World Bank WSP : Water and Sanitation Program.

Printer-friendly version

The Water and Sanitation Program (WSP) is a multi-donor partnership, part of teh World Bank Group, supporting poor people in obtaining affordable, safe, and sustainable access to water and sanitation services. The Program began in 1978 as a cooperative effort between The World Bank and the United Nations Development Program to look at cost-effective technologies and models for providing safe water and sanitation to the world's poor.

We work directly with client governments at the local and national level in 25 countries through regional offices in Africa, East and South Asia, Latin America and the Caribbean, and in, Washington D.C. 


WSP has led or supported many of the advances made within the water and sanitation sector over the last three decades.  We are able to share best practices across regions and place a strong focus on capacity-building by forming partnerships with academia, civil society organizations, donors, governments, media, private sector, and others. Our work helps to effect the regulatory and structural changes needed for broad water and sanitation sector reform.
