The Problem

A Crisis Hiding in Plain Sight

Across sub-Saharan Africa, hundreds of millions of people rely on contaminated water sources every day. Existing solutions are too expensive, too dependent on infrastructure, or simply not reaching those who need them most.

🌍

418 Million Underserved

418 million people in Africa still lack even a basic level of drinking water service, concentrated in rural and off-grid communities.

⚡

No Grid, No Solution

Conventional water treatment relies on electricity and chemical supply chains — both unavailable or unreliable in the communities that need water most.

💧

Climate Intensifying the Crisis

Eastern Africa has experienced 8 failed rainy seasons since 2010. Drought, pollution and rapid urbanisation are accelerating water scarcity across the continent.
