Clean Water


Access to clean water is a fundamental human need that must be met if we expect to sustain progress toward ending poverty, ensuring access to education, and improving global health standards.

By the Numbers

  • Globally, 2 billion people use a drinking water source contaminated with feces. 1
  • 771 Million people still lack access to basic drinking water services.2
  • 122 million people still use surface water as their primary source of water.3

Access to clean water can change everything.

When families have access to clean water, it does more than improve health. Because, when your children are healthy, they can attend school regularly and excel in their studies. When you are healthy, you can take advantage of available economic opportunities. When you aren’t spending your hard-earned income on medication, you can invest in your family’s future.

We know how to make dirty water clean.

Our Rwandan volunteers know the value of access to clean water. And they are ready to do the long-term work to bring access to clean water to their communities. By equipping these local volunteers with the filter components, training, staff support, and the financial resources they need, we can help solve a global problem through local action.

After one year of having a filter, families report greatly improved health and fewer visits to the health clinic.


Our current focus is in Rwanda. Sub-Saharan Africa is ranked as one of the world’s most underserved areas for access to clean water.

Rwanda, Africa

1°56.633′S 30°3.567′E

Rwanda is a poor, rural country located in south-central Africa. With 80% of its population struggling to make it by with mainly subsistence agriculture, the 1994 genocide decimated their already fragile economic base. Today, though making strides to regain their economic stability, the population below the poverty line remains at nearly 45%. Specifically, we work along the Nyabarongo River, serving 8 rural sectors that use the river and adjacent swamps as their main water source.


Solving a problem starts with understanding the problem, which is why 20 Liters' approach to making dirty water clean starts with education. Once you understand the issue more fully, you can start to advocate for solutions. But advocacy alone isn’t enough. So, finally, we find ways to put your hands to work to make dirty water clean.
