The Water and Sanitation Providers Association (WASPA), was registered in November, 2002 under the Societies Act (CAP 108), Laws of Kenya as an association of Water Services Providers (WSPs) in the country.

The enactment of the Water Act 2002 created new institutions (water companies) to manage water resources in Kenya. The Companies took over the provision of water and sewerage services from their respective municipal councils. This therefore placed the water companies at the leading edge to consolidate the knowledge and share experiences, the water services providers formed WASPA to provide a forum for the various companies to learn from each other.
