Impact & Market

Africa Deserves Better

The water crisis in sub-Saharan Africa is one of the world's most pressing humanitarian and economic challenges — and one of the most significant market opportunities for disruptive technology.

The Global Problem

The Scale of the Water Crisis

2.2B

People worldwide — 1 in 4 — without safely managed drinking water

4B

People experience severe water scarcity for at least one month every year

443M

School days lost each year due to water-related illness

250M hrs

Spent every day — mostly by women and girls — collecting water

Water access challenge in Africa
Focus on Africa

The Crisis Is Accelerating

Sub-Saharan Africa faces a unique convergence of challenges that conventional solutions cannot address at the required scale or speed.

  • Only 64% of sub-Saharan Africa had access to even basic drinking water services in 2020 — the lowest of any region on earth (WHO/UNICEF JMP 2025)
  • 418 million people still lack even a basic level of drinking water service across Africa (UNICEF)
  • 1.42 billion people live in areas of high or extremely high water vulnerability — 450 million of them are children (UN-Water 2026)
  • Climate change: Eastern Horn faced 8 failed rainy seasons since 2010 (UNDRR)
  • Infrastructure gap: Africa needs ~$35 billion/year in water-sector capital investment (World Resources Institute)
  • Rapid urbanisation is outpacing water infrastructure in every major African city
  • The water crisis is a women's crisis: 1.1 billion women and girls (26%) lack safely managed water; they spend 250 million hours per day collecting water — 3x more than men and boys (UNICEF 2024; UN Women 2024)
  • 40 billion potential work hours are lost every year in sub-Saharan Africa alone to water collection — stifling women's economic participation and girls' education (World Bank)
