of access to safe water, adequate sanitation, and essential hygiene facilities. The joint study, “Progress on Household Drinking Water and Sanitation 2000-2024: Special Focus on Inequalities,” reveals not only the sheer scale of the problem but also the deeply entrenched disparities that leave the most vulnerable populations at risk of disease, social exclusion, and diminished opportunities. This isn’t simply a growth issue; it’s a basic human rights crisis with far-reaching consequences.
The Numbers Tell a Disturbing Story
The statistics are alarming.As of 2024, approximately 2.1 billion people - one in four globally - lack access to safely managed drinking water. A staggering over 100 million individuals are still forced to rely on untreated surface water sources, exposing them to a host of waterborne illnesses. The situation is equally dire regarding sanitation: 3.4 billion people lack access to safe sanitation, with a deeply concerning 354 million still practicing open defecation.
Beyond water and sanitation,1.7 billion people lack basic hygiene services, and a further 600 million have no hygiene facilities at all. Thes aren’t just numbers; they represent real people facing daily struggles with preventable diseases and compromised quality of life. as a public health expert with over 15 years of experience in global sanitation initiatives, I’ve witnessed firsthand the devastating impact of these deficiencies.
Disparities Deepen the Crisis
The report underscores a critical point: this crisis isn’t evenly distributed. Individuals in least developed countries are more than twice as likely to lack basic water and sanitation compared to those in more developed nations. They are also three times more likely to lack basic hygiene services.
Fragile states are particularly hard hit, experiencing drinking water coverage nearly 40 percentage points lower than stable regions. This highlights the interconnectedness of stability, infrastructure, and public health.Conflict and political instability often disrupt essential services, exacerbating existing vulnerabilities.Rural vs. urban: A Tale of Two trends
While rural communities have shown some improvement – drinking water coverage increased from 50% to 60% and hygiene access from 52% to 71% since 2015 - progress in urban areas has largely stalled. This is a critical concern, as urbanization continues at a rapid pace, placing increasing strain on already overburdened infrastructure. Effective urban planning and investment in water and sanitation systems are crucial to prevent a worsening crisis in cities.
The Gendered Impact: A Burden on Women and Girls
The report also highlights the significant gender inequalities embedded within this crisis. In many countries,women and girls disproportionately bear the duty for water collection,often spending over half an hour each day simply fetching water – time that could be spent on education,economic opportunities,or simply resting. This burden is particularly acute in sub-Saharan Africa and South Asia.
Moreover, the report emphasizes the challenges faced by adolescent girls during menstruation. While access to private spaces and basic menstrual materials is improving, many still lack adequate supplies to manage their periods with dignity and hygiene, impacting their school attendance, work, and social participation. Addressing menstrual hygiene management is not just a matter of health; it’s a matter of gender equality and empowerment.The 2030 Deadline looms: A Call to Action
with only five years remaining to achieve the Sustainable Development Goals (SDGs),the report delivers a stark warning: progress is not happening quickly enough. The goal of universal access to water, sanitation, and hygiene is increasingly unlikely to be met at the current rate. Ending open defecation, a practice linked to numerous health problems, also requires considerably accelerated efforts.
Expert Voices Demand Urgent action
Dr. Ruediger Krech, WHO’s Director a.i, Environment, Climate Change and Health, rightly asserts that water, sanitation, and hygiene are basic human rights, not privileges. He stresses the urgent need to prioritize action for marginalized communities.
Cecilia Scharp, UNICEF’s Director of WASH, echoes this sentiment, emphasizing the devastating impact of inadequate services on children’s health, education, and futures. She points out that girls are often the most affected, facing burdens ranging from
