Water is essential to every aspect of human life. We need it to drink, prepare food, maintain sanitation, grow crops, care for livestock, and prevent the spread of disease. Despite its importance, access to safe water remains a major challenge for communities across the developing world.
The Global Need for Clean Water
According to the 2025 report from the World Health Organization (WHO) and UNICEF Joint Monitoring Programme, approximately 2.1 billion people lacked safely managed drinking water in 2024. This means they did not have drinking water available on their premises, free from contamination, and reliably accessible when needed. Of these people, 106 million were drinking directly from untreated surface water sources, including rivers and lakes.
These figures reveal a crisis that extends far beyond thirst. When communities lack clean water, families face greater health risks, children lose educational opportunities, women and girls often spend hours collecting water, and local economies struggle to develop.
Clean water access is not simply an infrastructure challenge. It is a fundamental requirement for building healthier, safer, and more prosperous societies.
Why Clean Water Is So Important
1. Protecting Human Health
Unsafe drinking water can expose people to dangerous bacteria, viruses, parasites, and chemical contaminants. Waterborne diseases such as cholera and other diarrheal illnesses can spread rapidly in communities without reliable water treatment and sanitation.
Children under five are particularly vulnerable to the consequences of contaminated water, including severe dehydration, malnutrition, and preventable death.
Providing safe drinking water, combined with proper sanitation and hygiene, helps communities reduce disease, improve nutrition, and relieve pressure on already stretched healthcare systems.
2. Giving Children Access to Education
In many rural communities, children must help their families collect water from distant wells, rivers, or other sources. The time spent collecting water can interfere with school attendance, homework, and other childhood activities.
Schools without reliable water supplies also face difficulties maintaining clean toilets, handwashing facilities, and a healthy learning environment.
Building wells, installing reliable water systems, and improving water access at schools can help children spend more time learning and less time meeting basic survival needs.
3. Empowering Women and Girls
In many communities, the responsibility for collecting household water falls disproportionately on women and girls.
Long journeys to find water can consume hours every day, reduce opportunities for employment and education, and expose people to physical danger. Carrying heavy containers over long distances can also create physical strain.
When clean water becomes available closer to home, women and girls gain more time to pursue education, earn income, care for their families, and participate in community life.
4. Supporting Agriculture and Economic Development
Water is essential for growing food, raising livestock, operating businesses, and supporting local industries.
When communities lack dependable water supplies, agricultural productivity suffers, food security weakens, and businesses face higher operating costs. Families may spend a significant portion of their income purchasing water or travelling to obtain it.
Investments in sustainable water infrastructure can help communities improve agricultural output, support small businesses, create employment, and strengthen local economies.
5. Building Resilience to Drought and Climate Change
Climate change, changing rainfall patterns, prolonged droughts, groundwater depletion, and population growth are increasing water pressures in many regions.
Communities that depend on seasonal rainfall or unprotected water sources are particularly vulnerable. When drought strikes, existing shortages can become emergencies.
Developing reliable water systems, protecting watersheds, collecting rainwater, improving groundwater management, and investing in appropriate treatment technology can help communities prepare for future water shortages.
Which Countries Need Clean Water Infrastructure Most?
The need for clean water varies significantly between countries and within their borders. Rural villages, informal settlements, displaced populations, and communities affected by conflict may face far greater challenges than national averages suggest.
The following countries and regions face particularly serious water-access challenges and merit close attention from governments, humanitarian organizations, development agencies, and private donors.
1. Chad
Chad faces significant challenges related to water infrastructure, rural access, sanitation, and climate vulnerability. Many communities depend on limited water sources, while drought and environmental pressures can threaten availability.
Investments in boreholes, protected wells, solar-powered pumping systems, water treatment, and community-managed water infrastructure can improve access while reducing the burden on families who must travel to collect water.
2. Central African Republic
Years of instability and displacement have disrupted essential services in parts of the Central African Republic. Some communities lack dependable water systems, sanitation facilities, and the resources needed to maintain existing infrastructure.
Priorities include repairing damaged water points, establishing safe water supplies for displaced families, improving sanitation in health centres and schools, and training local technicians to maintain equipment.
3. Democratic Republic of the Congo
The Democratic Republic of the Congo possesses substantial freshwater resources, yet many people still struggle to access safe drinking water. Geography, limited infrastructure, rapid urban growth, poverty, and conflict in some regions complicate water delivery.
The contrast demonstrates an important reality: having water resources does not automatically mean having safe water access.
Projects that protect springs, develop boreholes, extend piped networks, provide water treatment, and improve sanitation can help bridge the gap between available resources and community needs.
4. Niger
Niger faces substantial water-access challenges associated with its arid climate, recurring drought, poverty, and limited infrastructure in many rural areas.
Water investments must account for local geology and groundwater availability. Properly located boreholes, solar pumping, rainwater harvesting where appropriate, and sustainable agricultural water management can help communities improve their resilience.
5. South Sudan
Conflict, displacement, infrastructure shortages, flooding, and seasonal changes in water availability create serious challenges for communities in South Sudan.
During humanitarian emergencies, families may be forced to use unsafe sources, increasing the risk of disease outbreaks.
Urgent priorities include emergency water distribution, rehabilitation of wells, treatment and storage systems, sanitation facilities, and reliable water supplies for healthcare centres and displacement settlements.
6. Somalia
Somalia is highly vulnerable to drought and recurring water shortages. Many communities rely on groundwater, boreholes, water deliveries, or other sources that can become unreliable or unaffordable during prolonged dry periods.
