The world’s specialist in water and sanitation solutions for under-served urban communities


Urban residents served
since 2005


People with improved water supply


People with improved sanitation


People who have received hygiene education

A quarter of urban populations worldwide live in slums – informal, unplanned, and densely crowded neighbourhoods.

In Sub-Saharan Africa alone, half of city residents live in such communities. Life in informal settlements is hard. Residents are forced to use unclean, shared latrines while paying 10x the price usually charged by the utility for water.
We exist to address these issues and achieve meaningful and sustainable change. We develop solutions that are affordable for the poor, financially viable for suppliers, and sustainable for the environment.

Why WASH matters

Our work is central to the achievement of two of the UN’s Sustainable Development Goals (SDGs)

It also contributes to the achievement of several other SDGs


Born out of a collaboration between the non-profit sector, businesses, academia and the water industry, collaboration is in WSUP’s DNA.
Around the world, we’re proud to work with a fantastic range of multi-sector partners, including:


WSUP has already helped millions of people access clean water, safe sanitation, and improved hygiene but with your help, we can reach even more. Any donation will positively change lives.
