Our HopeSafe and clean water for everyone, every day 

In Sub-Saharan Africa, 4 million people still lack access to safe water.
Every day, children and women walk long distances from their villages to collect water from unsafe sources, risking their health and safety along the way.
We believe that if everyone has access to safe and clean water, societies in Sub-Saharan Africa will become healthier, stronger, and more vibrant.

It was with this belief that Sunda Technology Global was born.
