  • Description:
    An estimated 1.1 billion persons lack access to an improved water source. Hundreds of millions more drink contaminated water from improved sources because of unsafe water treatment and distribution systems and unsafe water storage and handling practices. The health consequences of inadequate water and sanitation services include an estimated 4 billion cases of diarrhea and 2.2 million deaths each year, mostly among young children in developing countries. The Safe Water System (SWS) is a water quality intervention proven to reduce diarrheal disease incidence in users by 22-84%. The SWS includes water treatment with chlorine solution at the point-of-use, storage of water in a safe container, and behavior change communication.

    The SWS project in Kenya began in 2000 with a CARE/Kenya pilot project in Nyanza Province. Results from this project showed a 56% reduction of diarrheal disease risk in rural communities. Based on this successful pilot project, PSI/Kenya began marketing an SWS product, a bottle of sodium hypochlorite solution branded as ‘WaterGuard’ in May 2003. Currently, PSI/Kenya sells approximately 50,000 bottles of WaterGuard per month. The WaterGuard product and distribution is cost- recovery, with marketing costs subsidized by PSI internal funding.