Sustainable interventions include rehabilitating existing boreholes, improving groundwater monitoring, using solar-powered pumping where suitable, protecting water quality, and strengthening rainwater storage and drought preparedness.
7. Ethiopia
Ethiopia has made progress in expanding water services, but access remains uneven across rural and urban communities. Drought, population growth, infrastructure gaps, and difficulties maintaining water systems affect some regions particularly severely.
Investments in rural water points, protected springs, community water networks, sanitation, and maintenance training can help ensure that water infrastructure continues operating long after construction is complete.
8. Madagascar
Parts of Madagascar face severe water-access and sanitation challenges, particularly in rural communities and drought-affected areas. Climate variability, poverty, and limited infrastructure can leave families vulnerable to water shortages.
Appropriate projects include protected wells, boreholes where groundwater conditions permit, rainwater harvesting, school water systems, and community education on water treatment and hygiene.
9. Mozambique
Mozambique faces a combination of water infrastructure gaps, poverty, flooding, drought, and tropical cyclones. Extreme weather can damage wells, contaminate water sources, and disrupt existing distribution systems.
Water projects should therefore prioritize not only access but also resilience. Protected water points, elevated or flood-resistant infrastructure where appropriate, reliable treatment systems, and emergency water supplies can help communities recover from disasters.
10. Afghanistan
Afghanistan faces serious water challenges associated with drought, groundwater depletion in some areas, damaged infrastructure, poverty, and restrictions affecting essential services.
Communities require dependable water supplies for households, schools, healthcare, and agriculture. Projects must be designed around local water availability and include measures to prevent unsustainable groundwater extraction.
Important note: This list is an illustrative selection of countries facing substantial challenges, not a definitive ranking. The severity of water insecurity varies by indicator, year, and community. For the most accurate project selection, current national and local data should be reviewed before allocating funding.
Why Sub-Saharan Africa Deserves Particular Attention
Sub-Saharan Africa contains many of the communities facing persistent barriers to safe drinking water. Challenges include limited infrastructure investment, rural isolation, rapid population growth, poverty, conflict, and increasing climate pressure.
WHO and UNICEF data show that fragile contexts experience substantially lower coverage of safely managed drinking water than other settings. Rural communities also tend to lag behind urban populations.
However, water insecurity is not limited to Africa. Communities across South Asia, parts of the Middle East, Latin America, the Caribbean, and Pacific island nations also face challenges involving affordability, contamination, unreliable infrastructure, drought, or inadequate sanitation.
The most effective response is to identify specific communities with the greatest unmet needs rather than assuming every location within a country faces the same circumstances.
How Clean Water Projects Can Make a Lasting Difference
Delivering clean water requires more than drilling a well and moving on to the next community. Successful projects must be designed to operate safely, reliably, and affordably for years.
Build and rehabilitate wells
Wells and boreholes can provide essential access to groundwater when hydrogeological assessments confirm that sufficient water is available. Proper siting, construction, sanitary protection, and water-quality testing are crucial.
Install solar-powered water systems
Solar pumps can reduce reliance on fuel and provide water in locations where electricity is unreliable or unavailable. Systems must be appropriately sized, protected, and maintained, with plans for replacing components when necessary.
Develop community water infrastructure
Storage tanks, protected springs, gravity-fed systems, small piped networks, and public water points can improve access for entire communities. The right solution depends on geography, water availability, population size, and local capacity.
Improve water treatment and sanitation
Water sources may require filtration, disinfection, or other treatment depending on the contaminants present. Safe sanitation, handwashing facilities, and hygienic water storage are equally important in preventing contamination after collection.
Train and empower local communities
Long-term success depends on local participation. Training community members to operate equipment, monitor water quality, manage maintenance funds, and report breakdowns helps protect the investment.
Protect water sources
Groundwater and surface water must be managed responsibly. Poorly planned extraction can deplete aquifers, while agricultural runoff, sewage, industrial pollution, and inadequate waste disposal can contaminate supplies.
Every project should therefore consider environmental impacts, long-term water availability, and the needs of surrounding communities.
Where Should Donors and Aid Organizations Focus Their Efforts?
Organizations seeking to make a meaningful contribution should prioritize projects based on measurable need and the likelihood of delivering lasting benefits.
A practical assessment should consider:
- Access: How many people lack a reliable, safe drinking water source?
- Health: Are waterborne diseases or contamination posing serious risks?
- Vulnerability: Are children, displaced families, remote communities, or marginalized groups disproportionately affected?
- Feasibility: Is there a sustainable water source, and can the project be delivered safely?
- Maintenance: Who will operate, repair, and fund the system after installation?
- Impact: How many people will benefit, and how will results be measured?
Organizations should also publish transparent information about project costs, the communities served, water-quality results, infrastructure reliability, and maintenance arrangements. This helps donors understand not just what was built, but whether it continues to deliver safe water.
Clean Water Is an Investment in Human Dignity
Access to safe drinking water can transform daily life. It can help protect children from preventable illness, give families more time for productive activities, support local agriculture, improve school environments, and strengthen community resilience.
Yet lasting progress requires sustained commitment. Governments, international organizations, local leaders, engineers, businesses, and charitable organizations all have a role to play.
The goal should not simply be to provide water once. It should be to establish dependable systems that communities can maintain, afford, and trust for generations.
As the world works toward the United Nations Sustainable Development Goal of universal access to safe and affordable drinking water by 2030, the challenge is clear: progress must accelerate, and the communities facing the greatest barriers must not be left behind.
Clean water saves time, protects health, creates opportunity, and restores dignity. Investing in it is an investment in humanity’s future.
