The objective is to spread knowledge on low-cost water and sanitation options, with a focus on hands-on demonstrations.

They complement the efforts of the AU, AMCOW, NEPAD and other regional institutions, which provide political leadership and policy direction, by providing technical leadership in evidence-based policy advice, innovative and sustainable approaches, and advocacy services in the provision of water, sanitation and hygiene services in Africa.
WSA was established in 1988 as the African Regional Centre for Water and Sanitation (CREPA) in Burkina Faso and has now spread to 22 countries in West, East and Central Africa. Since its establishment, the organization has never ceased to develop and promote innovative, workable and context specific approaches and technologies in almost every thematic area in WASH.
