What’s striking is the way Sweden combines high-tech water treatment plants with old-fashioned respect for the environment. Regular monitoring for pollutants, combined with tough regulations on industry, keeps water sources safe.

Sweden’s renewable energy policies also help, as clean energy means less risk of waterborne contamination from fossil fuels. Public campaigns remind Swedes to value and protect their water, making it a shared responsibility.

For many, grabbing a glass of water from the tap is a simple act with a deep sense of trust.

Norway: Sipping from Mountain Springs

Norway’s dramatic fjords and glaciers aren’t just beautiful—they’re the source of some of the world’s cleanest water. The Norwegian Water Resources and Energy Directorate reported in 2025 that 99% of the population receives water that meets the highest WHO standards.

Much of Norway’s supply flows straight from glaciers and mountain springs, naturally filtered through rock and soil before reaching homes. The government keeps a vigilant eye on water quality, making real-time data available and quickly addressing any threats.

Norwegians are proud of their clean water, and visitors are often surprised at how fresh it tastes, even straight from the tap in major cities. Investments in sustainable tourism encourage everyone—locals and tourists alike—to keep these waters unspoiled.

Eco-friendly attitudes are woven into the national culture, making clean water a source of unity and pride.

Switzerland: Alpine Purity in Every Glass

Switzerland’s snow-capped Alps aren’t just for skiers; they’re the heart of the country’s famously clean water. In 2024, the Swiss Federal Office for the Environment reported that 97% of residents have access to safe drinking water.

This remarkable achievement stems from a mix of rigorous water protection laws and cutting-edge treatment facilities. The Swiss are meticulous about monitoring water quality, running regular checks and swiftly correcting any issues, no matter how small.

Their approach is holistic, integrating sustainable agriculture and careful land management to shield water sources from pollutants. The result is water that tastes as pure as it looks.

For many Swiss, access to such high-quality water is a point of national pride and a symbol of the country’s commitment to health and sustainability.

Canada: Nature’s Reservoir

Canada’s vast wilderness holds about 20% of the planet’s freshwater, making it one of Earth’s greatest water stewards. According to Environment and Climate Change Canada’s 2023 report, 90% of Canadians have access to safe drinking water.

The sheer size of Canada’s forests, lakes, and rivers allows for natural filtration, reducing the need for excessive chemical treatment. Strict federal and provincial regulations keep industrial, agricultural, and urban pollution in check.

The government continues to invest in water infrastructure, especially for remote and Indigenous communities, to ensure everyone enjoys the benefits of clean water. Canadians often take pride in their ability to drink straight from the tap, whether in bustling Toronto or a cabin deep in the woods.

The national conversation increasingly focuses on the right to clean water for all, reinforcing the country’s stewardship role.

New Zealand: Land of Natural Filters

New Zealand’s rugged mountains and lush valleys create perfect conditions for naturally filtered water. A 2024 survey showed that 95% of New Zealanders have access to safe, clean water, a result of both geography and policy.

The government enforces strict environmental regulations, especially on agriculture, to prevent runoff from harming rivers and lakes. Restoration projects have targeted areas previously damaged by overuse or pollution, showing a commitment to reversing past mistakes.

Public awareness campaigns stress the importance of individual responsibility in conserving water and protecting waterways. Many Kiwis feel a deep connection to their land and water, with clean water seen as a birthright.

The tourism industry, too, has a stake in keeping rivers and lakes pristine, as visitors flock from around the world to experience New Zealand’s natural beauty.

Iceland: Geothermal Purity and Glacial Springs

Iceland’s water is legendary for its clarity and taste, thanks to its origins in glaciers and underground springs. According to a 2025 report from the Icelandic National Energy Authority, 99% of Icelanders enjoy access to safe drinking water.

Geothermal activity heats much of the country, but it’s the untouched glacial melt that fills taps with cold, clean water. The government’s strict regulations and constant monitoring keep pollution at bay.

Most Icelanders can trace their water straight from nature to their homes, with minimal processing needed. Renewable energy use further protects water sources from contamination linked to fossil fuels.

Residents and visitors alike marvel at the simplicity and purity of Icelandic water, recognizing it as a unique and precious resource.

India: A Daily Struggle for Clean Water

India’s water crisis is both staggering and urgent. In 2023, the Central Pollution Control Board revealed that nearly 70% of India’s surface water is dangerously contaminated.

Rapid industrialization and urban growth have overwhelmed existing water systems, while agricultural runoff introduces chemicals into vital rivers and lakes. Millions of people, especially in rural and low-income communities, face daily battles to find safe drinking water.

The government has launched various programs to address the problem, but progress is slow and complicated by the country’s sheer size and diversity. In 2024, the National Green Tribunal called for tougher regulations and better enforcement to protect water sources.

Climate change adds another layer of complexity, with unpredictable monsoons and droughts making safe water even scarcer. The health impacts, especially for children, are heartbreaking and underscore the need for urgent action.

Nigeria: Battling Infrastructure and Pollution

In Nigeria, water quality issues are deeply intertwined with issues of infrastructure, pollution, and conflict. A 2024 World Health Organization report stated that only 60% of Nigerians have access to safe drinking water.

Industrial waste, oil spills—especially in the Niger Delta—and poor sanitation contribute to widespread contamination. Outdated and poorly maintained water systems allow pollutants to seep into supplies, making even “improved” sources questionable in many regions.

Ongoing conflict in northern areas further complicates efforts to deliver clean water, as infrastructure is damaged or neglected. Despite government initiatives aimed at improving access and quality, progress is hampered by limited resources and logistical challenges.

The consequences are severe, with waterborne diseases remaining a leading cause of illness and death, particularly among children.

Pakistan: A Crisis of Contamination

Pakistan’s water woes have reached crisis levels. According to a 2025 report from the Pakistan Council of Research in Water Resources, over 80% of the country’s water sources are now contaminated.

The culprits include unchecked industrial pollution, excessive agricultural runoff, and a rapidly growing population straining already fragile systems. In many areas, safe drinking water simply isn’t available, forcing people to rely on unsafe sources with devastating health effects.

The government has acknowledged the problem and is working on water management reforms, but progress is slow, hindered by political turmoil and lack of funding. Waterborne diseases are common, impacting both health and economic productivity.

Addressing this crisis is essential for the country’s stability and the wellbeing of its people.
