The WASH Alliance International is a multi-national consortium of over 100 partners worldwide. We work together with local NGOs, governments and businesses to make sure everybody on this planet has sustainable access to water and sanitation.


As WASH Alliance International we envision a world where all people have access to sustainable and affordable water and sanitation services.
This is a world where all people can live under hygienic living conditions to improve their health, dignity and economic living standard.

Our goals

With our programmes we aim to achieve increased sustainable access to and use of safe water and sanitation services. To realize this overall ambition, we have formulated two supporting objectives:

  1. Increased improved access to and use of safe water and sanitation services and improved hygiene practices
  2. Civil society actors are strengthened to jointly and individually better respond to the needs of the communities and influence decision making on WASH service delivery
